An image reading apparatus includes a light guide including a light guide portion configured to guide light emitted from a plurality of light sources, a deflection portion configured to deflect and emit light guided by the light guide portion, and a projection portion. The light guide portion includes a first surface and a second surface configured to internally reflect the light from the light sources. At least one of the first surface and the second surface includes a concave portion positioned to cover the projection portion in the arrangement direction. In a plane passing through the concave portion and parallel to the arrangement direction, a distance between the first surface and the second surface in a portion where the concave portion is formed is smaller than a distance between the first surface and the second surface in a portion where the concave portion is not formed.

A camera array, an imaging device and/or a method for capturing image that employ a plurality of imagers fabricated on a substrate is provided. Each imager includes a plurality of pixels. The plurality of imagers include a first imager having a first imaging characteristics and a second imager having a second imaging characteristics. The images generated by the plurality of imagers are processed to obtain an enhanced image compared to images captured by the imagers. Each imager may be associated with an optical element fabricated using a wafer level optics (WLO) technology.
