Abstract

Disclosed are a method for adjusting an exposure value of an image part on an intelligent terminal and a system thereof. The method comprises the following steps: step 1: opening an image, and marking, on a screen of an intelligent terminal, at least one closed region having an exposure value to be adjusted; step 2: increasing/decreasing the exposure value of the closed region according to a gesture made by sliding a finger on the screen of the intelligent terminal; step 3: after the exposure value of the closed region has been adjusted, saving the image. The present invention solves a problem in which a user is unable to adjust an exposure value of a region when editing an image on a mobile phone. The invention enables a user to self-define selected closed regions and perform exposure adjustment on only one or more of the closed regions, thereby increasing flexibility and practicability.

Background technique

With the development of camera and photo technology, people use a camera, mobile phone and other mobile terminals with camera functions to take photos, recording various beautiful scenes and beautiful moments in life.

In the prior art, when the user uses the mobile terminal to take a picture, generally adjust the focus, exposure time, sensitivity, white balance, etc., and then use the adjusted amount to take a picture, and take a picture with better effect.

When the user edits the photo afterwards, adjusting the exposure of the image is the most frequently used method of retouching. At present, users often adjust the exposure of the picture by the following means: (1) by using the mobile phone to edit the picture to adjust the exposure of the picture; (2) through the third-party library software, such as Meitu Xiuxiu, etc., edit and adjust the exposure of the picture .

However, the exposure of the existing adjustment picture has the following defects: At present, the mobile phone library edits the picture, and the way of adjusting the picture exposure: only the overall exposure of the picture can be adjusted, and the partial area exposure adjustment of the picture is not supported, and the flexibility is insufficient. Therefore, when some scenes need to be adjusted for exposure at a certain position on the picture without affecting the overall exposure, the prior art cannot satisfy the demand. For example, in a photo, the upper left corner needs to be brightened, and the lower right corner needs to be dimmed. The current exposure adjustment method is obviously impossible.
