PROBLEM TO BE SOLVED: To reduce capacity of a memory without deteriorating the image quality. SOLUTION: On a screen table TB1 of a pixel 1, the drive pulse width data corresponding to gradation data '0' to '42' need to be stored because the data change, but the drive pulse width data corresponding to gradation data '43' to '255' are not required to be stored, because the data are constant at '255'. Therefore, the table TB1 is constituted of the drive pulse width data corresponding to the minimum gradation value '0' and maximum gradation value '42' of an area, where the output varies and the driving pulse width data corresponding to the gradation data '0' to '42', and accordingly, the data amount of the table TB1 is reduced. |
