Abstract:
1. An image coding apparatus for coding RAW data of an image of a Bayer array, comprising: a separating unit configured to separate the RAW data respectively into separate planes of data of a plurality of color components constituting the Bayer array; a coding parameter generating unit configured to determine a coding method for coding each plane separated by the separating unit from a plurality of coding methods and generate a coding parameter on the basis of the determined coding method; and a coding unit configured to code each of the planes on the basis of the generated coding parameter, wherein in a case where a coding-target plane is a plane to be coded later among a plurality of planes of a same color, the coding parameter generating unit determines the coding method including an inter-plane prediction from among the plurality of coding methods, and generates the coding parameter for coding the plane to be coded later on the basis of a result of the coding of a plane to be coded earlier among the plurality of planes of the same color.
