1. A drive control device comprising
circuitry configured to:
determine whether to control light emission of light emitting diodes (LEDs) constituting an LED array in a first mode or a second mode; and
perform light emission control of the LEDs in the determined mode, wherein the circuitry is configured to:
perform light emission control to reduce, from a predetermined number of times, a number of times of repeated light emission of LEDs in one frame to express a gradation of the luminance lower than a predetermined luminance of the LEDs in the first mode; and
perform light emission control for each plurality of the LEDs set as a unit to express a gradation of luminance lower than the predetermined luminance of the LEDs in the second mode,
wherein the circuitry is configured to
perform the light emission control on a basis of a first plurality of bits in bits indicating a gradation of luminance in the first mode; and
perform the light emission control on a basis of a second plurality of bits in the bits indicating the gradation of luminance in the second mode, the second plurality of bits being different from the first plurality of bits.
