Image sensor configured for dual mode operation

An image sensor comprising an image sensor substrate having an array of pixels formed thereon, said array of pixels comprising:

• a first pixel region comprising a contiguous first array of pixels, said first array of pixels comprising only pixels configured for peak sensitivity to wavelength(s) below 700 nm;
• and
• a second pixel region comprising a contiguous second array of pixels of at least 300 pixels, said second array of pixels comprising pixels of a first pixel type and pixels of a second pixel type, wherein
• pixels of the first pixel type are configured for peak sensitivity to wavelength(s) between 700 nm and 1000 nm;
• and
• pixels of the second pixel type are configured for peak sensitivity to wavelength(s) below 700 nm,
• wherein the first pixel region surrounds the second pixel region such that an average distance of pixels within the second pixel region from a center of the image sensor is less than an average distance of pixels within the first pixel region from the center of the image sensor.
