Backlight detection method, backlight detection device, and imaging camera

摘要

A backlight detection method, a backlight detection device, and an imaging camera that detect backlight in consideration of an imaging state of a subject are provided. For the pixels other than the pixels within the luminance level between the two slice levels given from the outside, the luminance level is integrated to distinguish the object area AR _M from the area HIST _M. It estimates a backlight situation BLS from the area HIST _M Y _M and the brightness level of the subject area AR _M. Thus, the backlight state can be accurately detected.
