  • Patent number: 7098944
    Abstract: In converting image sensing data into image data, a plurality of image sensing data meeting a predetermined condition are processed as a group of image sensing data. An image reproduction parameter is obtained from this image sensing data group, and each image sensing data of the image sensing data group is converted into image data by using the image reproduction parameter. Accordingly, an image reproduction parameter for obtaining an optimum reproduced image can be accurately set from the image sensing data group. Also, since a reproduction luminance level (range) is determined from the image sensing data group, the correlation between the luminances of image planes is not lost. This allows an easy comparison of reproduced images and prevents the boundaries of luminances from becoming unnatural when the reproduced images are synthesized.

  • Patent number: 7081909
    Abstract: To perform printing control to obtain printed products having different sizes in accordance with printing regions divided in the widthwise direction of a printing medium having a fixed width, a printing control method of performing heat transfer printing on a printing medium by using a heat transfer sheet checks whether to perform printing on the printing medium having a fixed width by dividing the printing region in the widthwise direction of the printing medium (S602). If printing is to be performed by dividing the printing region in the widthwise direction of the printing medium (YES in S602), the method controls printing for consecutive pages by making printing information of the consecutive pages to correspond to the printing regions divided in the widthwise direction of the printing medium.

  • Patent number: 6891556
    Abstract: In order to print an image at a high speed without using any large-capacity power supply unit, the image to be printed is segmented into grayscale-specific areas before printing, and the cumulative number of printing elements required to print the respective grayscale-specific areas is counted to predict a necessary power. On the basis of the prediction result, the image is then printed by selecting the highest convey speed from convey speeds at which upper limit powers used and rated average power consumption are determined. This makes it possible to provide an image printing method and apparatus which can realize high-speed image printing.
