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

Abstract

A camera imaging device using a novel electronic shutter and a shutter imaging method thereof, including a photosensitive device and an image sampling circuit, the photosensitive device includes a photosensitive part and a charge accommodation part connected in parallel with the photosensitive part, and also includes a A short-circuit electronic shutter, the short-circuit electronic shutter is respectively connected in parallel to the positive and negative poles of the photosensitive part and the positive and negative poles of the charge accommodating part, and the photosensitive device is connected to the image sampling circuit for signals. The present invention has simple structure and strong practicability. By setting a short-circuit electronic shutter in parallel inside the photosensitive device, when the present invention is in the standby state, no open-circuit voltage will be generated due to excess charge. Therefore, at the instant the present invention starts, That is, when the short-circuit electronic shutter is disconnected, the sampling voltage generated by the photosensitive device will not be disturbed and the phenomenon of highlight overflow will occur.

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...
