Disappointed There was no description of how much video you can record with this camera. I purchased this camera for the purpose of making videos. Handy size, greater starter camera! This was my first digital camera. It was perfect for the first year I had it - easily portable and navigable. Handy size, greater starter camera! This was my first digital camera.

Project Overview The objective of this project is to automate the process of taking high dynamic range (HDR) images using a conventional low dynamic range (LDR) camera. An HDR image is able to capture a much higher level of detail than a LDR image, as it is able to capture a much wider dynamic range of intensities than a regular LDR image is able to. To obtain a HDR image from a standard digital camera, a series of pictures must be taken at a variety of shutter speeds. This can be achieved through the use of a microcontroller to send appropriate commands to the camera. The user will interact with a remote control unit (RCU) containing the microcontroller in order to take pictures. After taking pictures, the user can either connect the camera to the PC or insert the camera's memory card into an appropriate memory card reader attached to the PC. Provided software then handles extracting images from camera's memory card and converting each series of pictures into high dynamic range images. The recovered high dynamic range image is then placed through a gradient domain compression algorithm, producing a final picture that may be viewed on a conventional display, such as a CRT or LCD monitor.
Figure 1: System Block Diagram
System Description: 2.1 System Description - The Camera: The digital camera to be used with this project is the Canon PowerShot SD100. It was chosen due to its low cost and accessible functions that can be interfaced with a computer and a microcontroller. The Canon PowerShot SD100 Camera specifications are listed below.

3 2.2 System Description - The Remote Control Unit: A remote control unit (RCU) containing an HCS12 microcontroller, USB host controller, and a number of buttons and lamps will be what the user attaches to the camera. The RCU will include a standard-size Type-A female USB port, provided by the USB host controller, to alleviate the need for any cables other than the standard camera-to-PC USB cable. The RCU will also contain a compartment to hold four AA rechargeable batteries used to power all contained components.
Figure 4: Remote Control Unit Connected to the Camera
4 2.2.1 System Description - The Digital Camera and the Microcontroller The camera will be attached to the remote control unit via USB, due to the prevalence of USB connectors in consumer level digital cameras. The choice of a microcontroller over a PC allows for portability of the image capture system. However, the HCS12 microcontroller does not have a native USB controller. To add this functionality, an MCU-to-USB host controller module, specifically designed for adding USB host functionality to microcontrollers, will be interfaced with the HCS12. This chip, the FTDI VNC1L, will allow the camera to recognize the remote control unit as a valid USB host in addition to making the USB protocol transparent to the HCS12. Product data sheets and schematics for the device are attached to this proposal as appendixes.

Figure 5: FTDI VNC1L MCU to USB Host Controller (VDIP1 Module)
5 2.2.1.1 System Description - The Communication Protocol The Picture Transfer Protocol (PTP) will be used for communication between the HCS12 and the digital camera, as a wide variety of camera manufacturers support this protocol. In addition, a number Canon PTP Extensions will be implemented to allow for changing the shutter speeds on Canon cameras. Our Canon PowerShot SD100 uses PTP and the Canon PTP extensions to communicate with a host computer. The microcontroller will act as the host computer and use PTP to deliver messages to the camera and receive messages from the camera. Canon cameras use a series of command and response blocks to send packets back and forth. They use a specific structure for their packets to be sent through a USB command protocol. The following tables describe the general structure of the command and response block of bytes used to communicate with the Canon Powershot SD100 camera. Communication Protocol: Structure of a Command Block
0000000: 0000010: 0000020: 0000030: 0000040: 0000050: xx yy UU VV xx SS cc xx xx xx yy yy yy xx xx xx SS SS SS xx xx xx xx yy yy yy yy UU 00 cc VV. (payload/arguments) : : : : : : : xx xx xx xx SS SS SS SS
length (word) cmd3 (word) cmd1 (byte) cmd2 (byte) Length (again) sequence number (word) must contain 0x10 for commands with cmd3=0x201, 0x20 for commands with cmd3=0x202.
length is the length of the block, excluding the first 0x40 bytes in block, and is never less than 0x10. cmd1 and cmd2 are each a single byte cmd3 is a word Sequence number is a word, sent back in command reply.
6 Communication Protocol: Structure of a Response Block
02 kk 00 kk 00 kk 00 kk yy 00 UU yy 00 VV xx xx xx xx SS SS SS SS
A normal response block will be at least 0x54 bytes long. yyyy will contain an altered copy of cmd3. The high-order byte of cmd3 will be incremented from 2 to 3 (0x2010x301, 0x2020x302). UU will contain a copy of cmd1. VV will contain an altered copy of cmd2, incremented by 0x10 (0x110x21, 0x120x22). The first word of the response block will not contain the length xxxxxxxx will contain the length as a low-endian 32-bit integer at 0x48. This is the length of the useful information, i.e. (total block length)-0x40. SSSSSSSS at 0x4c is just a copy of the word that was sent to the camera in this location; it can be used to match a response to the command that elicited it. kkkkkkkk at 0x50 seems to be a status code; it will be zero if the command succeeded.

7 2.2.2 System Description - User Interface (RCU) The following diagram shows the general layout of the Remote Control Unit I/O interface. Four rechargable AA batteries (rated at 1.2V each) are required to power the remote control unit.

Figure 6: Remote Control Unit User Interface When the RCU is turned on by the on/off button, the microcontroller communicates with the camera, and if a session is established succesfully, the ready light will turn on. Otherwise, the error lamp will become lit. To take a series of images for HDR compilation, the user may hit the start button, causing the ready lamp to turn off and running lamp to become lit. Once the process is finished, the running light lamp turns off, and the ready lamp becomes lit once again. If an error occurs during capture, such as the memory card becoming full, the error light will light up instead. A stop button is included to allow cancellation of the capture of an HDR image. The user may turn off the RCU by again hitting the on/off button, causing control of the camera to be released and battery power to the RCU cut off. The following circuits will be used for debouncing input buttons and driving the LED lamps on the RCU.

9 2.3 System Description - The PC The provided software will facilitate the transfer of images to the PC and conversion to an HDR image. Since the image captures will take a large amount of memory to store on the camera, it was decided to allow the user to read either from the camera or simply from the memory card. To accomplish this, the software will access files from generic mass storage devices, rather than through PTP/IP. 2.3.1 System Description - Processing Software To convert the captured set of LDR images to a single HDR image, a number of open source tools will be used. The first tool set, pfscalibration, allows for the calibration of the camera used to take the pictures and the recovery of HDR images from the multiple exposure images collected using the RCU. The second tool set, pfstools, provides a set of tools for reading and writing HDR images. This will allow for the storage and previewing of raw HDR images. Last, the pfstmo tool set allows for tone-mapping operators to be applied to HDR images, producing images which may be displayed on a LDR display device. This software contains the gradient domain compression scheme, along with a number of other tone mapping operators. The provided user interface software will utilize all three of these tools seamlessly to present the final tone-mapped image to the user, as well as save the final picture to a user-specified location.

10 2.3.2 System Description - User Interface (PC) A clean, easy-to-use UI is needed to make this part of the project successful. The UI needs to perform, at the very least, four minimal tasks.
Allow the user to calibrate his/her camera for optimal HDR image creation. Allow the user to select the range of images to be processed. Construct the HDR image from the selected range of images, perform tone-mapping to an LDR image, and save the final image to a location of the user's choice. This involves invoking programs supplied in the pfstools, pfscalibration, and pfstmo packages.
Display the resulting image to the user.

11 2.4 Operational Boundaries The camera needs to be placed upon a tripod for stability when taking the still pictures at various shutter speeds. Thus, portability of the camera system is limited by the portability of the camera, the tripod, and the remote control unit (RCU). The maximum distance which the camera can be from the RCU is determined by the maximum length allowed by a USB connection. The official USB data sheets specify a maximum cable length of three meters for low speed devices. Battery life is also major limiting factor for the portability for the RCU. The RCU must be able to run on a single battery charge for a considerable amount of time for the sake of convenience and cost savings. Four AA batteries are required to supply roughly 4.8V to each component in the RCU requiring power (the HCS12, LEDs, and USB Host Controller). Under typical operating conditions, the LEDs will draw 12mA (one LED lit), the buttons will draw 12mA, the HCS12 microcontroller will draw about 100mA, and the VNC1L USB host controller will draw about 25mA. This results in a total current draw of 149mA. Using 1800mAh AA batteries, this gives an estimated battery life of about 12 hours with constant use. This estimation may differ significantly to actual battery life achieved due to variables such as battery condition and temperature.
Analytical Component For proper capture of an HDR image, the camera needs to be stationary while taking the series of pictures, as does the actual image being captured. The capturing technique utilized has a very low tolerance for scenes with excessive motion or a shaking camera. Either of these may result in fuzzy and/or incorrect final pictures. The time it takes to capture the sequence of photos will be dependent upon the time it takes to capture each picture at a different shutter time in addition to the time it takes to store the photos to the memory card. The time the camera takes to save the image to flash memory in addition to the shutter speeds effect on the capture time for each picture can be derived either from research or experimentation. The time for taking a sequence of photos may be expressed as the following formula. Total Timen exposures = k =1

1 time memory writen shutter speed k
Equation 1: HDR Image Capture Time Equation For the microcontroller, more research needs to be done to further understand the PTP/IP communication protocol and Canon PTP extension for interfacing to the camera. The amount of memory needed for each sequence of photos will change since the number of photos taken depends on how much the shutter speed is to vary for one sequence of pictures. If nine is discovered to be the optimal number of pictures for the best resulting HDR picture at the lowest cost to memory, then nine times the memory of a standard picture for a camera is needed for capturing a photo using this technique. Camera specifications have been researched to obtain the mega pixel size, available adjustments, shutter speeds, lens type, interface, and protocol of the camera. Shutter speeds and timings to recover from taking a picture will have bearings on the timing algorithms used in the
13 microcontroller. The protocol and interface will impact how the microcontroller actually goes about telling the camera what to do. Last, the camera's mega pixel size will dictate how many HDR image sets may be taken with a single memory card. A Canon Powershot SD100 will be used since we already have one and it fits the requirements of this project.

Feasibility / Potential Problems The major difficulty of the project will be in controlling shutter speeds. Controlling the camera's shutter speed via the HCS12 uC to take numerous pictures will be necessary to the project. To resolve these difficulties, acquiring a camera that is well suited for remotely controlling the camera with documentation of its communication protocol is a necessity. Additionally, the protocol needs to be analyzed in depth in order to allow for proper exchange of information between the microcontroller and camera. Nathan has been able to determine that the Canon Powershot SD100 has all the controllability and shutter speed capabilities that are required for this project. Therefore, Nathan will be primarily focused on continuing research on the PTP/IP protocol and Canon PTP extensions. Compiling the collected set of images into a single HDR image in a user-friendly way will also not be an easy task. To resolve this difficulty, a set of publicly available, open-source HDR processing tools will be utilized to allow concentration on the user-friendliness, rather than reinventing the wheel. However, using the tools to process the captured set of images must be done in a way that will be completely transparent to the user. This may be a difficulty in itself, and to resolve this, research will be done on invoking processes through a GUI and piping I/O quietly. Additionally, the software licenses for usage and redistribution must be analyzed carefully to prevent any license violations from occurring. John will be continuing investigation of the integration of these open-source software tools with the software UI, maintaining userfriendliness in the software UI, and preventing licensing issues. Last, finding an appropriate interface and power supply for the entire remote control unit package may also be a difficult task. Due to the complexity of the USB protocol, a drop-in USB Host Controller must be integrated with the project. Although the USB Host Controller selected
16 for the project is specifically targeted for use with microcontrollers, it will undoubtedly not be plug and play. In addition to this, the remote should be portable, so support for batteries must be included in the design. Using standard size rechargeable AA batteries will help to make powering the circuit easier, as battery housing for such batteries is easy to obtain. Additionally, using standard size batteries will lower the cost of operation and will be easier to replace than an exotic solution. To avoid draining batteries needlessly, low-power circuitry as well as low-power modes for the microcontroller have been researched by Angela. The serial communication interface of the HCS12 microcontroller has WAIT and STOP power-saving modes which may be used to conserve power after the microcontroller has been idle for a few minutes. However, experimentation is still required to see exactly how much power is saved by using these modes. Angela will continue to investigate how to best implement these power-saving features into the project, as well as investigate the integration of the USB host controller with the HCS12 microcontroller.

Testing Strategies There are two main components to test in this project: the PC user interface and the remote control unit (RCU). Fortunately, these components may be tested independently of each other. The PC user interface may be fully tested with manually-created exposure sets, but a final check will be performed with a set generated using the RCU. The RCU will be tested piecewise by further breaking the RCU down into the RCU user interface, the microcontroller software for camera control, and the RCU power system. Each of the remote control unit sub-components will first be unit tested as much as possible before any integration testing is performed. For the PC user interface, a number of tests need to be performed. First, the UI needs to be able to start up properly and allow the user to select a number of images (and only images). Next, the camera calibration function must be tested, along with the ability to load and save camera calibration information. Last, the actual image processing must be tested by clicking the process button with a list of images loaded and the camera successfully calibrated. Fail-over testing will be performed in depth in order to prevent a number of user errors from occurring. For the RCU, thoroughly testing the microcontroller camera control software is absolutely crucial. For this reason, a detailed testing strategy has been developed to not only insure proper operation, but to help keep development of this component on track. Each of the following tasks must be completed in order before moving to the next task. 1. Setup a. Layout physical connections between camera and computer b. Establish and verify a complete functional program (Canon Capture) 2. Phase 1 a. Verify that the camera is recognized by the computer b.

Attempt to send shutter speed controls through packets from HCS12 e. Take series of pictures at different shutter speeds f. Remove, download, and verify images to see if it used different shutter speeds The remote control power system must be tested in order to ensure that adequate power is being delivered to all components and that power can be delivered for a reasonable amount of captures. The HCS12, VDIP1 Module, and I/O circuitry will be tested individually and as a complete system to ensure that everything works with the 4.8V supplied by the battery pack. Additionally, any power saving code written for the microcontroller must be tested for proper operation in order to help maximize battery life without interfering with the regular operation of the rest of the device. For the remote control user interface, testing is equally important. The circuitry and basic commands to turn on and off LEDs and accept button input may be tested independently of the other RCU components. However, the rest of the testing requires the camera control software to be completed. To test that the UI is working with the camera control software, the ready LED should light when the camera and remote are powered on. Once this is confirmed, the remaining tests may be performed. When the start button is hit with a camera with enough memory available, the camera should successfully take pictures with only the running light lit and when finished, return to only the ready light being lit. Additionally, failure scenarios should be tested, such as when the camera's memory card fills up during a capture sequence (resulting in the error

19 light coming on instead of the ready light), or the USB cable is unplugged during operation. Last, the stop button should be tested for proper operation (forcing an image capture to stop and return to the ready state if no error has occurred).
