Image reading device and method, reading area display device and method, and program
First Claim
1. An image reading device, comprising:
- a reading unit that, via an imaging device, performs reading of a printed material on which an image is printed on the basis of manuscript image data;
an image acquisition unit that, via a processor, acquires the manuscript image data from an outside of the image reading device;
an image analysis unit that, via the processor, analyzes the manuscript image data and detects a feature amount to be used for specifying a positional relationship between the manuscript image data and read image data of the printed material read by the reading unit;
a reading area setting unit that, via the processor, sets a reading area in which the reading unit performs reading of the printed material, on the basis of the feature amount detected by the image analysis unit, and sets at least one or more areas including the feature amount in the manuscript image data as the reading area; and
a display unit that, via a display, displays a setting position of the printed material with respect to the reading unit on the basis of a result of the setting of the reading area by the reading area setting unit,wherein the reading unit performs reading of the printed material set in the reading unit after the setting position is displayed by the display unit.

Abstract
In a preferred aspect of the present invention, manuscript image data is analyzed, and a feature amount to be used for specifying a positional relationship between the manuscript image data and read image data of a printed material read by a reading unit that performs reading of the printed material on which an image is printed on the basis of the manuscript image data, is detected. At least one or more areas including the feature amount in the manuscript image data is set as a reading area. A setting position of the printed material with respect to the reading unit is displayed on the basis of a result of the setting of the reading area. Reading of the printed material set in the reading unit is performed after the setting position is displayed by a display unit.
