Title:
画像処理装置、及び画像処理のためのプログラム
Document Type and Number:
Japanese Patent JP4428028
Kind Code:
B2
Abstract:
An image processing device and program are provided which, while enabling faster overall processing if image data comprises a color image, maintains high quality of printed images. If RGB grayscale data is expanded into band memory 105, if judging from intermediate code the image type is other than a bitmap, the pattern is solid or a binary pattern, and moreover RGB grayscale values are "00000000" (binary) or "11111111" (binary), simplified expansion into band memory of RGB grayscale data as gray data is performed. In other cases, the RGB grayscale data is expanded without modification into band memory 105. In the case of gray data, color conversion processing using a color correction table is not performed, but interpolated values of "00000000" and "11111111" are taken. Thereafter the data is compressed and output from the host computer 1 to a printing device 2, and printing is performed.
