[Prior Art] With the development of multimedia and network technologies, high-definition digital cameras have gradually become the standard equipment for mainstream mobile communication devices. At this time, in addition to the improvement of the element, the imaging quality, situation mode, and manual function of the digital camera have been gradually improved and improved. Nowadays, the use of mobile communication devices (ie, mobile phones) has become a very practical function. In order to get a satisfactory photo, one of the most basic conditions is the exposure accuracy. Under the premise of the same sensitivity, the amount of exposure is determined only by the shutter value and the aperture value. The two are mutually constrained. When the amount of exposure is insufficient, increasing the aperture value or lowering the shutter value can increase the exposure amount. In the current mobile communication device with digital camera function, the metering method uses the reflective photometer to measure the light intensity, and the reflective photometer measures the intensity of the light reflected by the object; however, the reflective photometer Generally, only multi-zone average metering is performed. In a complicated light environment (such as backlighting, lighting, etc.), it may cause inaccurate metering. For example, 'because most of the reflective photometers have wide measurement angles, Therefore, when the subject is particularly bright or extremely dark, the reflective photometer will provide incorrect and inappropriate exposure data, resulting in underexposure or overexposure during shooting. Therefore, how to provide a 1261460 mobile communication device and its imaging method to provide a more accurate exposure data to avoid underexposure or overexposure during shooting is one of the important topics in the current mobile phone industry.
