PURPOSE:To display the picture profile in the speed corresponding to the television display unit, by performing the address control for memory with the clock signal in synchronizing with the horizontal synchronizing signal and generating the profile signal. CONSTITUTION:When the profile display for the crossing line is designated with the control parameter 100 from computer, the control circuit 10 performs address control 102 corresponding to the picture data 101 to write in the picture data 101 to the memory 20. The clock signal 200 generated in synchronizing with the horizontal synchronizing signal latches the concentration data 103 to the registers 40, 41, 42, and the peofile signal 116 is outputted to each comparator, 50, 51, 52 by comparing the reference concentration signal and the concentration signal. |
