Embodiment Construction

[0080] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0081] The terms of the present invention are explained as follows:

[0082] Exposure: refers to the amount of light entering the camera lens and illuminating the photosensitive element during the shooting process, which is controlled by the combination of aperture, shutter, and sensitivity.

[0083] Exposure time: Exposure time mainly refers to the photosensitive time of the photosensitive device. The longer the exposure time, the br...

Abstract

The embodiment of the invention provides an exposure time adjusting method applied to a camera. The method comprises the steps: determining the movement speed of a shooting target; determining a firsttime parameter according to the movement speed; wherein the higher the movement speed is, the smaller the first time parameter is; and adjusting the exposure time of the camera according to the determined first time parameter. By applying the exposure time adjusting method and device provided by the embodiment of the invention, the exposure time of the camera can be adjusted in the process of shooting the image by the camera, and the definition of the image acquired for the moving target is improved.

Description

technical field [0001] The present invention relates to the technical field of cameras, in particular to a method and device for adjusting exposure time, and a camera. Background technique [0002] Currently, the exposure time of the camera is usually set to 40ms. However, for a moving target, the relative displacement between the moving target and the camera is relatively large within the normal exposure time of 40 milliseconds, which results in poor image definition of the moving target captured by the camera. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present invention is to provide an exposure adjustment method and device, and a camera, so as to improve the clarity of an image collected for a moving target. [0004] The specific technical solutions are as follows: [0005] A method for adjusting exposure time, applied to a camera, the method comprising: [0006] Determine the movement speed of the shooting target; [0007] Determine a f...
