imagis co., ltd. ISM2300(s) preliminary datasheet confidential 2008-03-21 - 8/51 - 1. overview 1.1. description the ISM2300(s) is a high performance enhanced image processor for hand-held application such as mobile phone, pmp, pnd, game player, di gital camcorder and etc. the ?mobile xview tm engine? in the ISM2300(s) improves the visib ility and the quality of the image displayed on tft lcd/amoled. the ?mobile xview tm engine? makes the invisible, blur and noisy of image into the more visible, sharper, clearer and smarter image for human eye. it also improves the visibility of image displayed at outdoor sunlight. the ISM2300(s) means two types version, ISM2300s and ISM2300. the ISM2300s is the internally embedded sdram version and the ISM2300 is the non-embedded sdram version (non memory version). his/csbi dei/rsi scl sda vsi/rdbi dcki/wrbi input format converter output format converter host interface clock generator sdram sadd hso/csbo deo/rso vso/rdbo dcko/wrbo xtali xtalo vddp1 , vssp1 vddm, vssm vdda, vssa vddi(2) , vssi(2) pwm rstb vddp2 , vssp2 back light control noise reduction edge enhancer version option visual enhancer di[23:0] do[23:0] xview tm figure 1 block diagram 1.2. features 1.2.1. mobile xview tm engine z visibility enhancement - dynamic contrast enhancer - sunlight readability enhancer - black stretch - white stretch and blue stretch www.datasheet.net/ datasheet pdf - http://www..co.kr/
