  • Publication number: 20110304893
    Abstract: This invention is directed to correcting a smear by a line-sequential reading scanner. To accomplish this, in a line-sequential reading type image reading apparatus (scanner), the first memory stores reference smear amount data of a smear occurred for each color component. The correction amount for the brightness value of each color component obtained by reading an original by an image sensor is calculated based on the reference smear amount data stored in the first memory and the brightness value level of a pixel on a preceding line. The brightness value is corrected based on the correction amount.

  • Publication number: 20100321324
    Abstract: Disclosed is a technology that prevents a part of a touch panel-equipped display displaying an ultrasonic tomographic image from getting dirty with a fingerprint or scratch when using a drag operation to change the content of the ultrasonic tomographic image displayed on the touch panel-equipped display. According to this technology, the display screen is divided into an ultrasonic image area A1 which displays an ultrasonic image P and an operating part display area A2 which displays buttons (Fov, Pos, ROI, and Dop) for selecting a change to be made in the ultrasonic image P. The operating part display area A2 has a touch panel, and when a finger F selectively touches one of the displayed buttons and is dragged, the displayed image P of the ultrasonic image area A1 is changed on the apparatus side according to the selected changes and drag direction.
