ABSTRACT:
An image processing apparatus includes a reader for reading image data representing an original image, a compression circuit for compressing the image data read by the reader, and an MPU for causing the compression circuit to compress specific data before image data from the reader is compressed and for determining if a compression operation is normal. The apparatus also includes an expansion circuit for expanding the compressed data from the compression circuit. The MPU compares the specific data with expanded data obtained by expanding, by the expansion circuit, the compressed data obtained by compressing the specific data.
