PROBLEM TO BE SOLVED: To provide an image processor which efficiently processes images inside a predetermined memory capacity and an imaging apparatus provided therewith. SOLUTION: A data memory 12 is provided with an input buffer 61 which stores the uncompressed data of images scanned by a scanner portion 2, and an image buffer 62 which stores compressed image data. An image-compressing portion 22 compresses pieces of image data, which have not yet been processed or have already been processed by a major image-processing portion 10, stored in the input buffer 61 one by one, and stores the compressed image data in the image buffer 62. A memory reconstructing portion 26 increases the input buffer 61 and decreases the image buffer 62, when the size of image data compressed by the image-compressing portion 22 is larger than the image buffer 62. Therefore, the area in the data memory 12, occupied by the image buffer 62, can be used as input buffer 61, and efficient image processing can be conducted.
