Embodiment Construction

[0017] The method for automatic light and shadow adjustment based on a digital camera is special in that it includes the following steps:

[0018] First, the user takes a view through the CCD lens of the digital camera, and at the same time, the liquid crystal display performs a preview of the view. During this period, the light and shadow parameters acquired by the CCD lens can be numerically displayed on the liquid crystal display, so that the user can know the current composition and viewing state in time.

[0019] After that, the user corrects the light and shadow parameters after the final image is formed by manual adjustment. Of course, it can also be that the microprocessor of the digital camera corrects the light and shadow parameters acquired by the CCD lens through preset parameters, so as to realize a relatively simple and fool-like adjustment. In the above process, the light and shadow parameters include light and chromaticity parameters. Moreover, considering th...

Abstract

The invention relates to an automatic light and shadow adjustment method based on a digital camera, which is characterized in that: firstly, the digital camera CCD lens is used to find a view, and a liquid crystal display is used to preview the view. Afterwards, the user corrects the light and shadow parameters after the final image is formed through manual adjustment; or, the microprocessor of the digital camera corrects the light and shadow parameters acquired by the CCD lens through preset parameters. Then, the liquid crystal display simultaneously splits the screen to display the comparison preview of the light and shadow parameters before and after correction; finally, if the user confirms, the shutter is pressed to complete the shooting; if the user does not confirm, it returns to make corrections. In this way, the popular digital camera technology can be used to automatically correct the light and color taken by the picture to form the most perfect digital photo. More importantly, the follow-up cumbersome picture correction work is advanced before shooting, and the operation is simple, which is convenient for users to compose pictures according to their own intentions.

Description

technical field [0001] The invention relates to an adjustment method based on a digital camera, in particular to an automatic light and shadow adjustment method based on a digital camera. Background technique [0002] Photographic technology has been used in our country for a long time, and it is widely used in various industries. Traditional digital photography is based on imaging light that falls on a photosensitive element that is distributed with a large number of pixels. If the light tone ratio in the generated picture is not good, it needs to be modified later according to the software in the computer. These are unavoidably cumbersome for ordinary photographers, and cannot achieve the currently recommended "fool-style" photo effects. Contents of the invention [0003] The object of the present invention is to provide an automatic light and shadow adjustment method based on a digital camera in order to solve the above-mentioned problems in the prior art. [0004] T...
