  • Patent number: 7474316
    Abstract: A dithering pattern that is generated based on a spatial operation is used for a Bit-Depth Extension (BDE) technique for preventing contouring artifacts in an image displayed by a display having a bit-depth that-is less than the bit-depth of the image. The dithering pattern can be based on achromatic visual model or a spatio-chromatic visual model. The dither pattern is formed by shaping a pseudo-random noise signal by an equivalent noise visual model that is based on an array of pixels. Alternatively, the array of pixels is based on an image, or a determinate array of pixels.

  • Publication number: 20090002763
    Abstract: An image processing apparatus (information processing apparatus) is capable of storing image data (data) generated by reading a document image into a storage device (storage medium) such as a USB memory. When the storage device cannot store the image data due to a shortage of capacity, the image processing apparatus transfers the image data to a transfer destination indicated by transfer destination information stored in the storage device, and stores the image data in the transfer destination. The transfer destination of the image data is a storing section in the image processing apparatus, or a PC (storage apparatus) etc. connected to the image processing apparatus through a communication network.

  • Publication number: 20090002298
    Abstract: A display apparatus includes a luminance compressing section, a luminance extending section, and a W calculating section. The luminance compressing section subjects three color signals to luminance compression according to a luminance in a preceding frame, and outputs compressed color signals. The luminance extending section outputs luminance extended and converted color signals of respective three colors. Each of the luminance extended and converted color signals is obtained by subtracting a corrected minimum luminance value from a luminance extended color signal which is obtained by subjecting the compressed color signal to luminance extension at a luminance extending rate S in accordance with a function F(t). The function F(t) has as a variable a ratio t of a minimum luminance value to a maximum luminance value of the compressed color signals. The corrected minimum luminance value is obtained by multiplying the minimum luminance value by a coefficient k.
