Title:
Image processing device and image processing method
Document Type and Number:
Japanese Patent JP6003042
Kind Code:
B2
Abstract:
In the printer, the correction content setting portion sets equal to or more than one correction contents, the decimation rate setting portion sets decimation rates for respective planes of Y, Cb, and Cr of JPEG data (compressed data) based on the set correction contents. Pixels are decimated at the set decimation rates and the decompression processing unit decompresses the JPEG data so as to generate image data. In this manner, decimation processing is performed in accordance with the plurality of correction contents. Therefore, for example, inverse quantization processing, inverse DCT operation processing, and the like, can be omitted in accordance with the correction contents. The decompression processing may be executed on a sampling image to be used for sampling when the contents of correction to be performed on the image data are determined and on a print image to be used for printing.
