easily integrated vga cmos sensor the icm105t gives handset and mobile consumer electronics makers a decided cost advantage in integrating small form-factor digital imaging functionality. the icm105t captures quality vga images with high sensitivity and lower power consumption. the high level of integration can speed up design times and lower the total bill of materials to implement digital imaging functionality in cellphones and a wide range of other electronic products. application sensor overview the icm105t is a single-chip digital color-imaging device incorporating a 640x480 sensor array. the icm105t delivers from 1 to 30 frames per second in a progressive manner. correlated double sampling is performed by the internal adc and timing circuitry. gain for raw data can be adjusted separately for each bayer pattern pixel. the 8-bit raw data output can be fed to other dsp, color processing, or compression chips. key benefits high sensitivity vga image - 640x480 format - supports 1/4?lens - automatic optical black compensation - dead pixel removal - correlated double sampling low bom cost - on-chip 9-bit adcs - sif input interface - operates at 2.8 v or 3.3 v (analog) low power consumption - 25 ma (@ 30 fps, 24 mhz) - 14 ma (@ 15 fps, 12 mhz) flexible features - electronic exposure control adcs - video and digital still camera modes - horizontal and vertical images the leader in cmos image sensors product brief icm105t vga cmos image sensor
