Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, PROGRAM, AND IMAGE CAPTURE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/199573
Kind Code:
A1
Abstract:
The present disclosure relates to an image processing device, an image processing method, a program, and an image capture device which make it possible to increase the image quality of an image which is generated using an image obtained in a state with infrared light irradiation and an image obtained in a state without infrared light irradiation.
A modulation coefficient setting unit sets a first modulation coefficient used for correction of infrared brightness information, on the basis of the ratio of infrared brightness information which is brightness information of an infrared image obtained in a state with infrared light irradiation, and visible brightness information which is brightness information of a visible image obtained in a state without infrared light irradiation. A modulation coefficient correction unit corrects the first modulation coefficient into a second modulation coefficient on the basis of a parameter representing the brightness of the subject of the visible image, or the brightness of the photography environment. A brightness correction unit corrects the infrared brightness information using the second modulation coefficient. The present disclosure may be applied to monitoring cameras, for example.
