Abstract: A head-up display includes: display panels, and a light guide configured to direct light from the display panels such that projection positions of images from display regions of the display panels join on the projection target. At least one of time division control and multiple display control is applied to the display panels. The time division control is operation control of the display panels such that the display panels project images at different timings. The multiple display control is operation control of the display panels in which partial regions are set in each display region such that the number of the partial regions corresponds to the number of the display panels, an image is output in one of the partial regions in the display region of each display panel such that the positions of the images projected by the display panels on the projection target differ from one another.

Abstract: A detection device includes a sensor unit, a detector configured to receive an output from a sensor, a detection controller configured to drive and control the sensor unit and the detector, and a processor configured to perform processing in accordance with an output from the detector. The detection controller drives the sensor unit and the detector and determines a touch detection duration in which a coordinate of a finger contacting or nearby the sensor unit is detected, and a fingerprint detection duration in which a fingerprint image of the finger is detected.
