Title:
IMAGING DEVICE AND IMAGING DEVICE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2019028378
Kind Code:
A
Abstract:
To provide an imaging device that determines a light metering area on the basis of brightness of an entire imaging screen or a depth of a main subject and a background, and can conduct main light emission with respect to the main subject with a proper amount of light.SOLUTION: An imaging device, which causes light emission means to conduct pre-light emission ahead of main light emission, has: luminance information acquisition means that acquires first luminance information obtained upon non-light emission of the light emission means, and second luminance information obtained upon pre-light emission of the light emission means; computation area determination means that determines a computation area of the main light emission; and main light emission-amount determination means that determines an amount of light emission of the main light emission from a light metering result obtained in the computation area of the main light emission. The computation area determination means is configured to calculate a weighted value based on luminance from the first luminance information; calculate a weighted value based on a depth of an entire screen from differential information between the first luminance information and the second luminance information; and calculate the computation area to be used in computation of determining the amount of light emission of the main light emission on the basis of the weighted value based on the luminance and the weighted value based on the depth.SELECTED DRAWING: Figure 1
