Image processing apparatus, method, and computer program product for converting image data

A method of processing an image that is executed by an image processing apparatus including a memory unit, the method comprising:

• performing read-out image processing on input image data;
• storing the image data on which the image processing has been performed in the memory unit;
• performing determination image processing on the image data that is stored in the memory unit;
• determining an attribute of the image data on which the determination image processing has been performed;
• performing output image processing on the image data in accordance with the determined attribute;
• and
• outputting the image data on which the output image processing has been performed at the output image processing, wherein the determining the attribute includes,
• inversely converting the image data stored in the memory unit into the image data that is before the image processing performed by the read-out image processing unit as the determination image processing by the output attribute determining unit,
• determining, by the output attribute determining unit, an attribute of the inversely converted image data, and
• the inversely converting includes performing a filtering process and a color conversion process.

A computer program product comprising a non-transitory computer-usable medium having computer-readable program codes embodied in the medium for processing information in an image processing apparatus including a memory unit, the program codes when executed causing a computer to execute:

• performing read-out image processing on input image data;
• storing the image data on which the image processing has been performed in the memory unit;
• performing determination image processing on the image data that is stored in the memory unit;
• determining an attribute of the image data on which the determination image processing has been performed;
• performing output image processing on the image data in accordance with the determined attribute;
• and
• outputting the image data on which the output image processing has been performed at the output image processing, wherein the determining the attribute includes,
• inversely converting the image data stored in the memory unit into the image data that is before the image processing performed by the read-out image processing unit as the determination image processing,
• determining, by the output attribute determining unit, an attribute of the inversely converted image data, and
• the inversely converting includes performing a filtering process and a color conversion process.
