    Abstract: An image generator configured to generate a face detecting image used in face detection processing of detecting a face from an image, has a representative luminance calculator that calculates a representative luminance value representing a luminance value of each pixel of a photographed image obtained by photographing; and a gamma converter that generates the face detecting image by performing gamma conversion processing on the photographed image. The luminance value of each pixel of the image is converted using a predetermined gamma value. The gamma converter performs the gamma conversion processing using a first gamma value when the representative luminance value calculated by the representative luminance calculator is greater than or equal to a predetermined threshold.

    Abstract: An image processing device selects an image in which sharpness of a photographic subject is relatively high compared with sharpness of a background. The image processing device includes a photographic subject detection unit that identifies a photographic subject region on an image, which includes a predetermined photographic subject, by detecting the predetermined photographic subject from the image, a background region identifying unit that identifies a background region on the image, which is other than the photographic subject region, a sharpness identifying unit that identifies sharpness of the photographic subject region and sharpness of the background region, a score calculation unit that calculates a score based on a difference in the sharpness between the photographic subject region and the background region, and a determination unit which determines the image as an optimum image when the score indicates that photographic subject region is clearer than the background region.
