  • Patent number: 8325164
    Abstract: The present invention relates to a display apparatus and method for presenting a moving image of less degradation to an observer who is a person viewing a displayed moving image, on the basis of human visual characteristics without unnecessarily increasing the frame rate. A control signal generation section 125 and data line driving circuits 133-1 to 133-4 control display so as to display a moving image made of 105 or more frames/sec on an LCD 131. The LCD 131 displays a moving image made of 105 or more frames/sec on the basis of the control of the control signal generation section 125 and the data line driving circuits 133-1 to 133-4. In the LCD 131, the display of each pixel on the screen is maintained during each frame period. The present invention can be applied to image display systems.

  • Publication number: 20120256818
    Abstract: 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.

  • Publication number: 20100245546
    Abstract: [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.

  • Publication number: 20100156926
    Abstract: 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.

  • Publication number: 20100157090
    Abstract: An imaging method, a recording medium, and a program which are capable of processing imaging data of a high rate in a manner similar to that of a normal frame rate. Image data captured by a solid-state imaging element capable of performing imaging at a high resolution and a high frame rate is supplied to a memory control unit. The memory control unit, at the same time as writing the imaging data input from the imaging element in a frame memory, reads preceding frames of imaging data that are recorded on the frame memory, and sequentially respectively outputs them in parallel, as video image data items for each frame, to respective camera signal processing units. Then, in the camera signal processing units, a video output unit, a viewfinder output unit, codec units, and recording units, processing similar to that in the case of a frame rate that is ¼ the imaging frame rate is executed.

  • Patent number: 7528879
    Abstract: An image processing apparatus comprises an image display unit for displaying a desired image in accordance with an image signal, and image pickup units disposed respectively on the left and right sides of the image display unit. An image picked up from the left side and an image picked up from the right side are displayed together to be synthesized as the desired image in an image display unit of, e.g., a terminal of a conversation partner. Display in eye-to-eye matching with the conversation partner is thereby realized. An image processing apparatus, such as a portable communication terminal, capable of realizing conversation in a natural eye-to-eye matching state with the conversation partner can be provided.
