Title:
VIDEO CAMERA IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2018023077
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus and signal processing for improving noise reduction and color reproducibility of a video signal at low illuminance imaging with an electronic camera.SOLUTION: In an electronic camera system that obtains video signals with a plurality of imaging elements by separating a near-infrared video signal and a visible light video signal with a plurality of optical wavelength separation prisms and optical wavelength separation films, image processing is performed with little noise only for luminance signals without changing a color signal ratio of visible light by adding a luminance signal of near infrared light to a luminance signal of visible light.SELECTED DRAWING: Figure 1
