Abstract: This specification discloses a method that uses three-dimensional image interpolation algorithm implemented in an image player to solve the problem of frame rate conversions between output contents and the image player. It aims to achieve high resolutions and high frame rates. The disclosed method adjusts the frame resolution and frame rate of the received image data according to the playing format of the image player. That is, the pixel values contained in a frame are interpolated to generate several interpolated pixel values in order to fit with the frame resolution. The interpolated frame is then stored. The next two consecutive frames are further extracted. The central position is determined according to the frame playing frequency. The corresponding pixel values of the two consecutive frames are used to produce several interpolated pixel values. The interpolated pixel values form an interpolated frame, which is then saved.

Abstract: A method for compressing and decompression digital image data. When compressing, the method begins by choosing a reference row. The relative data between the reference row and the current row is compared to search for the differential data set. The largest matching data set of the differential data set is searched starting from the starting position of the last differential data set. According to the matching conditions, the data type of the to-be-compressed data is first verified, then the to-be-compressed data set type and its relative referencing value are verified. Finally, the relative coding process is started. This process has a higher compression ratio and decompression speed, and increases the compression speed dramatically.

Abstract: This specification discloses a method of using locality statistics characteristic to enhance gamma corrections. Using the property that the color values of nearby digital image pixels are close to one another, the cache queue operation model is employed to partly replace the time-consuming table mechanism in the gamma correction procedure. The disclosed method first establishes a cache queue and then captures digital image pixels. According to the extracted digital image pixels, gamma correction values are searched to satisfy the cache queue. Finally, the gamma correction values corresponding to the digital image pixels are stored.

Abstract: Pixel information of a current block is correlated with pixel information of a reference frame indicated by a first motion vector of a block proximate to the current block, pixel information of the reference frame indicated by a second motion vector of a block of the reference frame spatially coincident with the current block, and pixel information of predetermined regions of the reference frame. At least one of the first, second, and third motion vectors having the lowest cost function is selected as a candidate motion vector. Pixel information of the current block is correlated with pixel information of regions offset from the regions indicated by the candidate motion vectors to determine refined candidate motion vectors and corresponding refined cost functions. The refined candidate motion vector having the lowest refined cost function is selected as the motion vector of the current block.
