Title:
電子カメラ
Document Type and Number:
Japanese Patent JP5263764
Kind Code:
B2
Abstract:

To improve performance for reflecting a result of white balance adjustment set before photographing, at the time of photographing.

The electronic camera is provided with: an amplifier for amplifying an object image signal; a gain information calculator for calculating gain information indicating a gain given to a color information signal on which a white balance adjustment is made, in the state where an object signal is amplified by giving a predetermined amplification factor from the amplifier based on the gain given to the color information signal obtained by performing the white balance adjustment using the object image signal; a storage for storing the gain information calculated by the gain information calculator; a detector detecting a difference between the amplification factor given from the amplifier to the object image signal at a time of photographing and the predetermined amplification factor; a corrector for correcting the gain information stored by the storage based on the difference detected by the detector; and an adjustor for adjusting the color information signal at the time of photographing by using the gain information corrected by the corrector.
