Zusammenfassung: | A distance acquisition method comprising: initializing an optical ranging system, the optical ranging system including a plurality of pixels operable to covert incident light to electrical charges; collecting electrical charges with the plurality of exposed pixels over an integration time, each pixel collecting electrical charges with an amplification and a sensitivity; correlating the electrical charges collected in each pixel to an exposure value for each pixel, the exposure value corresponding to being adequately exposed, over-exposed, or under-exposed; identifying each exposure value for each pixel as being either valid or invalid, wherein a valid exposure value corresponds to an adequately exposed pixel and an invalid exposure value corresponds to an over-exposed or under-exposed pixel; totalling the number of valid exposure value pixels; totalling the number invalid exposure value pixels; determining an exposure ratio, the ratio being the number of pixels with valid exposure values divided by the number |
