Title:
METHOD FOR DETECTING LUMINANCE LEVEL OF LIGHT FROM HIGH-LUMINANCE LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2023/190620
Kind Code:
A1
Abstract:
The present invention detects the luminance level of light having an intensity exceeding the saturation level of an image sensor. Provided is a method that can be used for detecting the luminance level of light from a high-luminance light source. The method comprises: a step for receiving light from a first light emitting element by means of an image sensor; a step for detecting, in a light reception region in which the light from the first light emitting element has been received, a first saturation region in which the amount of the received light is greater than a saturation level of the image sensor; and a step for determining the size of the first saturation region as a first detection value that represents the luminance level of the light from the first light emitting element.
