  • Patent number: 8446434
    Abstract: An image processor enabling a user to quickly select desired images from a large number of images without scrolling repeatedly through the images. The image processor assigns image numbers to segments of a scroll bar and displays image data corresponding to an image number assigned at the position on the scroll bar pressed by the user. The image processor also reduces the number of image numbers assigned per segment of the scroll bar near the image number at the pressed position on the scroll bar to facilitate the user in specifying a desired image through a subsequent input operation.

  • Patent number: 7780259
    Abstract: The ink cartridge has a first detection target portion for detecting ink level and a second detection target portion for identifying the type of an ink cartridge. The ink level detection device uses an optical sensor to scan the first and second detection target portions of the ink cartridge, and detects ink level and the type of the ink cartridge, that is, whether the ink cartridge is containing standard amount of ink or large amount of ink. Therefore, the number of image formation on recording media can be estimated, and failure in image formation due to a shortage of ink in the middle of image formation can be inhibited.
