Claim Text:
1. An electronic apparatus, comprising: a camera module, being enabled into a High Dynamic Range (HDR) mode and configured to capture a first reference frame according to a first exposure setting, wherein the first reference frame corresponds to a plurality of first luminance values; and a processor, being electrically connected to the camera module and configured to divide the first reference frame into a plurality of blocks, calculate an average luminance value for each of the blocks, wherein each of the average luminance value is one of the first luminance values of the first reference frame, wherein the processor further adjusts at least a portion of the average luminance values that are greater than a predetermined threshold before calculating a first weighted luminance value, calculates the first weighted luminance value of the first reference frame by averaging the average luminance values of the blocks, generates a first comparison result by comparing the first weighted luminance value and a luminance target of the HDR mode, and decides a second exposure setting according to the comparison result.
