JEITA  CP-3451 - 41 - 4 = Three-chip color area sensor 5 = Color sequential area sensor 7 =      Trilinear sensor 8 = Color sequential linear sensor Other = reserved FileSource Indicates the image source. If a DSC recorded the image, this tag value of this tag always be set to 3, indicating that the image was recorded on a DSC.   Tag =    41728 (A300.H) Type =    UNDEFINED Count =    1 Default =    3 3 =      DSC Other = reserved SceneType Indicates the type of scene. If a DSC recorded the image, this tag value shall always be set to 1, indicating that the image was directly photographed. Tag = 41729 (A301.H) Type = UNDEFINED Count = 1 Default = 1 1 = A directly photographed image Other = reserved CFAPattern Indicates the color filter array (CFA) geometric pattern of the image sensor when a one-chip color area sensor is used. It does not apply to all sensing methods.   Tag = 41730 (A302.H) Type = UNDEFINED Count = ANY Default = none Figure  15  shows  how  a  CFA  pattern  is  recorded  for  a  one-chip  color  area  sensor  when  the  color  filter  array  is repeated in m x n (vertical x lateral) pixel units.
