摘要： An image processing apparatus executes an error diffusion process to multivalue image data consisting of a plurality of density components. A first processor executes the error diffusion process by changing at least one of a quantization threshold value and a quantization diffusion coefficient which are used for the error diffusion process based on a value of the multivalue image data of the density components or a value calculated from the multivalue image data value. A second processor executes the error diffusion process by setting the quantization threshold value and the quantization diffusion coefficient which are used for the error diffusion process into fixed values. An error diffusion processing controller controls to execute the error diffusion process to at least one color among the density components by the first processor and execute the error diffusion process to other density components by the second processor.

摘要： Image data, or RGB luminance data input from a host computer, is color-converted by LUT into 8-bit CMYK density data for each ink color. The CMYK density data is divided into predetermined regions and, based on a gray scale value for each of the divided regions, ink application volumes are calculated. According to the calculated ink application volumes, the 8-bit processing liquid application data S is generated. Then, the CMYK density data and the processing liquid application data undergo output gamma processing, after which they are quantized by a quantization processing unit into 1-bit ejection data for each nozzle.

摘要： When a plurality of sheets of images are laid out and outputted in one page and characteristic amounts of multivalued image data are obtained to perform preferable image correction, the characteristic amounts of all the images to be recorded in the corresponding page have been beforehand obtained to calculate preferable image correction parameters. Therefore, a waiting time until the start of actual printing has been long. To resolve such an inconvenience, an image processing apparatus of the present invention is characterized by comprising correction amount deciding means for deciding an individual correction amount with respect to each of the plurality of image data, and correcting means for correcting the image data based on the individual correction amount, whereby the correcting means respectively corrects the images in accordance with the correction amounts which have already been decided, in a state where the correction amount deciding means has not completed the decision of the correction amounts for all of the plurality of the image data.

摘要： A print-direct printer for receiving and printing JPEG data from a DSC divides the area of a memory into a plurality of blocks, stores the received JPEG data in the memory on a block-by-block basis and decompresses the compressed JPEG data that has been stored in the memory, thereby expanding the JPEG data into image data. If it is determined that JPEG data to be expanded next has not been stored in the memory, then the DSC is requested for JPEG data corresponding to at least one block, in an amount that is less than the maximum amount of data transferable from the DSC, in addition to the JPEG data to be expanded.

摘要： An information processing apparatus comprising a power unit, a first control unit and a second control unit in which power supply is controlled based on a control signal from the first control unit, wherein when electric power supply from the power supply unit has been stopped and then the electric power supply from the power supply unit has been started, if update of a memory of the first control unit has been instructed, the first control unit transfers the content of a flash ROM in the first control unit into the memory thus updates the content of the memory. At this time, the second control unit is kept in a power-off status by a control signal line until the update of the memory is completed. After the completion of the update, power-on is notified by the control signal line, and the reset status of the second control unit is released.
