There is provided an image-signal processor capable of supporting a plurality of CCD image sensors (10, 20), including a timing generator (110) providing timing signals, each with the same phase, to the at least two CCD image sensors (10, 20), to enable each of the CCD image sensors (10, 20) to output captured-image data in the form of an analog signal which a corresponding A/D converter converts into a CYMG signal; at least two image-processing parts (11, 21 ), 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 (50) combining horizontally or vertically at least two images being in the form of the YCbCr signal into a combination image and then storing the combination image in an internal memory, and, at the same time, scaling down horizontally or vertically the combination image while reading out the combination image from the internal memory (53), storing the scaled-down combination image in an external memory (54), and then outputting the scaled-down combination image in the form of an YCbCr signal from the external memory (54); and an image-conversion part (81 ) converting the YCbCr signal to an YUV signal. |
