Publication number: 20020135631Abstract: 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 cummulative 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 consumptions are determined. This makes it possible to provide an image printing method and apparatus which can realize high-speed image printing.Type: ApplicationFiled: March 19, 2002Publication date: September 26, 2002Applicant: Canon Kabushiki KaishaInventors: Takashi Sasaki, Hiroshi Kyogoku, Yoshinobu Shiraiwa

Patent number: 6453066Abstract: An image processing method in which color-appearance matching of an output image to an input image is achieved regardless of ambient light. Color conversion is performed on image data representing an input image to fulfil color-appearance matching of an output image to be reproduced by an image, output device, to the input image. Color conversion is performed on the image data representing the input image obtained from the input device under a certain standard light source into image data dependent on a light source used for observation. The converted image data is further subjected to color conversion based on a reference white color determined when an observation is made. The resultant image data is output to the image output device.Type: GrantFiled: January 22, 1997Date of Patent: September 17, 2002Assignee: Canon Kabushiki KaishaInventors: Yoshinobu Shiraiwa, Toshiyuki Mizuno, Yumiko Hidaka
