Method for improving image sensitivity and color information for image from camera device in vehicle, involves reconstructing color information within visible spectral range based on infrared pass filter coating on selected sub-pixels

摘要

The method involves applying an infrared (IR) pass filter coating on selected sub-pixels such that near infrared light is passed within a predetermined wavelength portion by the selected sub-pixels. The transmission of visible light is blocked with color information by the selected sub-pixels. The color information is reconstructed within a visible spectral range for the sub-pixels for long exposure and short exposure to the color-sensitive pixels based on the applied IR-pass filter coating on the selected sub-pixels.
