Picture display device

Abstract

Abstract PURPOSE:To shorten the time required for display of pictures by properly controlling the unit data quantity of a reading process in accordance with the size of the compressed picture data. CONSTITUTION:When the designating and display instructions are inputted for pictures, a control part 9 reads the information on the size of the compressed picture data out of an optical disk 1. Based on this information, a unit data deciding part 10 decides the unit data quantity optimum to the data size and designates this data quantity to the part 9. In this case, the part 9 sets the capacity of a single face of a compressed picture buffer 2 at the value equal to the designated unit data quantity. Then the part 9 performs the control for the parallel execution of the reading, the expansion, and the magnification/ reduction of the compressed picture data respectively. Thus the time required for display of pictures can be shortened.
