Abstract
In an image signal processor with which a group of control variables, having relevance to one another, stored in registers are activated synchronously with the switching of a picture, when a host sets the control variable group in the registers, mutual coherency is secured even if the setting operation extends beyond a pulse of a vertical synchronous signal (VD). In order to realize this, an operation for setting a control variable group in a register block () by the host, and an operation for reflecting the control variable group in a DSP block (), are separately performed. After setting of the control variable group, the host sets H level in a VLAT register (). In correspondence with this operation, a control portion () updates an output of a latch circuit (). As a result, the control variable group is activated from the register block () to the DSP block ().
