Abstract:
1. An image processing apparatus for compression coding image data, comprising: designating means for designating a mode for a quantization operation; first compression coding means wherein a quantization step and a parameter involved in a quantization operation can be changed; second compression coding means for decoding and re-compressing code data compressed by said first compression coding means wherein a quantization step and a parameter involved in a quantization operation can be changed; quantity-of-codes monitoring means for monitoring a quantity of code data generated with said first compression coding means and determining whether the quantity of code data reaches a predetermined volume or not; parameter setting means for making said quantization step the step on the next stage, in parallel by setting a parameter in said first and second compression coding means for adapting a quantization operation for the mode designated with said designating means, when the quantity-of-codes monitoring means determines that the quantity of code data reaches the predetermined volume; and controlling means for re-coding the code data previously generated by said first compression coding means by using said second compression coding means and storing the re-coded code data into predetermined storage means as code data after changing a parameter in said first compression coding means, in parallel with saving the coded data generated by said first compression coding means after changing a parameter as subsequent code data into said storage means, when a parameter is changed by said parameter setting means.
