Camera imaging device adopting novel electronic shutter and shutter imaging method thereof

Abstract

The invention provides a camera imaging device adopting a novel electronic shutter and a shutter imaging method thereof. The camera imaging device comprises a photosensitive device and an image sampling circuit, wherein the photosensitive device comprises a photosensitive part and a charge accommodation part connected in the photosensitive part in parallel, the photosensitive device further comprises a short circuit type electronic shutter, the short circuit type electronic shutter is respectively connected to positive and negative electrodes of the photosensitive part and the positive and negative electrodes of the charge accommodation part in parallel, and the photosensitive device is in signal connection with the image sampling circuit. The camera imaging device provided by the invention is simple in structure and strong in practicability, the short circuit type electronic shutter is connected in the photosensitive device in parallel, so that when the camera imaging device provided by the invention is in a standby state, no open circuit voltage will be generated by excessive charges, in this way, at the start moment of the camera imaging device provided by the invention, namely when the short circuit type electronic shutter is turned off, the sampling voltage generated by the photosensitive device will not be interfered to generate a highlight overflow phenomenon.

Description

technical field

[0001] The invention relates to an imaging device and an imaging method thereof, in particular to a camera imaging device using a novel electronic shutter and a shutter imaging method thereof. Background technique

[0002] A camera is a device that uses the principle of optical imaging to form an image. The imaging device is a vital core component in the camera, and the shutter is an essential component of the imaging device. There are two kinds of shutters: mechanical shutter and electronic shutter. The principle of mechanical shutter is to use spring or electromagnetic means to control the opening and closing of several blades, or two layers of curtains are left and right or up and down with a certain width like a stage "drawing curtain". The gap "crosses" the window of the imaging image field, allowing the window to get a "opportunity to see light" for a specified period of time; the principle of the electronic shutter is to use the principle that the phot...
