Abstract

A document processing device, a method of processing an image thereof, and a computer program product are disclosed. A set of display area information is preset on the document processing device. When the document processing device receives an input image, a set of reference information corresponding to the input image is obtained. The document processing device adjusts the input image according to the set of display area information and the set of reference information to generate an improved preview image. Because the user does not need to consider the direction in which the document is put into the document processing device, the document processing device directly and automatically generates the preview image that is convenient for the user to view based on the input image, thereby achieving the purpose of improving work efficiency, the convenience in use, and the user experience.

Claims18

Dependent claims

A document processing device, comprising:

a display module, having a document preview area that is defined by two first long sides and two first short sides;
a storage module, for storing a set of display area information related to the document preview area, wherein the set of display area information comprises a set of first long side information related to the two first long sides of the document preview area, wherein the set of first long side information comprises a length information, a position information and a direction information of the two first long sides;
an image input module, configured to receive an input image that is defined by two second long sides and two second short sides;
and
a processing module, connected with the image input module, the display module, and the storage module;
wherein the processing module is configured to receive the input image through the image input module and a set of reference information comprising a set of second long side information related to the two second long sides of the input image, wherein the set of second long side information comprises a length information, a position information and a direction information of the two second long sides;
wherein the processing module adjusts the input image according to the set of display area information and the set of reference information to generate an improved preview image that corresponds to the document preview area;
wherein, when the processing module determines the position information or direction information in the set of second long side information fails to correspond to the position information or direction information in the set of first long side information, the processing module carries out an image rotation processing for the input image to generate the improved preview image and the document preview area only displays the one improved preview image.

5 more elements

A method of processing an image of a document processing device, executed on the document processing device with a document preview area, the method comprising:

presetting a set of display area information related to the document preview area, wherein the set of display area information comprises a set of first long side information related to two first long sides of the document preview area that is defined by the two first long sides and two first short sides, wherein the set of first long side information comprises a length information, a position information and a direction information of the two first long sides;
obtaining a set of reference information of an input image comprising a set of second long side information related to two second long sides of the input image when receiving the input image that is defined by the two second long sides and two second short sides, wherein the set of second long side information comprises a length information, a position information and a direction information of the two second long sides;
and
adjusting the input image according to the set of display area information and the set of reference information to generate an improved preview image that corresponds to the document preview area,
wherein, when the position information or direction information in the set of second long side information fails to correspond to the position information or direction information in the set of first long side information, an image rotation processing is executed for the input image to generate the improved preview image and only the one improved preview image is displayed in the document preview area.

2 more elements

A computer program product including a non-transitory storage medium having program instructions stored thereon that, when executed on a document processing device with a document preview area, cause the document processing device to execute a method of processing an image of the document processing device, the method comprising steps of:

presetting a set of display area information related to the document preview area, wherein the set of display area information comprises a set of first long side information related to two first long sides of the document preview area that is defined by the two first long sides and two first short sides, wherein the set of first long side information comprises a length information, a position information and a direction information of the two first long sides;
obtaining a set of reference information of an input image comprising a set of second long side information related to two second long sides of the input image when receiving the input image that is defined by the two second long sides and two second short sides, wherein the set of second long side information comprises a length information, a position information and a direction information of the two second long sides;
and
adjusting the input image according to the set of display area information and the set of reference information to generate an improved preview image that corresponds to the document preview area,
wherein, when the position information or direction information in the set of second long side information fails to correspond to the position information or direction information in the set of first long side information, an image rotation processing is executed for the input image to generate the improved preview image and only the one improved preview image is displayed in the document preview area.
