Abstract

An image apparatus (210) for capturing an image (214) of a scene (12) includes an image sensor assembly (240) and a filter array (242). The image sensor assembly (240) includes a photosites (446). The filter array (242) filters light that is directed at the image sensor assembly (240). The filter array (242) includes a plurality of blue filters (B), a plurality of green filters (G), and a plurality of red filters (R) that are arranged in an array. The number of red filters (R) is greater than the number of blue filters (B), and the number of red filters (R) is greater than the number of green filters (G). Additionally, the image apparatus (210) can include a waterproof housing (228) that protects the image sensor assembly (240) and the filter array (242).
