    • An object of the invention is to prevent degradation of an image as much as possible when data of the number of original pixels of an image sensing element is converted into data of a smaller number of pixels. In order to achieve this object, an image data reduction apparatus which converts first image data in which elements of a plurality of colors are arrayed within a plane into second image data having a smaller number of elements than the first image data by reducing the number of elements in the longitudinal direction, the lateral direction, or both the longitudinal and lateral directions within the plane includes an image processing circuit which performs one or both of a process of assigning one element of the first image data to one element of the second image data, and a process of processing a plurality of elements of the first image data and assigning the elements to one element of the second image data, so as to array the barycenters of the elements of the second data at equal intervals in a direction in which the number of elements is reduced out of the longitudinal direction, the lateral direction, or both the longitudinal and lateral directions.
