Document Type and Number:
Japanese Patent JP5392336
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a well-balanced image between a noise due to a change in sensitivity and a hand shake due to a change in a shutter speed with enough brightness particularly in night photographing through a simple arithmetic processing.SOLUTION: In case of night photographing, a control section 20 first takes an image of a night view by performing a first exposure through an imaging sensor 16 with an open aperture, maximum sensitivity and highest possible shutter speed to avoid a hand shake, and then takes the image of a subject in front of the night view by performing a second exposure through the imaging sensor 16 with minimum sensitivity and maximum luminescence of a flash. A digital signal processing section 28 generates the image for recording by combining the image taken by the first high sensitivity photographing and the image taken by the second flash luminescence photographing in accordance with a predetermined threshold and a predetermined combination ratio (weight) based on a luminescence value of each pixel.
