  • Patent number: 9179163
    Abstract: An image processing device includes a decompression unit configured to decompress a compressed image signal, a gradation-dependent correction unit configured to perform gradation-dependent correction on the decompressed image signal, the gradation-dependent correction being a correction process in which the amount of correction varies among luminance gradations, and a compression error correction unit configured to perform compression error correction in which input luminance values are selectively offset, on the decompressed image signal which has yet to be subjected to the gradation-dependent correction.

  • Publication number: 20140035898
    Abstract: A driver IC includes: a plurality of driver circuits that are individually provided for respective light modulation elements and drive the light modulation elements, in which the light modulation elements each perform light modulation on received light in response to an applied voltage; and a plurality of output terminals outputting signals derived from the respective driver circuits to outside. The driver IC is a single driver IC that drives the light modulation elements. The output terminals are disposed on sides of the driver IC, and the respective output terminals are disposed on the different sides for the respective corresponding driver circuits.

  • Publication number: 20140016869
    Abstract: A signal processing apparatus includes a representative value calculation unit and a low pass component extraction value calculation unit. The representative value calculation unit is configured to calculate, when areas obtained by dividing a frame image in units of a plurality of pixels are each assumed as a block, an average value of pixel values within each block as a representative value of the block based on an input video signal. The low pass component extraction value calculation unit is configured to perform spline interpolation using the representative values of the blocks located near a pixel being a calculation target for a low pass component extraction value, to calculate the low pass component extraction value of the calculation target.

  • Publication number: 20130050286
    Abstract: There is provided a driving circuit driving pixels in a display, the pixels each including a liquid crystal cell and a memory. The driving circuit includes: a dividing section dividing one frame period into subfields, the subfields corresponding to respective bits of gray-scale data and having period lengths commensurate with weights of the corresponding bits; a correction section correcting, when bit sequences of two sets of gray-scale data corresponding to two pixels adjacent to each other differ from each other, gray-scale data having a higher gray-scale level out of the two set of gray-scale data, to further increase the gray-scale level thereof; and an ON-OFF period control section controlling a ratio of an ON period or an OFF period to one frame period by bringing the liquid crystal cell of the pixel into an on state or an off state according to a corresponding bit in each of the subfields.
