Title:
カラー画像の拡張方法並びにその方法の実行機構
Document Type and Number:
Japanese Patent JP6803355
Kind Code:
B2
Abstract:
A method of producing color images of a scene captured by an image sensor exposed to visible light as well as IR radiation, the method comprising:
- capturing a first image with a first proportion of an iris aperture covered by an IR-cut filter,
- determining a first amount of radiation captured in the first image,
- capturing a second image with a second proportion of the iris covered by the IR-cut filter,
- determining a second amount of radiation captured in the second image,
- calculating a proportion of IR radiation in the scene based on the first amount of light, the second amount of light, the first IR-cut filter proportion, and the second IR-cut filter proportion and removing an IR contribution from an image by using the calculated proportion of IR radiation.
