摘要:
A color printer 20 allocates all of the image processing memory resources for image processing on image data GD lined up in the main scanning direction of a print head IH, secures an amount of memory resources for each of the lined up image data GD, and releases the memory resources as the image processing completes. A CPU 51 secures image processing memory resources for an image datum 1 in the storage area of a RAM 53, and releases the secured memory resources when the image processing on the image datum 1 is complete. The CPU 51 repeatedly implements this processing on each image datum contained in one print job.

摘要:
An apparatus, method, signal and computer program product are configured to provide an output image adjustment for image files. A CPU of a color printer performs gamma correction and a matrix operation M on RGB color space image data derived from a matrix S operation. The CPU performs gamma conversion on image data using established gamma values. Matrix operation M converts the RGB color space to the XYZ color space. When executing matrix operation M, the CPU refers to a color space tag, contained in an image file produced at an image generating device, so as to preserve the color space used during synthesis of the image data, and performs the matrix operation using a matrix (M) corresponding to color space written in the file.
