  • Patent number: 10636368
    Abstract: An image display apparatus includes: a display unit; a plurality of light emitting units; and a light-emission controller configured to individually control light-emission brightness of each of the light emitting units, wherein in a case where brightness of light applied to a region of the display unit on which a black region of an input image is displayed is less than or equal to predetermined brightness, transmittance of the display unit is controlled such that transmittance of the region of the display unit corresponding to the black region becomes higher than that in a case in which the brightness is higher than the predetermined brightness.

  • Patent number: 8442383
    Abstract: An image capturing apparatus selects one of image capturing conditions to be used for capturing images as a reference condition when a total of image capturing time of one frame in each image capturing condition to be used for capturing images is longer than one frame period at a predetermined frame rate, and captures images at the predetermined frame rate under the reference condition, and captures images at a frame rate lower than the predetermined frame rate under the other image capturing conditions. A playback apparatus detects a motion between frames of a moving image captured under the reference condition when the image capturing condition of the playback moving image is not the reference condition, and generates an interpolation frame for interpolating between frames of the playback moving image based on the detected motion.
