    摘要: An image forming apparatus includes a print head provided with a plurality of discharge ports, a scanning unit configured to cause the print head to scan the same printing region on a recording medium a number of times, a generation unit configured to generate image forming data for each of scans, based on image information that has been input, and an image forming unit configured to perform image forming by discharging inks from the discharge ports on the recording medium according to the image forming data generated by the generation unit. The generation unit includes a division unit configured to divide the image information, while controlling division coefficients, using each of the discharge ports as the reference based on the division coefficients, and a quantization unit configured to quantize each of image information divided by the division unit.

    摘要: In an image processing apparatus, connected via an external bus to at least an external controller and an external storage device, input image data is processed by an image processor 2, then processed image data 1 and image data 2 are simultaneously stored into respective areas of an image buffer 4. The image data 1 is read from the image buffer 4 while it is stored in the image buffer, and the read image data 1 is processed by an image processor 5. The image data is outputted through an image output controller 6 and a bus I/F unit 1 to an external storage device 903 via an external bus 101. At this time, the result of processing on frame data by the image processor is preserved in correspondence with output of the image data 1 for one frame, and image processing and output processing on the image data 2 stored in the image buffer, for one frame, is started.
