| Description: Defines the type of Color Filter Array (CFA) used to encode multiple colors in a single exposure. The most common example of this is the Bayer pattern. This is optional if there is no CFA. Additional attributes, specific to each CFA type, define whether or not the CFA pattern has been removed, and if so, how (e.g. bayer_algorithm). |
