Patent ID: 7164442

Claim:
An image control device for controlling input image data, executing signal processing with controlled image data, and outputting processed image data in accordance with a preselected standard, said device comprising: a memory for storing the input image data; a standard adjusting circuit for storing the image data read out of said memory therein and outputting stored image data at a timing matching with the preselected standard; a memory control circuit for controlling at least said memory and said standard adjusting circuit, said memory control circuit controlling input and output of the image data from said memory, setting a unit amount of continuous image data to be handled together at the time of output, setting a unit number of image data for a single line and consisting of unit amounts of continuous image data, and outputting a request for an access to said memory to thereby control read-out; a communicating circuit for selectively sending or receiving the image data; an image correcting circuit for analyzing, when the image data read out of said memory are smaller in amount than the unit number of image data, particular information particular to said image data and relating to display, and executing, based on a result of analysis, at least one of restoration and processing with each unit image data of divided image data; an instruction information feeding circuit for encoding the particular information and feeding encoded particular information to said image correcting circuit; a display adjusting circuit for adjusting, based on a condition input in accordance with a combination of luminance data and color data constituting the image data read out of said memory, a sampling order and controlling feed of the unit number of image data; and an arbitrating circuit for giving the highest degree of priority to an access for refreshing said memory, and arbitrating an access request for control data, which differs from the image data, with respect to a remaining accessible time when said image data are output, wherein said display adjusting circuit comprising a size controlling circuit for controlling, when supplied with valid pixel number information representative of a number of pixels to be actually used for display and independent of a data size whose unit is the unit amount of image data, output of image data short of the unit number of image data on the basis of said number of pixels or controlling, based on said data size, delivery of said unit number of image data on a single line, and delivering controlled image data to said memory, wherein said communicating circuit comprises an interface for interchanging the image data with a unit located outside of said device, and wherein said image correcting circuit and said instruction information feeding circuit precede said standard adjusting circuit.
