  • Patent number: 7853095
    Abstract: A horizontal direction component pixel extractor extracts a pixel of interest and a horizontal direction component pixel thereof from an input video signal. A vertical direction component pixel extractor extracts the pixel of interest and a vertical direction component pixel thereof from the input video signal. A threshold setter sets a threshold value from the pixel of interest and the vertical processing direction component pixel thereof. A non-linear smoother non-linearly smoothes the pixel of interest using a horizontal processing direction component pixel in accordance with the set threshold value, thereby generating a video signal. A flat rate calculator calculates a flat rate in a vertical direction of the pixel of interest using a vertical processing direction component pixel. A mixer mixes the input video signal and the generated video signal using the flat rate, thereby outputting a horizontal direction smoothed video signal.

  • Publication number: 20100265281
    Abstract: The image display device includes a light source section having light emitting subsections; a display panel; and a display control section performing a control. An input frame image is decomposed into a plurality of field images and the field images are displayed in a field sequential manner. A differential image for each of the three primary-color components is obtained by subtracting a common luminance portion from the subsection-drive frame image. The differential image and a common image configured of the common luminance portion are sequentially outputted to the display panel in a time-divisional manner. In the first field period for outputting the differential image of a primary color component, corresponding primary color light is emitted, and in a second field period for outputting the common image, multiple kinds of primary color light, corresponding to the primary-color components configuring the common luminance portion, are emitted together.

  • Patent number: 7773824
    Abstract: The present invention relates to a signal processing apparatus and a method, a recording medium, and a program, in which portions except an edge can be smoothed while the edge whose change in pixel value is steep is held correctly. A pixel of attention is determined in step S11, and a neighboring pixel is determined in step S12. In step S13, a difference in pixel values between the pixel of attention and each neighboring pixel is calculated. In step S14, according to a relationship in size between the difference and a threshold value ?., flags are raised for the neighboring pixel and a neighboring pixel which are symmetrical. Furthermore, a flag is also raised for a neighboring pixel away from, in view of the pixel of attention, the symmetrical neighboring pixel for which the flag is raised. In step S15, 7-pixel taps centered around the pixel of attention are averaged by weight.

  • Publication number: 20100188433
    Abstract: The present invention relates to a display control apparatus and method, and a program that are capable of appropriately controlling the luminance of light to be emitted by backlights with simple processing. On the basis of an input image signal, a peripheral-representative-value computation unit (141) computes, as a peripheral representative value, luminance that is output by backlights of a block of interest and blocks in the periphery thereof among the backlights formed from a plurality of blocks. A peripheral-contribution-amount computation unit (142) divides the peripheral representative value by light-emission efficiency based on a light-emission profile that is an output luminance distribution when the block of interest emits light so as to compute the amount of peripheral contribution by peripheral blocks to the block of interest.

  • 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: 20100134527
    Abstract: The present invention relates to a display control apparatus and method, and a program which make it possible to prevent deterioration in image quality due to insufficient luminance of light from a backlight. A backlight luminance calculating section (121) finds the backlight luminance of light to be radiated by a backlight, on the basis of the image signal of a display image. A moving image determining section (122) determines whether or not the display image is a moving image on the basis of the image signal. A correction value calculating section (123) increases the last correction value by a predetermined value to obtain a new correction value when the display image is a moving image, and decreases the last correction value by a predetermined value to obtain a new correction value when the display image is a still image. An addition section (124) adds the correction value to the backlight luminance to correct the backlight luminance.

    Abstract: The present invention relates to a display control apparatus and method, and a program with which a luminance deficiency by a back light can be suppressed. The entire back light is divided into N display areas (blocks) (B1-BN).
