Image processing device for determining output resolution and converting scan data into image data indicating output resolution

摘要

An image processing device may calculate, by utilizing scan data obtained by a scan of a document including a natural image in accordance with a specific optical resolution, a first type of index value for classifying the document, determine an output resolution by utilizing the first type of index value, convert the scan data indicating the specific optical resolution into image data indicating the output resolution in a case where the output resolution is not identical to the specific optical resolution, and create a file including the image data indicating the output resolution.

1. An image processing device comprising:
one or more processors; and a memory that stores a computer program including instructions executed by the one or more processors, wherein the instructions cause the one or more processors, when executed by the one or more processors, to function as: a character configuration analysis unit configured to calculate, by utilizing scan data obtained by a scan of a document including a natural image in accordance with a specific optical resolution, a character configuration index value indicating a configuration of a character included in the document; a judging unit configured to judge, by utilizing the character configuration index value, whether a document fineness index value indicating a fineness of the document should be calculated, the document fineness index value being a value calculated based on a number of edge pixels in the document; a document fineness analysis unit configured to
calculate, by utilizing the scan data, the document fineness index value in a case where it is judged that the document fineness index value should be calculated, andnot calculate the document fineness index value in a case where it is judged that the document fineness index value should not be calculated; an output resolution determination unit configured to
determine an output resolution by utilizing both the character configuration index value and the document fineness index value in a case where it is judged that the document fineness index value should be calculated, the output resolution being a resolution for image data obtained by utilizing the scan data, anddetermine the output resolution by utilizing the character configuration index value without utilizing the document fineness index value in a case where it is judged that the document fineness index value should not be calculated; a conversion unit configured to convert the scan data indicating the specific optical resolution into the image data indicating the output resolution in a case where the output resolution is not identical to the specific optical resolution; and a creation unit configured to create a file including the image data indicating the output resolution.
