Data processing apparatus for decoding, converting in size and coding

Abstract

A data processing apparatus consists of an input buffer for storing one or more pieces of line data which each are formed of pieces of picture data and adding a specific code to each of the line data, a searching section for searching the input buffer for one or more specific codes, a search control section for (1) calculating a number Dx of pieces of picture data stored in the input buffer, (2) instructing the searching section to search the input buffer for one or more specific codes when the number Dx reaches a reference number, (3) repeatedly adding an incremental value to the reference number to increase the reference number in cases where no specific code is found out by the searching section, and (4) repeatedly instructing the searching section to search the input buffer for one or more specific codes when the number Dx reaches the reference number increased until at least one specific code is found out by the searching section, a data taking out section for taking out one or more pieces of line data stored in the input buffer in cases where at least one specific code is found out in the input buffer by the searching section.
