Abstract
Definition is calculated for each pixel in a plurality of captured images while changing a focal position. For each coordinates, an image reference value indicating the number of a to-be-referenced captured image is determined. Then, a luminance value is calculated for each coordinates on the basis of the image reference value and the definition. At this time, the luminance value in the captured image indicated by the image reference value of peripheral coordinates is reflected in the luminance value in the captured image indicated by the image reference value of each coordinates. The calculated luminance values are combined to generate an omnifocal image. Accordingly, a smooth omnifocal image is generated. The image reference values themselves are not changed. This prevents unnecessary luminance values of pixels existing in captured images that ought not to be referenced from appearing in the omnifocal image.
