Cypress Semiconductor has introduced a high-quality 3,0 megapixel CMOS image sensor designed to bring digital still camera quality to camera-enabled mobile devices. The new device takes advantage of Cypress' three-transistor (3T) pixel technology to improve low light sensitivity without increasing pixel transistor count or sacrificing image quality. In addition, it incorporates the company's patented Autobrite technology, which improves dynamic range so both bright and dark areas within the same image appear clearly.
The new device is Cypress' first image sensor targeted at mobile devices. It complements a stable of Cypress products for that market, including pseudo-SRAM and dual-port memories, timing chips, USB controllers for hard-drive enabled phones and PSoC mixed-signal arrays with CapSense technology for capacitive-touch sensing applications such as volume and backlighting control.
The CYIWOSC3000A camera phone imager is a 1/3-inch optical format sensor with an active pixel array format of 2048 x 1536 pixels. Autobrite adaptive wide dynamic range allows the sensor to operate up to 72 dB. The device is capable of 30 frames-per-second (fps) at full resolution and 83 fps at 640 x 480. It also offers an electronic rolling shutter and onboard, 12-bit ADC. The sensor also offers programmable controls including frame size, frame rate, gain, exposure, electronic panning, binning of rows and columns, linear and non-linear image, black offset correction, flip and mirroring - all on-chip.
