Abstract

The invention discloses a photographing method and device and a mobile terminal. The method includes acquiring a preset commissioning constant that the initial exposure target value under the current scene corresponds to; determining that the product of the preset commissioning constant and the initial exposure target value is the novel exposure target value under the current scene; utilizing the novel exposure target value to photograph the object. By means of the method and the device, the new exposure target value is the value modulated through the preset commissioning constant, the photographing effect is better compared with the original effect, and photographed image is clear in detail, and the problem of poor image effect caused by the fact that the exposure target value cannot be changed according to different brightness environments due to the fact that the photographed image effect cannot reach a balance point due to the fact that the bright-dark difference is too large is solved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a photographing method, device and mobile terminal. Background technique [0002] The current mobile phone camera will use touch AE (touch automatic exposure) for exposure. The principle is to use the user's finger to touch the screen area to select the subject, trigger the metering, use the sensor sensor to sense the brightness of the subject, and according to the sensing result Different exposure time, gain value, and f-stop are used to make the picture reach a brightness that is comfortable for the naked eye. For example, for a scene with a very bright sky, the details of the sky and clouds can be clearly seen in the captured image by reducing the exposure time, reducing the gain value, and reducing the aperture size. In the same way, for dark places, the brightness of the image can also be improved by changing these three coefficients. In general, if the final brightness...
