Image processing apparatus, image processing method, and computer program product

摘要

In a computer system of the invention, a menu button BT 2 'Retouching Pre-Process' clicked to activate a retouching pre-process and a menu button BT 3 'Retouching Post-Process' clicked to activate a retouching post-process are vertically downward aligned in a processing menu window MN corresponding to an order of operation procedure. The retouching pre-process includes 16-bit color support image processing options, for example, 'brightness adjustment' and 'contrast adjustment'. The retouching post-process includes 8-bit color support image processing options, for example, 'unsharp mask' and 'light irradiation'. When the operator clicks the menu button BT 2 'Retouching Pre-process' to execute any image processing option included in the retouching pre-process after execution of any image processing option included in the retouching post-process with regard to input image data, the computer system opens a message box to notify the operator of prohibition of a return to the retouching pre-process. The computer system thus effectively prevents execution of any image processing option included in the retouching pre-process after execution of any image processing option included in the retouching post-process. This arrangement desirably prevents potential deterioration of the picture quality in a retouching process that includes both the 16-bit color support image processing and the 8-bit color support image processing.
