Publication number: 20120256818Abstract: The present invention relates to a display apparatus and a method, a storage medium, and a program which cause a so-called “hold-type display apparatus” to display an image that makes it difficult for motion blur and jerkiness to be perceived at a lower frame rate. Display of individual pixels of a screen on an LCD 12 is held in each period of a frame. A display controller 11 controls the display of the LCD 12 so as to time-sequentially increase or time-sequentially reduce the brightness of the screen in each period of a frame. The present invention is applicable to a display apparatus.Type: ApplicationFiled: June 13, 2012Publication date: October 11, 2012Applicant: Sony CorporationInventor: Yoshihiko Kuroki

Publication number: 20100245546Abstract: [Object] To capture a high-quality 3D image having an appropriate parallax level and a small chromatic aberration. [Solving Means] A light ray output from a subject is separated into left and right light rays by mirrors 141 and 143 in an area in which a diverging light ray output from a point of the subject is converted into a parallel light ray. When the subject is looked at from the right side, the light ray is reflected by the mirror 141 and is further reflected by the mirror 142. When the subject is looked at from the left side, the light ray is reflected by the mirror 143 and is further reflected by the mirror 144. The right light ray reflected by the mirror 142 is made incident on the image forming lens 151. The light ray made incident on the image forming lens 151 forms an image on a light receiving surface of an imaging device 171. The left light ray reflected by the mirror 144 is made incident on an image forming lens 152.Type: ApplicationFiled: August 26, 2009Publication date: September 30, 2010Inventor: Yoshihiko Kuroki

Publication number: 20100156926Abstract: An image display device is provided, with less color breaking in the field sequential method. A color component image with a relatively high luminance level is extracted as a fundamental image from an input image. A differential image is obtained by subtracting color component of the fundamental image from an input image, and is decomposed into a plurality of color components. The differential image for each color component is divided into two. The fundamental image is displayed at a middle timing of a frame period. The half-divided differential images are displayed at timings before and after the middle timing for the fundamental image so that the half-divided differential image with higher luminance level with consideration for visibility characteristic is displayed at a timing closer to the middle timing for the fundamental image.Type: ApplicationFiled: December 10, 2009Publication date: June 24, 2010Inventors: Norimasa FURUKAWA, Yoshihiko Kuroki, Ichiro Murakami, Mitsuyasu Asano, Tomohiro Nishi
