  • Patent number: 8351698
    Abstract: An image processing apparatus generates, for an image, partial histograms by dividing a luminance histogram at downward convex parts of a frequency distribution of the luminance histogram. The image processing apparatus calculates, for a partial histogram selected from the partial histograms, a difference between a maximum frequency in each of all the partial histograms located on the first side of the selected partial histogram, and a minimum frequency within a luminance range from a luminance level of the maximum frequency to that of a maximum frequency in the selected partial histogram as a drop, and sets a maximum one of the drops calculated for the respective partial histograms as a drop. The image processing apparatus sets a weight, which becomes smaller as this drop is larger, for the selected partial histogram, and calculates a weighted average of the luminance histogram, thereby acquiring a luminance value for the tone correction.

  • Patent number: 8350944
    Abstract: A recording mode control circuit controls a first recording mode in which still image data having a first image size corresponding to the number of pixels of an image sensing element is generated and recorded and a second recording mode in which moving image data having a second image size smaller than the first image size is generated and recorded. In generating the moving image data in the second recording mode, a camera signal processing circuit executes electrical zoom processing to obtain the second image size. At this time, a maximum magnification ratio setting circuit sets the maximum variable magnification ratio of electrical zoom processing in the camera signal processing circuit. With this processing, an image recording apparatus which allows a user to select a zoom mode with a small degradation in image quality in electrical zoom processing can be implemented.
