PROBLEM TO BE SOLVED: To cope with an image of high resolution, using an A/D converting part of low resolution. SOLUTION: This image processor is provided with: an RGB input connector 11 for inputting analog image signal; the A/D converting part 12 for sampling and digitalizing the image signal input in the connector 11; a CPU 29, a main memory 30 and a program memory 31 for determining the capability of sampling collectively the image signal input in the connector 11, based on a sampling speed of the A/D converting part 12, for sampling the image signal input using the A/D converting part 12 in the first sampling position of one pixel skipping, based on a determination result, and for sampling thereafter the image signal in the second sampling position of one pixel skipping shifted by one pixel thereto, an image conversion part 13; a frame buffer 16 for storing the image signal of digital value obtained from the A/D converting part 12 according to an original pixel array; and projection systems 17-28 for outputting the image signal stored in the frame buffer 16.
