Patent number: 6919972Abstract: Upon reading an A3-size sample image, a colorimeter that can read A3 size can be used but such A3-size calorimeter is expensive. For this reason, an A3-size recording paper sheet is cut into halves, i.e., two A4-size sample images, which are measured by an A4-size calorimeter. To prevent such troublesome operation, color patches are divided into nearly half groups, and these color patch groups are printed on an A3-size recording paper sheet to have their top positions on the opposite sides. In this way, after one color patch group is measured, the sample image is rotated through 180° and is set on the calorimeter to measure the other color patch group.Type: GrantFiled: September 12, 2001Date of Patent: July 19, 2005Assignee: Canon Kabushiki KaishaInventors: Shuichi Kumada, Yasushi Nakajima, Kenichi Naito, Hayato Kubo

Patent number: 6781128Abstract: An infrared radiation detecting device is constructed using a manufacturing method to increase the infrared radiation absorptance of the infrared radiation absorbing film. The infrared radiation detecting device has an infrared radiation absorbing film. In one embodiment, the infrared radiation absorbing film has a varying film thickness.
