Abstract

An image capturing device includes a plurality of light emitters, an image capturer, a memory and a processor. The memory stores a target brightness value. The processor controls the light emitters to emit light and controls the image capturer to capture an image. The image is divided into a plurality of areas and the light emitted by each of the light emitters corresponds to one of the areas. The processor calculates a current brightness value of each area and calculates an absolute difference between the current brightness value of each area and the target brightness value. The processor determines whether each absolute difference is larger than a first threshold. According to a determination result, the processor adjusts an exposure parameter of the image capturer or adjusts a light emitting intensity of the light emitter corresponding to the area with the absolute difference larger than the first threshold.
