Abstract: An abnormality detection unit according to the invention includes a processor, and a light source device configured to emit light for each of segment periods that are time divided within a frame, and the processor obtains an illuminance value of light emitted into the frame from the light source device after a predetermined delay time has elapsed, whereupon a segment period results where a highest illuminance value is obtained, from a timing of receiving a trigger signal that is in synchronism with the frame, and detects that the light source device is in an abnormal state, when the illuminance value is less than a predetermined threshold.

Abstract: A display control device includes: a receiver configured to receive an image signal; a measurer configured to measure the number of vertical scanning lines and horizontal scanning time of the image signal; a table generator configured to generate a provisional signal table when data measured by the measurer has not been retained in a previously prepared signal table; a detector configured to detect data for regulating an active display region of an image, from the image signal; and an updater configured to update the provisional signal table, based on a detection result by the detector.
