Light permeable induction electronic type aperture shutter device and its camera

Abstract

The invention relates to a light transmittance inductive electronic device aperture shutter device and a camera. The light transmittance inductive electronic device aperture shutter device comprises an operation and control element, a light metering element and a light transmittance inductive material and is used to control the brightness and transmittance time of the light transmittance inductive material to provide aperture and shutter effect; the light transmittance inductive electronic device aperture shutter device also comprises a control unit which controls the motion of the light transmittance inductive material through the light entering amount measured by the light metering element and / or through the signal of the operation and control element. The camera comprises a lens, an imaging device and a light transmittance inductive electronic device aperture shutter device and controls the image light source from the lens to be imaged on the imaging device. Through a light transmittance inductive electronic device aperture shutter, the invention controls the exposure time and the light entering amount so as to achieve the aperture shutter effect. As the number of components is reduced, the size of the lens can be reduced, and the camera can be lighter, thinner, shorter and smaller; the aperture shutter controls the light entering amount through the overall brightness of the light transmittance inductive electronic material, namely, the light transmittance, so that the operation is simple and easy.

Description

technical field [0001] The present invention relates to an aperture shutter device and a camera thereof, in particular to an aperture shutter made of a light-transmitting sensitive electronic material. The light and shade change is used to control the exposure time and the amount of light to achieve the function of the aperture shutter. The light transmission sensing electronic aperture shutter device and its camera are simple in structure and easy to operate. Background technique [0002] Cameras or video cameras are very common imaging devices in daily life. In photography technology, exposure refers to the amount of light that reaches the film or digital (digital) image sensor. There are two main devices for controlling exposure on the camera: one is the aperture, which controls the opening of the lens to control the size of the light-incoming area; the other is the shutter, which is responsible for controlling the opening time of the aperture to control the exposure time...

AI Technical Summary

Problems solved by technology

The aforementioned aperture shutter device not only has many parts, but also its assembly is complicated; moreover, the heavy and complicated shutter aperture device occupies a huge space and weight, which is not suitable for the current digital (digital) cameras or mobile phone cameras that emphasize lightness. need

[0004] This shows that the above-mentioned existing aperture shutter device and camera thereof obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
