Problems solved by technology

[0007] Similar problems may also exist in other image data conversion processes. Since the image data reading and storage are processed by one unit, in order to ensure the integrity of data transmission, the frame interval has to be increased, which in turn leads to a decrease in the frame rate. reduce

Embodiment Construction

[0054] In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0055] Fig. 2 is a structural diagram of an embodiment of the image data conversion system of the present invention. The system connects at least one data sending device and at least one data receiving device. The system includes: an image data reading unit, an image data storage unit, at least two storage units and a first task queue management unit,

[0056] The image data storage unit is used to receive the data source row and column synchronization signal, frame synchronization signal and image data output by the data sending device, send the frame synchronization signal to the first task queue management unit, and use the frame synchronization signal to reset, Utilize the row and column synchronous signal to determine the address...

Abstract

The invention discloses a system and method for converting the image data, in which, the preserving unit of image data send the received synchronized signals of data source frame to the management unit of the first task queue, and sends controlling signals to the management unit of the first task queue after the deposition in each memory cell of image size data. The management unit of the first task queue stores the received signals by turn and provides preserved signals for the image data access unit in accordance with the mechanism FIFO. When completing last operation, the image data access unit resets based on the synchronized frame signal if it accesses the signal from the first task queue, or the image data access unit accesses image data corresponding to preserving unit if it accesses the control signals.

Description

technical field [0001] The invention relates to image data processing technology, in particular to an image data conversion system and method. Background technique [0002] In image compression applications, image display devices usually input images in a progressive scan manner, and the compression algorithm used by image compressors usually operates on a piece of n×m images, where n and m are both positive integers, and n represents The number of columns, m represents the number of rows, so before the image data input by the image display device is transmitted to the image compressor for compression, the image data input row by row needs to be converted into n×m image data unit blocks and output to the image compressor . On the contrary, in the application of image decompression, the decompression algorithm adopted by the image decompressor usually operates on an n×m image, and the output of the image decompressor is also an n×m image data unit block, and the image Displ...
