Video taking apparatus and display lightness regulation method

Abstract

The invention relates to an image pickup device, which comprises a memory, wherein the inside of the memory is provided with a built-in table and a brightness adjustment program; the brightness adjustment program is used for adjusting the brightness of a display; the inside of the built-in table is provided with ambient brightness and display brightness which are stored correspondingly; and the brightness adjustment program comprises a parameter preset module, an image acquisition module, an ambient brightness computation module, a comparison processing module, a brightness search module and a brightness adjustment module. The image pickup device can achieve the effect of using lowest screen brightness to make users clearly see images or videos on a screen by utilizing a scene image sensed by the image pickup device to determine the external environment brightness, taking the external environment brightness as a reference of the external brightness, and finding out a corresponding matched screen brightness value, so as to save batteries of the image pickup device when making the users clearly preview simultaneously.

Description

technical field [0001] The invention relates to a photographing device, in particular to a photographing device and a method for adjusting display brightness thereof. Background technique [0002] In the camera system, video is an indispensable item for previewing images on the monitor. However, the monitor screen will appear darker under the sun or in an over-bright environment, making it difficult to see the content of the screen. In general, the user According to the needs of different scene modes, set the required brightness of the display unit in the display menu. The display menu has determined several adjustable brightness ranges before leaving the factory, and the user can choose according to the needs. [0003] However, for some reason, such as continuous shooting in environments with different brightness, there is generally a mismatch between the ambient brightness and the preset brightness in the scene mode preset by the user, which cannot meet the user's preview ...

[0002] In the camera system, video is an indispensable item for previewing images on the monitor. However, the monitor screen will appear darker under the sun or in an over-bright environment, making it difficult to see the content of the screen. In general, the user According to the needs of different scene modes, set the required brightness of the display unit in the display menu. The display menu has determined several adjustable brightness ranges before leaving the factory, and the user can choose according to the needs.

[0003] However, for some reason, such as continuous shooting in environments with different brightness, there is generally a mismatch between the ambient brightness and the preset brightness in the scene mode preset by the user, which cannot meet the user's preview requirements. Increasing the brightness of the display will lead to high power consumption and rapid battery loss
