... KS7332 INTRODUCTION PRODUCT SUMMARY KS7332 is a digital image signal handling IC aimed at improving image contrast and counter light correction, applicable to CCD-using video camera systems such as camcorders and surveillance cameras. KS7332 receives the CCD output as digital data, analyzes the image's luminance distribution, then outputs a signal with improved dynamic range of luminance and color difference ...

... KS7332 The preprocessing block receives the 10-bit ADC output, carries out digital clamping, black line detection & correction, and preprocess low pass filtering. The histogram generating block uses the preprocessing block's output to generate a probability density function of the image signal luminance output, and stores it in line memory. It also generates a signal for adjusting luminance distribution and sends it to the segmentation block and the look-up-table generating block ...

... KS7332 Look-Up-Table Block The look-up-table block uses the output of the histogram generating block and the segmentation block to generate a conversion function for the improvement of dynamic range composed of the histogram integrating block, look-up-table generating block, and the look-up-table 2nd differentiation. ...

... KS7332 MICOM REGISTER TABLE OPERATION DESCRIPTION The start signal and clock operate in slave mode, so this part is nonsychronous to the rest of the system. The register setting is normally carried out for all segments within the field, and it is latched at negedge VD when scsn is restored to high. ...
