Abstract
A method to correct an image in a dual-aperture camera. Infrared noise may be subtracted from a pixel of an RGB image by the amount proportional to the distance from the corresponding edge to minimize imaging defects in a dual aperture camera. Such defect minimization may prevent edge information from being lost. A method reduces the effect of false color along the edges by converting inconsistent color edges to more consistent monochrome edges using the YCbCr color space.
Claims9
A method comprising:
- generating a visible light image from visible light pixels comprised in an image sensor pixel array using a first aperture for visible light having a first width;
- generating an infrared image from infrared pixels comprised in the image sensor array using a second aperture for infrared light having a second width smaller than the first with of the first aperture, wherein the infrared image comprises infrared noise;
- identifying depicted edges from at least one of the visible light image or the infrared light image;
- and
- selectively subtracting the infrared noise from the visible light image based on a distance of an image pixel of the image sensor pixel array from the identified depicted edges.

The method of claim 8, comprising:
- identifying depicted edges in the infrared image,
- wherein said suppressing blue chrominance components Cb and red chrominance components Cr of the YCbCr color space image is based upon both the identified depicted edges in the Y luminance components of the YCbCr color space image and the identified depicted edges of the infrared image.
