Abstract
An exposure value adjustment apparatus, method, and non-transitory tangible machine-readable medium thereof are provided. The exposure value adjustment apparatus includes a camera module and a processor. The camera module captures a reference image by a base exposure value. The processor generates a histogram of the reference image, divides the histogram into a low partial histogram, a middle partial histogram, and a high partial histogram by a first threshold and a second threshold, decides a high exposure value according to the low partial histogram and the middle partial histogram, decides a low exposure value according to the high partial histogram and the middle partial histogram, and decides a middle exposure value according to the high exposure value and the low exposure value. The low exposure value is lower than the high exposure value, and the middle exposure value is between the high exposure value and the low exposure value.
