  • Publication number: 20200013825
    Abstract: The present disclosure relates to an imaging device and an electronic device that make it possible to obtain a better pixel signal. A photoelectric conversion part that converts received light into a charge; a holding part that holds a charge transferred from the photoelectric conversion part; and a light shielding part that shields light between the photoelectric conversion part and the holding part are provided. The photoelectric conversion part, the holding part, and the light shielding part are formed in a semiconductor substrate. The light shielding part of a transfer region that transfers the charge from the photoelectric conversion part to the holding part is formed as a non-penetrating light shielding part that does not penetrate the semiconductor substrate. The light shielding part other than the transfer region is formed as a penetrating light shielding part that penetrates the semiconductor substrate. The present technology is applicable to an imaging device.

  • Patent number: 10469783
    Abstract: To transfer all charges retained in a charge retention region. The photoelectric converter generates a charge corresponding to the exposure amount during a predetermined exposure period. The generated-charge retention portion and the output charge retention portion retain the charge. The generated-charge transfer portion transfers the charge from the photoelectric converter to the generated-charge retention portion to perform the generated-charge transfer after the elapse of the exposure period. The retained-charge transfer portion transfers the charge retained in the generated-charge retention portion to the output charge retention portion to perform the retained-charge transfer.

  • Patent number: 10410423
    Abstract: An HUD superimposes a display object, as a stereoscopic image or a planar image, on an actual scene. A display control device acquires information about a moving object and information about surrounding and estimates a relative distance between a display obstacle and the moving object. When it is determined that the display obstacle exists or can exist between the display object and the moving object, the display control device changes the display mode of the display object in accordance with the amount of change in the relative distance and notifies the HUD of the display mode.
