Abstract:
1. An image processing device comprising: A processor configured to function as an acquiring unit that acquires, from image data, processing image data having a first resolution in a first direction and a second resolution in a second direction different from the first direction; a receiving unit that receives input of a first theoretical resolution in the first direction and a second theoretical resolution in the second direction; a tilt detecting unit that detects tilt of the image data in accordance with the processing image data and the first theoretical resolution and the second theoretical resolution; and wherein the tilt detecting unit converts a plurality of position information of the processing image data based on ratios of the first resolution and the first theoretical resolution and the second resolution and the second theoretical resolution, calculates a tilt angle of the image data from the converted position information and detects an average value, an intermediate value, and a most appropriate value for the image data from the converted position information.
