Abstract:
1. An image processing apparatus including a generation unit configured to generate a high dynamic range (HDR) image by combining N (N is an integer not less than three) images captured by a capturing unit with N different exposure values, the apparatus comprising: a capturing control unit configured to cause the capturing unit to capture two images with two different exposure values; a conversion unit configured to convert a tone characteristic of at least one of the two images; and a generation control unit configured to cause the generation unit to combine the two images, the tone characteristic of at least one of which has been converted by said conversion unit, wherein said conversion unit converts a tone characteristic of at least one of the two images, based on the N exposure values and the two exposure values of the two images, such that a tone characteristic of an HDR image generated from the two images is approximated to a tone characteristic of an HDR image generated from the N images.
