Abstract
A liquid-crystal-device control circuit includes pixels corresponding to intersections between scanning lines in rows and data lines in columns, a counter that counts the number of horizontal lines included in a video signal supplied correspondingly to a region broader than pixels corresponding to the scanning lines in the rows, a determination circuit that determines which is greater between the number of horizontal lines counted by the counter and a value stored in a predetermined register, an addition/subtraction circuit that, depending on a result of determination by the determination circuit, adds a predetermined number to or subtracts the predetermined number from the value stored in the register, and a scanning control circuit which stores the value obtained by the addition/subtraction circuit in the register, and which defines start timing of the second field on the basis of the value stored in the register.
