    摘要: A histogram section determines as a motion vector at a pixel of interest the candidate motion vector with highest frequency from among a candidate motion vector at the pixel of interest and candidate motion vectors at pixels neighboring the pixel of interest supplied by a template matching section, and supplies it to a motion-vector correcting section. The motion-vector correction section evaluates the confidence level of the motion vector supplied by the histogram section based on the luminance gradient around the pixel of interest detected by a luminance-gradient detecting section and a control signal indicating whether correction should be carried out supplied by the template matching section. If it is determined that the confidence level of the motion vector is low, the motion vector is corrected.

    摘要: A display control apparatus may include a necessary light emission level calculation unit that calculates a necessary attention block light emission level of a back light in an attention block which satisfies a necessary luminance based on an image signal. A first neighborhood block light emission level calculation unit may calculate a light emission level of first neighborhood blocks which satisfies a deficient luminance by a light emission contribution amount to the attention block through light emission in first neighborhood blocks of the attention block which satisfies the deficient luminance by the back light in the attention block. The back light in the attention block emits the light at the largest light emission level at which the light can be emitted and back lights in the first neighborhood blocks emit the light at the first neighborhood block light emission level.

    摘要: 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. The present invention can be applied to a liquid crystal display apparatus.
