IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, PROGRAM AND IMAGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image processing device capable of: random access to the data corresponding to an arbitrary area in image data; and improving the compression efficiency of the image data, an image processing method, a program and an imaging device.

SOLUTION: A compression section included in the image processing device includes: a frequency measuring portion for measuring the frequency of the dynamic range of the block consisting of pixel data of a predetermined number with regard to image data; a quantization word length allocation calculation portion for computing the quantization word length assigned to each dynamic range for every block based on the frequency; and a padding portion for adding 0 or 1 until reaching a predetermined code amount with respect to the compressed image data including the coding data for every block quantized based on the computed quantization word length by predetermined blocks.
