PURPOSE:To simply perform a processing such as a blink, etc., to only an area to be taken notice of by providing a data switching part for outputting a signal having a large number of bits and varying the output by a time control, etc., between an image memory and a look-up table. CONSTITUTION:With respect to an area to be taken notice of, a data switching part 2 which works as a changeover switch and outputs a signal having a large number of bits is provided between an output of a specific bit of an image data storing part 1 and a look-up table 3. Accordingly, in accordance with an area to which it is desired to perform a processing and the outside of the area, the number of input bits of the look-up table 3 is varied substantially, and also, at the time of the inside of the area, an output of the data switching part 2 is varied by a control from a data switching control part 4. Subsequently, from the look-up table 3 whose contents are set in advance, a signal for executing a blink, etc., is outputted. In such a way, even if the number of bits per one picture element increases and the capacity of the look-up table 3 becomes large, the processing of a blink, etc., can be performed simply with respect to only a necessary area. |
