    Abstract: An image processing apparatus which may include a grayscale modulator forming a ?? modulator. The modulator may include an adder that adds the pixel value of an image and an output of a feedback arithmetic unit, a quantizing unit that quantizes an output of the adder and outputs a quantized value including a quantization error as the result of ?? modulation, a subtractor that calculates the quantization error, and the feedback arithmetic unit that filters the quantization error and outputs the filtering result to the adder. The filter coefficient of filtering by the feedback arithmetic unit may be determined such that the amplitude characteristics of noise shaping by the ?? modulator in a frequency band that is equal to or more than an intermediate frequency band are the inverse characteristics of the spatial frequency characteristics of the human eye.

  • Patent number: 8436921
    Abstract: A picture signal processing system includes a playback apparatus and a display apparatus connected via first and second communication units. The playback apparatus receives a video signal made up of source data generated by moving giant image data in a constant direction at a constant speed, wherein the giant image data has a number of pixels far greater than the number of pixels in a display region. The playback apparatus reads source data speed information stored in the video signal header, and transmits the video signal and the speed information to the display apparatus. The display apparatus references a table to determine how to process the video signal on the basis of the speed information, processes the video signal, and then displays the processed video signal.

  • Patent number: 8095864
    Abstract: An electronic apparatus capable of displaying linked pages in turn by an easy operation for users is provided. In a <body> element in an SMIL document, the attribute ??dur=t is added to URI description for specifying a media element. The resulting notation implies that a file name placed before ?? indicates a designated page and a link destination of the designated page is displayed. A numerical value following dur= indicates the duration for which a given link contained in the designated page can be activated. An SMIL player interprets an SMIL document having such a description, so as to allow auto-linking to the link destinations of the designated page with the defined link intervals.

  • Publication number: 20100079483
    Abstract: An image processing apparatus prevents the inappropriate application of error diffusion and adaptively applies palette conversion functions according to the properties of the source. A processing subsystem performs various processing with respect to an original video source. A palette converter converts the palette bit depth, having modifiable palette conversion functions for creating the illusion of expressing the pre-conversion palette tones in the post-conversion image. A controller turns on the palette converter, turns off the palette converter, or modifies the palette conversion functions thereof, in accordance with at least original source information and system-wide settings information.
