IMAGE INPUTTING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2010/053029

Kind Code:

A1

Abstract:

Provided is an image inputting apparatus wherein luminance signals having a high S/N ratio can be generated even during nighttime with a small quantity of photons. An imaging element (3) images image components (Ye, R, IR, W). A color signal generating section (42) generates color signals (dR, dG, dB) from the image components (Ye, R, IR, W). A color space conversion section (43) converts the color signals (dR, dG, dB) into a color space that includes luminance signals and color difference signals. The color space conversion section (43) calculates a luminance signal (Yadd) obtained by adding the image components (Ye, R, IR, W), as the luminance signal of the color space to be converted.
