Abstract: An image processing apparatus which enables natural edge enchantment suited to a frequency band of a subject even when performing local contrast correction in combination with edge enhancement. A local contrast correction unit multiplies a signal of a target pixel in image data by a gain based on values obtained by reflecting signals of pixels around the target pixels.

An edge signal is extracted from the image data and multiplied by a gain based on a signal output from the local contrast correction unit. The edge signal is added to a signal output from the gamma conversion unit.

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.
