Abstract

PURPOSE:To enable a modification control simply as desired even during a cross operation by stopping operational means' outputs which are inputted to desired channels in a second memory means and next by changing corresponding memory data to be transferred to a first memory means. CONSTITUTION:When modification is desired during a cross operation, flags are raised in memory regions corresponding to channels selected from memory regions M31 to M3n in a memory circuit M3, and these flags are used to interrupt outputs of from the memory circuit M2 by transistors corresponding to channels selected from transistors Tr1 to Trn which compose a switch 7. Further a changeover operation of a switch 11 which realizes the composition of a multiplexer or the like is performed according to an output of a modifying wheel 12 so as to rewrite light regulation levels of channels selected in a memory circuit M4. The light regulation levels of the selected channels, memorized in the memory circuit M4, are modified by operating the correction wheel 12. Modifying controls can be thus performed even during a cross operation similarly with during a non-cross operation.
