ABSTRACT:
An image data conversion device includes a variable-length code decoder which decodes compressed image data which has been compressed through processes of orthogonal transform, quantization, and variable-length coding. A data amount calculation unit calculates an amount of data that corresponds to a predetermined number of pixels from the results of decoding by the variable-length code decoder. A delimiter code insertion unit inserts a delimiter code in a position in image data where the amount of data calculated by the data amount calculation unit corresponds to the predetermined number of pixels.
