Title:
An imaging device and a method for controlling the same
Document Type and Number:
Japanese Patent JP6120500
Kind Code:
B2
Abstract:
An image capture apparatus is provided that is capable of accurately determining exposure conditions of multiple images to be used in high dynamic range compositing in a short duration, based on a captured image. A scene dynamic range is computed based on luminance information obtained from an image captured with a standard exposure according to a luminance zone to be prioritized in high dynamic range shooting and luminance information obtained from an image captured with an over-exposure or an under-exposure relative to the standard exposure. An exposure range of multiple images for creating a high dynamic range image is determined according to the computed dynamic range.
