Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] The automatic exposure of the camera is based on the pre-determined program by the designer, using the light metering system to measure the intensity of the light at the shooting site, and then automatically selects the appropriate aperture and shutter accordingly to achieve the automatic exposure function. The same principle can be applied to mobile phones with automatic exposure camera function.

[0011] As shown in the attached figure, when the user starts to use the mobile phone, the existing light metering system can be used to measure the light intensity of the environment where the mobile phone user is located. After using the camera integrated on the mobile phone to obtain the external image data and calculate the brightness of the environment, compare it with the preset brightness. If the measured ambient brightness is lower than the preset br...

Abstract

The method includes steps: using automatic photometric system of camera integrated in handset to obtain environment image data, and calculate out brightness of environment; then, comparing environment brightness with preset brightness; if environment brightness is higher than preset brightness, then starting up electricity saving mode of handset; if environment brightness is lower than preset brightness, then closing down electricity saving mode of handset. Using software to control starting up and closing down electricity saving mode of handset automatically, the invention realizes electricity saving for handset without need of adding hardware on handset.

Description

technical field [0001] The invention relates to a power saving method, in particular to a power saving method for a mobile phone with an automatic light metering function. Background technique [0002] At present, there is a trend of multi-functional mobile phones. A mobile phone often not only has the function of calling, but also has multiple functions such as music playback, photography, and games. , automatic focus, anti-red-eye, automatic metering exposure and other functions that were originally only available on high-end digital cameras have also been integrated into mobile phones. However, these various functions integrated on the mobile phone, including the camera function, will consume a certain amount of mobile phone battery power. If these functions are used frequently, the mobile phone battery is easy to run out quickly and needs to be charged, and frequent charging will shorten the time. The lifespan of the phone battery. [0003] To achieve power saving in t...
