OmniVision Technologies Single-Chip CMOS Image Sensors - "Camera On a Chip" - Open New NTSC/PAL Applications for Manufacturers.SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 19, 1998--OmniVision Technologies, Inc. today announced the introduction of the OV7500 (color) and OV7000 (B&W) Series CMOS image sensor A CMOS-based chip that records the intensities of light as variable charges similar to a CCD chip. Although initially used in less expensive digital cameras, the quality of CMOS sensors has improved steadily. CMOS sensors have advantages over CCDs. devices ("Camera on a Chip") designed for NTSC/PAL composite video A video color format that combines all three YUV video signals into one channel. The first video signal to include color, composite video transmits brightness/luma (Y) and colors/chroma (U and V) over one cable. NTSC, PAL and SECAM television sets have composite video inputs. applications. The OV7500 Series and OV7000 Series are single-chip analog camera (1) An analog video camera such as a VHS camcorder. See analog video and VHS. (2) A film-based still or movie camera. See film camera. devices with two on-chip composite video encoders that output a high-quality interlaced image interlaced image - progressive coding suitable for closed-circuit television (CCTV CCTV abbr. closed-circuit television CCTV closed-circuit television ). The NTSC (National TV Standards Committee) The committee that developed the television standards for the U.S, which are also used in Canada, Japan, South Korea and several Central and South American countries. Both the committee and the standard are called "NTSC. (60 Hz) encoder outputs a 508x492 pixel image (250K) at 30 frames per second. The PAL (50 Hz) encoder outputs a 628x582 pixel image (365K) at 25 frames per second. A 5-volt DC power supply and a timing source are all that are required to produce a standard NTSC or PAL composite video signal ready to plug into a standard television or video recorder. OmniVision's new single-chip analog imaging devices are ideally suited for a wide range of applications, including CCTV systems, consumer products, medical instruments, computer input, and security and surveillance systems, among others. CMOS image sensors have the inherent advantages of small size, light weight, low power consumption, high reliability and low cost. OmniVision's proprietary technology results in CMOS image sensors that have a wide dynamic range with anti-blooming and virtually no smear. The OV7500 and OV7000 Series products are designed to simplify the implementation of imaging applications. Numerous functions have been integrated on-chip and include Automatic Gain Control (AGC AGC Automatic Gain Control AGC Automotive Glass Cartridge (fuse) AGC Associated General Contractors AGC Associated General Contractors of America AGC Atypical Glandular Cells AGC Attorney-General's Chambers ), Automatic Exposure Control (AEC AEC US Atomic Energy Commission Noun 1. AEC - a former executive agency (from 1946 to 1974) that was responsible for research into atomic energy and its peacetime uses in the United States Atomic Energy Commission ), Automatic White Balance (AWB See House Air Waybill. ), Gamma Correction, Back Light Compensation and Automatic Black Level Calibration. The OV7500 Series also includes all color matrix processing on-chip. On-chip functions are managed through the programmable I2C bus interface. "These CMOS image sensors provide some of the highest quality image capture capability of any NTSC/PAL devices and are a great solution for mass-market applications, such as PC computers, PDAs and other hand-held devices, consumer products, security & surveillance and machine vision", said Bob Stroh, VP Sales and Marketing. The OV7500 Series is available for $17.00 in quantities of 10,000; the OV7000 Series is priced at $15.00 in quantities of 10,000.
