1. A control device for use in a case where frame periods, each being a period in which one image continues to be displayed, vary in length within a given range or temporarily become stable in length on a frame-by-frame basis, and accurate lengths of the frame periods are not known beforehand,
the control device changing a total number of subframe periods to reconfigure the frame period with n subframe periods, where n is an integer of two or more, regardless of the frame period input, and causing the display of the image,
the control device comprising:
a signal processor that outputs an output video signal according to a first input video signal on a subframe-period-by-subframe-period basis; and
a controller that supplies the output video signal output from the signal processor and a control signal for controlling an operation of the display panel to the display panel,
wherein each of the n subframe periods has a same predetermined length and a same predetermined duty cycle.
