Abstract
Acquiring enough brightness with flash and obtaining an image having a color close to a color which a human senses.An imaging apparatus (10) which emits a flash and photographs an object (20) includes: a lighting unit (11) which emits the flash to the object; an image obtaining unit (12) which obtains continuously-captured images including a first image and a second image by photographing the object (20) while the lighting unit (11) is emitting the flash, the second image having luminance greater than luminance of the first image; a color information obtaining unit (14) which obtains, from the first image, color information of a first color vector; a luminance information obtaining unit (15) which obtains, from the second image, luminance information of a second color vector; and an image generating unit (17) which generates a corrected image by generating a third color vector corresponding to the color information of the first color vector and the luminance information of the second color vector, the corrected image having luminance greater than the luminance of the first image.
