IMAGE PROCESSING APPARATUS, IMAGE PICKUP APPARATUS, IMAGE PROCESSING METHOD, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM

摘要

An image processing apparatus (105) provides reconstruction processing on an input image including parallax images of an object space at different viewpoints and to produce a reconstructed image, and includes a selector (105c) configured to select, from the input image, pixels that have information of an identical region of the object space, a calculator (105d) configured to calculate an average signal value based on signal values of the pixels thus selected, a substitutor (105b) configured to substitute signal values of at least one of the pixels with the average signal value, a producer (105e) configured to produce the reconstructed image from the input image including a pixel whose signal value is substituted with the average signal value, and a determiner (105h) configured to determine whether a first depth of field is smaller than a second depth of field.

1. An image processing apparatus configured to provide reconstruction processing on an input image including parallax images of an object space at different viewpoints and to produce a reconstructed image, the image processing apparatus comprising:
a selector configured to select, from the input image, pixels that have information of an identical region of the object space; a calculator configured to calculate an average signal value based on signal values of the pixels thus selected; a substitutor configured to substitute signal values of at least one of the pixels with the average signal value; a producer configured to produce the reconstructed image from the input image including a pixel whose signal value is substituted with the average signal value; and a determiner configured to determine whether a first depth of field of a synthesized image obtained by synthesizing all parallax images included in the input image with uniform weights is smaller than a second depth of field set to produce the reconstructed image, wherein the selector selects the pixels when the first depth of field is smaller than the second depth of field.
