A method for selecting metering mode and an image capturing device thereof are provided. The method includes: obtaining a first exposure compensation value, a first white balance compensation value and a first focus distance corresponding to a first image; determining whether a first color temperature corresponding to the first white balance compensation value is greater than a predetermined color temperature; if yes, determining whether an ambient brightness corresponding to the first exposure compensation value is greater than a predetermined brightness, and if yes, setting a metering mode to be an average metering mode, while if not, setting the metering mode to be a center-weighted average metering mode; and if not, determining whether the first focus distance is greater than a predetermined focus distance, and if yes, setting the metering mode to be the center-weighted average metering mode, while if not, setting the metering mode to be the spot metering mode.

An image display method, adapted to an electronic device having a screen, an image capturing unit, and a light sensor, includes the following steps. A preview image captured by the image capturing unit is received and processed so as to generate a plurality of pixel luminance values of the preview image. A light illumination of an ambient light detected by the light sensor is received. An output Gamma lookup table among a plurality of Gamma lookup table is selected according to the pixel luminance values and the light illumination of the ambient light. An adjusted pixel luminance value corresponding to each of the pixel luminance values is generated based on the output Gamma lookup table so as to accordingly display the preview image on the screen with sunlight readability. An electronic device is further provided in the invention to implement the above method.


In a wireless communication system, a user equipment is configured to establish an RRC link with a cell when operating in a first mobility state or a second mobility state of an RRC connected mode. When all currently running application programs only cause background traffic or do not require short data latency, the user equipment is configured to maintain in or switch to the first mobility state having a lower monitoring frequency. When any of the currently running applications involves user interaction or requires short data latency, the user equipment is configured to maintain in or switch to the second mobility state having a higher monitoring frequency.


An auto-focus compensation method, adapted to an image capturing device having a touch screen, includes the following steps. First, a first touch operation performed on a first object displayed on the touch screen is detected. Next, an auto-focusing procedure is performed so as to obtain a focused image. A staying time of the first touch operation on the first object is accumulated and determined whether it exceeds a time threshold. When the staying time exceeds the time threshold, an adjustment interface is displayed on the touch screen, and a second touch operation performed on the adjustment interface is detected. The focused image is adjusted according to the second touch operation, and a new focused image is thus obtained and captured. An image capturing device is also provided in the invention to implement the aforementioned auto-focus compensation method.
