Abstract

The invention discloses a mobile terminal with an automatic exposure compensation function and an automatic exposure compensation method. The automatic exposure compensation method comprises the following steps of: acquiring the environment brightness, carrying out analog-digital conversion on the environment brightness and storing the converted environment brightness into a buffer module; and extracting environment brightness data in the buffer module, searching a corresponding relation of the environment brightness and an exposure compensation value according to the environment brightness, outputting the corresponding exposure compensation value and carrying out automatic exposure according to an original exposure parameter. According to the invention, in the shooting process, the corresponding exposure compensation value is searched according to the environment brightness and is overlapped on the original exposure parameter to carry out automatic exposure; and the exposure compensation mode has small regulating range and simple implementing process. Moreover, on the premise of not increasing the hardware cost of the mobile terminal, the shooting effect of the mobile terminal is improved and the competitiveness of the mobile terminal in the market is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal with an automatic exposure compensation function and an automatic exposure compensation method. Background technique [0002] With the popularity of mobile terminals, almost everyone has a mobile phone. Yet people hope that more and more functions are integrated on a mobile phone, to increase the practicality and added value of the mobile phone, such as mp3, taking pictures, video recording, etc. have all become common functions of the mobile phone. [0003] At present, different exposure values ​​are usually preset in mobile phones. Each exposure value includes brightness gain value and exposure light value. exposure. When the exposure value is not enough, you can manually adjust the exposure compensation value, such as figure 1 shown. The function of exposure compensation is to increase the exposure value (such as adjusting +1EV, +2EV) when the ambient ...
