  • Patent number: 9609297
    Abstract: In an image capturing apparatus, a subject image is converted into an image signal, which undergoes automatic correction processing including white balance correction processing, and further undergoes image quality change processing. A first evaluation value indicating a largest value of an R signal, a G signal, and a B signal of the image signal undergone the image quality change processing and a second evaluation value indicating a luminance of the image signal undergone the image quality change processing are detected. A control evaluation value is calculated using weighted average of the first evaluation value and the second evaluation value according to at least one of an amount of image quality changing effect due to the image quality change processing and a reliability of the automatic correction processing, and exposure control is performed based on the control evaluation value.

  • Patent number: 9402035
    Abstract: A device and method for determining exposure settings in a camera is disclosed. The method comprises capturing an image frame using an image sensor, the exposure of the capturing is based on an initial exposure value setting, determining a temporary exposure value by finding an exposure value that results in a substantially optimum value when applied to a total cost calculation, calculating a saturated pixels cost related to the saturated pixels for the captured image at the temporary exposure value, determining a next exposure value by finding a decrease in exposure value, in relation to the temporary exposure value, for which decrease a change in total cost for non-saturated pixels, in relation to the total cost for non-saturated pixels at the temporary exposure value, is substantially equal to the saturated pixel cost calculated at the temporary exposure value, using this determined next exposure value for capturing a new image frame.
