发明名称 IMAGE PROCESSING DEVICE AND METHOD
摘要 <p><P>PROBLEM TO BE SOLVED: To provide an image processing device capable of improving the ease of access to a specific picture element contained in an image data after encoding and offering an image suppressed in picture deterioration. <P>SOLUTION: An image processing device 100 comprises a wavelet transformation portion 102 for performing wavelet transformation to an image block captured by an image capturing portion 101, a first entropy encoding portion 103 for encoding a high-pass factor after wavelet transformation, a second entropy encoding portion 105 for encoding a low-pass factor after wavelet transformation, a code amount determining portion 106 for determining the generated code amount of entropy code data, a quantization processing portion 107 for performing quantization and encoding processing to the image block, and a code output portion 108 for outputting code data. The code output portion 108 selects either the entropy code data or the quantized data according to whether the generated code amount is within a target code amount or not, and outputs code data of the target code amount to the image block. <P>COPYRIGHT: (C)2009,JPO&INPIT</p>
