摘要： A digital camera (10a) is placed in any of three photographing modes labeled a “narrow mode”, a “normal mode”, and a “wide mode”. An operating point setter (903) variably sets an operating point of a CCD (26) defining a brightness range of a subject which falls within a dynamic range of an image sensor, based on a photographing mode as set. A LUT setter (902) variably sets a gradation correction LUT which is a concrete representation of gradation correction characteristics in gradation correction performed by a γ correction circuit (55) (characteristics in γ correction), based on the photographing mode as set. The operating point set by the operating point setter (903) and the gradation correction LUT set by the LUT setter (902) are changed in synchronism with each other in accordance with change in the photographing mode.

摘要： A set value input screen used for a user to input set values is displayed on a display unit for parameters when a manual setting mode is set. A list box of the set value input screen is for designating an arbitrary object to be set out of the parameters, and a graph display-input portion displays a graph representation of initial values of the set value at a plurality of points of time set beforehand and having specified intervals therebetween for the parameter selected in the list box. Data points at the respective points of time are movable by an input unit and the set values corresponding to the data points can be changed by moving the data points. There can be provided highly versatile image processing apparatus and image processing program matching human visual characteristics while preventing or suppressing a cost increase and a larger-scale construction.

摘要： In a digital camera 1, an interchangeable lens 3 is attachable to a camera body 2, and a lens ROM 30 is provided in the interchangeable lens 3. In the lens ROM 30, an ICC profile which is color compensate information particular to the interchangeable lens 3 is recorded. When photographing is performed with the interchangeable lens 3 attached, the ICC profile is associated with the obtained image data. Consequently, color compensate information can be set for each kind of interchangeable lens, so that color compensation reflecting the characteristic of the interchangeable lens can be appropriately performed on the image data.
