1. A development processing apparatus that performs development processing on the basis of an image file that contains an undeveloped image data created by a digital camera and contains an accompanying image data that accompanies the undeveloped image data, the accompanying image data being image data that has been subjected to development, the development processing apparatus comprising: an actual development processing section that creates actually developed image data conforming to a predetermined format from the undeveloped image data; a first analysis-purpose image generating section that creates a first analysis-purpose image data having a predetermined resolution by performing development processing on the undeveloped image data; a second analysis-purpose image generating section that creates a second analysis-purpose image data having a predetermined resolution from the accompanying image data; a development condition determining section that determines development conditions that are to be used by the actual development processing section by analyzing either one of the first analysis-purpose image data and the second analysis-purpose image data; and an analysis-purpose image data selecting section that selects either one of the first analysis-purpose image data and the second analysis-purpose image data as analysis-purpose image data that is to be used in the analysis performed by the development condition determining section on the basis of precedence between the first analysis-purpose image data and the second analysis-purpose image data.
