Split sub-pixel imaging chip with ir-pass filter coating applied on selected sub-pixels

Method for enhancing image sensitivity and color information for an image captured by a camera device using a split sub-pixel imaging chip including a plurality of color-sensitive pixels each including a long-exposure sub-pixel and a short-exposure sub-pixel, comprising:

• applying an IR-pass filter coating on selected sub-pixels, the IR-pass filter coating allowing near infrared light within a predetermined portion of wavelengths to be transmitted through the selected sub-pixels while blocking transmission of visible light comprising color information through the selected sub-pixels;
• and
• reconstructing color information within a visible spectrum range for the long-exposure and short-exposure sub-pixels for the plurality of color-sensitive pixels based on the applied IR-pass filter coating on the selected sub-pixels.

Apparatus for capturing an image, comprising:

• a split sub-pixel imaging chip receiving light transmitted through the aspheric lens element and including a plurality of green, blue and red pixels each including a long-exposure sub-pixel and a short-exposure sub-pixel, the split sub-pixel imaging chip includes an IR-pass filter coating applied on selected ones of the long-exposure and short-exposure sub-pixels for selected ones of the green pixels.
