Abstract:
1. An image processing apparatus for performing at least one of JPEG 2000 encoding and decoding processes, comprising: a JPEG 2000 hardware encoder-decoder which has a memory for wavelet transform and inverse transform with a specific capacity and performs wavelet transform and inverse transform of image information up to a specific tile size using said memory by only hardware components; an acquirer of tile size information for acquiring a tile size information of image data to be encoded or decoded; a determiner for determining whether the tile size acquired by said acquirer can be processed using only components constituting said JPEG 2000 hardware encoder-decoder or not; a selector for selecting one of a first process and a second process based on a result of a decision by said determiner, the first process being a wavelet transform and inverse transform process performed using only components constituting said JPEG 2000 hardware encoder-decoder and the second process being a wavelet transform and inverse transform process performed using other components than the components constituting said JPEG 2000 hardware encoder-decoder.
