Image processing apparatus and computer program product for overlaying and displaying images in a stack

A computer-readable medium storing computer readable instructions thereon for overlaying images in a stack, the computer-readable instructions when executed by a computer cause the computer to perform a method comprising:

• generating a finished image showing a result of a process performed on a target image according to various function setting items;
• generating, when the target image extends to a plurality of pages, a transparent finished image using an adjustable transparent parameter value from a continuous range of adjustable transparent parameter values to adjust a transparency of a non-image portion of each of the pages of the finished image to a predetermined transparency;
• forming the transparent finished image in a stack;
• and
• displaying a stacked transparent finished image such that an image portion of the transparent finished image is seen through the non-image portion,
• wherein the process performed on the target image includes calculating characteristic values of the target image, the characteristic values including a document state characteristic value, an image characteristic value, and a layout characteristic value.

A method for overlaying images in a stack, the method comprising:

• generating, at finished-image generating unit, a finished image showing a result of a process performed on a target image according to various function setting items;
• generating, at a transparent-finished-image generating unit, when the target image extends to a plurality of pages, a transparent finished image using an adjustable transparent parameter value from a continuous range of adjustable transparent parameter values to adjust a transparency of a non-image portion of each of the pages of the finished image to a predetermined transparency;
• forming, at a transparent-finished-image displaying unit, the transparent finished image in a stack;
• and
• displaying, at a transparent-finished-image displaying unit, a stacked transparent finished image such that an image portion of the transparent finished image is seen through the non-image portion,
• wherein the process performed on the target image includes calculating characteristic values of the target image, the characteristic values including a document state characteristic value, an image characteristic value, and a layout characteristic value.
