The Vivitar 3315 powered by OmniVision's OV9620 1.3 MegaPixel CameraChip won the 2003 DIMA Sub $100 Point and Shoot Digital Still Camera Shoot-Out. Manufactured by Vivitar, the Vivicam 3315 Digital Still Camera using the OV9620 1.3 Mega-Pixel CameraChip received a first-place award in the sub $100 Point and Shoot Digital Still Camera category. "This is a significant market achievement for OmniVision" stated Vern Klein, Director of Product Marketing at OmniVision. "Winning both the DV Camcorder and the sub $100 DSC awards is a huge statement of quality for both OmniVision and CMOS. OmniVision continues to make high quality digital imaging affordable to consumers." Page 1
The Digital Imaging Marketing Association (DIMA) digital camera shoot-out was held in Las Vegas, NV, during the DIMA 2003 Annual Conference at the Mandalay Bay Resort, concurrent with the Spring 2003 Photo Marketing Association (PMA) tradeshow. At the DIMA competition, cameras were divided into three main categories, Point-and-Shoot, Prosumer/Professional, and Commercial. Prints from each camera were then shown anonymously from Sunday, March 2, through Wednesday, March 5, in the "DIMA Shoot-Out Voting Booth" on the PMA 2003 Trade Show floor at the Las Vegas Convention Center. Images from the Point-and-Shoot cameras were printed on a Fuji Frontier 350 Digital Minilab supplied by Fuji Photo Film. PMA 2003 trade attendees (non-exhibitors) evaluated the results and cast ballots for the best print in each category. The entries were voted upon by trade attendees, based on the overall quality of the digital print and the accuracy of color as compared to samples of fabric worn by studio models. Cameras with the most votes within each category were announced at a press conference on Tuesday, March 4 at the convention center. Seventy-one digital camera entries and twenty-four manufacturers participated in the competition. In total, eleven digital cameras were named winners in their respective classes. OmniVision will be demonstrating their CameraChip technology in booth #3160 at the CTIA Wireless 2003 Show, in the Ernest N. Morial Convention Center in New Orleans, La. March 17-19.
