Data processing apparatuses, data processing method, program, and camera system

A data processing method comprising:

• sorting, into multiple groups by information data of a same type, input data including information data of multiple types formed by multiple bits;
• extracting a maximum value of said information data in each of said groups sorted in the data sorting;
• and
• determining a reduction position of bits common to the information data of the same type in each group on the basis of said maximum value extracted in the maximum value extraction and reducing said common bits in accordance with the determination.

A program for causing a computer to execute data processing comprising:

• sorting, into multiple groups by information data of a same type, input data including information data of multiple types formed by multiple bits;
• extracting a maximum value of said information data in each of said groups sorted in the data sorting;
• and
• determining a reduction position of bits common to the information data of the same type in each group on the basis of said maximum value extracted in the maximum value extraction and reducing said common bits in accordance with the determination.

A camera system comprising:

• an optical system;
• an imaging device configured to image a subject image passing through said optical system and output raw data;
• and
• a data processing apparatus configured to process said raw data,
• wherein said data processing apparatus has
• a data sort block configured to sort, into multiple groups by information data of a same type, input raw data including color information data of multiple types formed by multiple bits,
• a maximum value extraction block configured to extract a maximum value of said color information data in each of said groups sorted by said data sort block, and
• a bit position decision and bit reduction block configured to determine a reduction position of bits common to the color information data of the same type in each group on the basis of said maximum value extracted by said maximum value extraction block and reduce said common bits in accordance with the determination.
