" "$% & ' asynchronous random- access mos image sensor aramis EVS25K is a user- friendly cmos integrated image sensor using a patented architecture developed by elecvision in order to simplify its integration into computer- based products. different from classic ccd image sensors or some newly introduced cmos image sensors, aramis EVS25K image sensor can provide a fully clock- less and x- y address based image readout. this permits null or simple interface circuit to connect the sensor to a computer or dsp. furthermore, it incorporates an array of 180x150 pixels with on- chip fpn elimination amplifier and aanlog/ digital converter. the wide range continuous full frame electronic shutter control ability (from 1us to 255ms) eliminates the need of many optical devices such as diaphragm and m echanical shut t er. this is particularly attractive to compact and economic products such as videophone- oriented camera module, telesurveillance, car vision systems, consumer products, high- tech toy etc. z 180x148 effective pixels z (176x144 in colour version) z on- chip in- pix el analog fram e- buf f er f or motion smear- less image capture z on- chip fixed- pattern- noise compensation z clock- less and x- y address based image readout z on- chip integrated video amplifier z on- chip 8- bit a/ d converter z low power dissipation ( < 200mw) z wide range continuous full frame electronic shutter z int ernal black ref erence pi x e l pi t ch : 12.1umx12.1um cmos active square pixel pi x e l n u m b e r : 180x150 pixels with 180x148 effective pixels in b/ w version (176x144 in color version) optical size: 2.2mmx1.8mm sensitivity: 9v/ lux.s @ b/ w version 2v/ lux.s @ color version sp e ct r u m sp a n 400~1100 nm dark current 25~30mv/ s @ 25 o c readout speed: 10mpixels/ s adc: on- chip 8- bit a/ d converter power supply: 3.3v or 5.0v electronic shutter: full frame shutter color filter: bay er ? s pa ck ag e : lcc- 48 package
