Image processing apparatus

An image processing apparatus, comprising;

• acquiring means for acquiring image data of a plurality of first images to be synthesized that are obtained by taking a single scene under different exposure conditions;
• synthesis means for synthesizing said image data of said plurality of first images obtained by said acquiring means to generate synthesized image data of a composite image;
• and
• image processing means for subjecting the synthesized image data of said composite image by said synthesis means to dodging processing,
• wherein said synthesis means sets synthesis conditions of image synthesis using said image data of said plurality of first images, and synthesizes said image data of said plurality of first images using said set synthesis conditions.

An image processing apparatus, comprising:

• acquiring means for acquiring image data of a plurality of second images obtained by taking a single scene under different exposure conditions;
• selection means for selecting a plurality of optimal first images for synthesis among said image data of said plurality of second images obtained by said acquiring means;
• and
• synthesis means for synthesizing image data of said plurality of the optimal first images selected by said selection means to generate synthesized image data of a composite image,
• wherein said synthesis means sets synthesis conditions of image synthesis using said image data of said plurality of first images, and synthesizes said image data of said plurality of first images using said set synthesis conditions.

• wherein said synthesis means
• performs said image synthesis after converting said image data of said plurality of first images to subject luminance data of logarithmic scales,
• sets said synthesis conditions as shifting amounts of the subject luminance data of respective images from the subject luminance data of one image among said plurality of first images, as well as,
• determines logarithmic values of the shutter speeds and the aperture sizes of the stop when said one image and said respective images were taken respectively, calculates each first difference between each of the determined logarithmic values of the shutter speeds when said respective images were taken and each of the determined logarithmic values of the shutter speeds when said one image was taken, and each second difference between each of the determined logarithmic values of the aperture sizes of the stop when said respective images were taken and each of the determined logarithmic values of the aperture sizes of the stop when said one image was taken, and adds said each first difference and said each second difference for said respective images to calculate the shifting amounts of the respective images.
