Title:
IMAGING APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2015118320
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To accurately detect a high-luminance area other than a main subject, to perform appropriate exposure control on the main subject.SOLUTION: An imaging apparatus includes: a photometric section 111 which divides an input image into a plurality of areas and acquires a photometric value for each of the areas; an EV value calculation section 112 which calculates an EV value for each of the area, on the basis of the acquired photometric value, to determine whether the calculated EV value is smaller than a predetermined threshold, for each of the areas; and an evaluation value calculation section 114 which detects a maximum luminance area having the highest luminance value, in the areas determined to have an EV value smaller than the threshold, and calculates an evaluation value to be used for at least one of exposure control, white-balance control, focus control, and grayscale control in capturing an input image, on the basis of the photometric value of the detected maximum luminance area. The photometric value of an area having an EV value equal to or larger than the threshold is not used for calculating the evaluation value.
