Abstract: According to an aspect, a detection device includes: photodiodes that are provided on a substrate; light-emitting elements that are arranged so as to face the photodiodes; and a light-transmitting placement substrate that is disposed between the photodiodes and the light-emitting elements and on which target objects are to be placed. The photodiodes, the placement substrate, and the light-emitting elements are arranged in the order as listed, in a direction orthogonal to the substrate. A light-emitting element of the light-emitting elements corresponding to the photodiode to be detected is controlled to be lit, and another light-emitting element of the light-emitting elements corresponding to the photodiode not to be detected is controlled to be unlit. The photodiodes to be detected output sensor values based on light from the lit-up light-emitting elements. The light-emitting elements adjacent to the lit-up light-emitting elements at least in row and column directions are controlled to be unlit.

Abstract: An illumination control device includes a storage that is non-transitory and stores setting information for controlling a light emitter configured to emit light, and a controller that writes the setting information as of then to the storage when a request for writing the setting information is input and reads the setting information from the storage when a request for reading the setting information is input. The light emitter is controlled based on the setting information read by the controller.

Abstract: According to one embodiment, an imaging display system includes an imaging device and a display device, which operate synchronously with each other. The imaging display system includes a control device. The control device is configured to measure light exposure when the imaging device captures an image and determine whether the measured light exposure is insufficient, and control the display device to decrease a refresh rate and the imaging device to prolong an exposure time, when determined that the light exposure is insufficient. The first scanning time for the imaging device to scan the image and the second scanning time required for the display device to scan the display panel are constant.

Abstract: A display system includes a controller and an image display panel. The controller includes a signal transmitter configured to output at least a vertical synchronization signal to a plurality of image-capturing apparatuses; and a synthesizer configured to provide synthesized image signals in units of lines obtained by synthesizing, in units of lines, image signals in units of lines output from the respective image-capturing apparatuses at a timing corresponding to a horizontal synchronization signal formed in a predetermined cycle based on an output timing of the vertical synchronization signal. The image display panel is configured to display sequentially, in units of lines, the synthesized image signals in units of lines.
