Title:
IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/215234
Kind Code:
A1
Abstract:
This image processing device comprises an extraction unit and a prediction unit. The extraction unit extracts, from image data indicating an image acquired by an image capture device and including a plurality of pixels, an unsaturated area in which pixel values are not saturated and a saturated area in which pixel values are saturated. The prediction unit predicts the pixel values of pixels of interest in the saturated area on the basis of the pixel values of boundary pixels of a boundary area in the unsaturated area relative to the saturated area. In this way, the data of an image in which a blown-out highlight has occurred can be used to predict the brightness value of a subject image in the area in which the blown-out highlight has occurred.
