DIGITAL CAMERA

摘要

A solid-state imaging device has normal pixels, first phase difference pixels, and second phase difference pixels. “R”, “G”, and “B” denote colors of color filters provided for the respective pixels. A color dependence characteristic calculator averages output signals from the normal pixels located at the center of a screen, on a color basis, and thereby calculates average output signals. A color determination section determines a main color of a subject, out of three primary colors, based on the average output signals. An AF controller performs focus adjustment of a taking lens based on the output signals of the determined main color, out of the output signals from the first phase difference pixels and the second phase difference pixels.

主权项

1. A digital camera comprising:
a taking lens for forming an image of a subject; a solid-state imaging device having an imaging surface on which three types of pixels are arranged, the three types of pixels being a plurality of normal pixels having sensitivity not dependent on an incident direction of light, a plurality of first phase difference pixels highly sensitive to light of a first incident direction, and a plurality of second phase difference pixels highly sensitive to light of a second incident direction opposite to the first incident direction, the each pixel having a color filter of one of at least three primary colors; a color dependence characteristic calculator for performing calculation of one of or both of output signals from the normal pixels and output signals from the first and the second phase difference pixels, on a color basis, to calculate a color dependence characteristic of the output signal, after a color image of the subject is captured; a color determination section for determining a specific color based on the color dependence characteristic; an autofocus detector for obtaining a focus adjustment amount of the taking lens based on the output signal from the pixel having the color filter of the specific color, out of the first and the second phase difference pixels; and a focus mechanism for setting the taking lens to an in-focus position in accordance with the focus adjustment amount.
