Abstract:
1. An image processing system comprising: an image capturing apparatus for capturing an image of a subject, the image capturing apparatus including: an image pick-up unit which captures the image; a resolution conversion unit which performs resolution conversion processing on the image by interpolation processing in electronic zoom processing; an edge enhancement processing unit which performs edge enhancement processing on the image; a storing unit which stores resolution conversion information in association with the image, the resolution conversion information indicating zoom magnification of the electronic zoom processing, and edge enhancement processing information, which indicates a procedure of the edge enhancement processing performed by said edge enhancement processing unit, in association with the image; and an output unit which outputs the resolution conversion information and the edge enhancement processing information in association with the image; and an image processing apparatus for performing image processing on the image including: a receiving unit which receives the image and the resolution conversion information and the edge enhancement processing information; an edge enhancement processing unit which performs edge enhancement processing on the image; and a control unit which controls a level of edge enhancement processing by said edge enhancement processing unit based on the resolution conversion information and the edge enhancement processing information; wherein said control unit of the image processing apparatus further judges whether the edge enhancement processing performed by the image capturing apparatus has been performed according to a level of the resolution conversion processing performed by the image capturing apparatus based on the resolution conversion information and the edge enhancement processing information, and decides a level of edge enhancement processing performed by the image processing apparatus based on the judgment such that if the resolution conversion information indicates that the resolution conversion processing procedure performed on the image was interpolation processing in electronic zoom processing, and the edge enhancement processing information indicates that the edge enhancement processing performed by the image capturing apparatus has been performed at a predetermined level irrespective of the resolution conversion processing performed by the image capturing apparatus, then said control units control the level of edge enhancement performed by the image processing apparatus based on a zoom magnification of the image capturing apparatus including in said resolution conversion information; and if the edge enhancement processing information indicates that edge processing performed by the image apparatus was performed according to the resolution conversion processing performed by the image apparatus, then said control unit control the level of edge enhancement performed by the image processing apparatus to a predetermined level.
