Patent number: 7319449Abstract: An aspect of the invention provides an image display apparatus that displays a plurality of input pixels which form input image data on a display section. In that case, each input pixel can be displayed in such a manner that display pixels having gradation values differing from the gradation value of the input pixel are combined. For example, when a pixel having a particular gradation value exists as an input pixel, the pixel is not displayed on the display section as it is being kept at the gradation value, but instead, is displayed in such a manner that a plurality of display pixels having gradation values differing from the gradation value of the input pixel are combined. As a result, the same gradation value is not displayed continuously. Therefore, this results in that the occurrence of crosstalk, which is problematical particularly in a TFD liquid-crystal panel, is reduced.Type: GrantFiled: June 22, 2004Date of Patent: January 15, 2008Assignee: Seiko Epson CorporationInventors: Katsunori Yamazaki, Takashi Kurumisawa, Masanori Ishida

Publication number: 20010010560Abstract: A focal-plane shutter for digital still cameras is constructed so that a first driving member for a first blade connected to the first blade is biased by a cocking spring to rotate clockwise and a second driving member for the first blade is biased by a driving spring to rotate counterclockwise. A driving member for a second blade connected to the second blade is biased by a driving spring to rotate counterclockwise. An exposure aperture is fully opened before photographing, and when a cocking member is rotated in a clockwise direction in photographing, the first driving member is released from the holding of the cocking member and is rotated, and the exposure aperture is covered by the first blade. After that, when releasing members are separated from the iron cores of respective electromagnets, locks of locking members are released, and the driving members are rotated counterclockwise in turn. Consequently, exposure is carried out through a slit formed by the first blade and the second blade.Type: ApplicationFiled: January 31, 2001Publication date: August 2, 2001Inventor: Shigemi Takahashi
