Abstract: An image processing apparatus, method and computer program product, wherein a luminance histogram of input image data is generated by the histogram generating section and a polarization degree of the luminance histogram is evaluated by the polarization degree evaluating section in order to determine whether the input image data is in a true backlight condition or in a halation condition. An optimum dynamic range correction and tone curve correction are performed on the input image data based on a result of the above-described determination.

Abstract: It is an object of the present invention to provide a camera apparatus which can reduce processing time by simplifying image processing in areas of small importance and by taking advantage of the fact that the image data is acquired by a camera.

Abstract: An image processing apparatus, which includes an input unit inputting a color signal of a color space, a designating unit designating a color range according to the input color signal, a black amount determining unit determining an amount of black for the input color signal by referring to a black generation condition corresponding to the designated color range, wherein the designated color area is an area where a difference between a maximum amount of black and a minimum amount of black is small.

Abstract: An image processing apparatus includes a determination part, an information obtaining part, a dynamic range setting part and a processing part. The determination part determines whether or not an image includes an area where destruction of gradation due to contrast correction tends to be conspicuous. The information obtaining part obtains information of the area when the determination part determines that the image includes such an area. The dynamic range setting part sets a dynamic range using the information obtained by the information obtaining part. The processing part performs the contrast correction on the image using the dynamic range set by the dynamic range setting part.

Abstract: A subject area extracting unit extracts a main-subject area from the color image data; a correction amount calculating unit calculates a gradation correction amount based on the information on the thus-extracted main-subject area; a control zone extracting unit extracts a predetermined control zone from a brightness zone to which the main-subject area does not belongs; a determining unit determines whether or not the gradation correction amount on the control zone should be controlled, according to a predetermined control requirement; and a control unit controls the gradation correction amount according to the determination result of the determination unit.
