Patent ID: 8368778

Claim:
An image-signal processor capable of supporting a plurality of CCD image sensors, comprising: a timing generator providing timing signals, each with a same phase, to at least two of the CCD image sensors, to enable each of the CCD image sensors to output captured-image data in a form of an analog signal that a corresponding A/D converter converts into a CYMG signal; at least two image-processing parts, each of which receives the CYMG image signal from the A/D converter and converts the CYMG image signal into an YCbCr signal through application of color interpolation; an image-combination part combining horizontally or vertically at least two images being in a form, of the YCbCr signal into a combination image and then storing the combination image in an internal memory, and, at a same time, scaling down horizontally or vertically the combination image while reading out the combination image from the internal memory, storing the scaled-down combination image in an external memory, and then outputting the scaled-down combination image in the form of an YCbCr signal from the external memory; and an image-conversion part converting the YCbCr signal to an YUV signal.
