Abstract:
1. A moving picture encoder device for encoding moving picture data, comprising: a search unit for performing a search of a reference pixel block from among pixel blocks in a reference frame for each of target pixel blocks in a target frame, the reference pixel block having a sum of differences between corresponding pixel data smaller than a predetermined threshold, the reference pixel block being searched by comparing the sum of the differences of each of the pixel block in the reference frame with the predetermined threshold; a search time setting unit for determining a specific time period which is assigned to each of the target pixel blocks for the search of a reference pixel block by the search unit; and a search time controlling unit for counting a time elapsing from beginning of the search of a reference pixel block as a time period consumed by the search and stopping the search at the time when the time period consumed by the search of the search unit reaches the specific time period, wherein: when the search is stopped by the search time controlling unit, the search unit selects a pixel block with which the sum of the differences is minimum from among the previously searched pixel blocks as a reference pixel block of a search result, and when a reference pixel block with which the sum of the differences is smaller than the predetermined threshold is found before the end of the specific time period, the search unit stops the search for the reference pixel block and selects the reference pixel block as the reference pixel block of the search result for the target pixel block, and the search time setting unit allocates a difference between the specific time period and the time period consumed by the search of the reference block to a search as to another target pixel block.
