PURPOSE:To obtain high-quality displayed pictures by enabling calculation to be performed by making sufficient allowance for conditions in the past for the heat storage level by feeding back data on heat storage level. CONSTITUTION:A heat storage level arithmetic unit 58, having ROM, serves to calculate heat storage conditions X1 using reference data D1-D11 of 11-bits as an address information. The conditions X1 are calculated with the past heat storage level data HSi-1 of line-1 to be supplied from a heat storage level memory 59 in the arithmetic unit 58 to obtain heat storage level data HSi of the present line. The data HSi is sent out as heat storage level data HSi-1 by being delayed for line-1 by the memory 59 and also supplied to an applied energy arithmetic unit 57 for calculation of applied energy. The memories 58 and 59 make up a loop circuit, and the data HSi-1 are fed back to the arithme tic unit 58. Calculation can thus be made by making dufficient allowance for the past heat storage conditions by the arithmetic unit 58. |
