[0034]

[0035] figure 1 is a diagram showing the overall configuration of the image processing system 100 according to the present embodiment. The image processing system 100 includes a Multi Function Peripheral (MFP) 110 and server devices 120 and 130 that provide cloud services on the Internet. MFP 110 is communicably connected to server devices 120 and 130 via the Internet.

[0036] The MFP 110 is an example of an information processing device having a scanning function. The MFP 110 is a multifunctional peripheral that has multiple functions such as a printing function and a box saving function in addition to a scanning function. The server devices 120 and 130 are both examples of information processing devices that provide cloud services. The server device 120 of the present embodiment provides cloud services to perform predetermined image analysis processing on scanned image data received from the MFP 110, transmits requests from the MFP 110 to the server device 130...

[0099] In the first embodiment, based on the size of the document overlap area, it is determined whether there is a possibility that a key or a value is hidden. Next, an aspect in which the determination accuracy of the occlusion determination process is improved by performing determination based on the positional relationship between a character string of a key or a character string of a value and an overlapping area is set forth as a second embodiment.

[0100] Figure 23B is a flowchart showing details of occlusion determination processing according to the present embodiment. The shading determination processing according to the first embodiment is omitted or simplified ( Figure 23A The flow chart in ) is explained in common, and in the following, mainly different points are explained.

[0107] For many business forms, such as receipts and estimates, the format is standardized and the location of the key or value is determined. Therefore, an aspect has been set forth as a third embodiment in which, for a document whose format is known in advance, by using positional information on a character string corresponding to a keyword or a value, whether or not a keyword or a value is hidden can be more accurately determined .

[0108] Figure 24 is a flowchart showing details of occlusion determination processing according to the present embodiment. Explanations of common contents to those of the occlusion determination processing according to the first embodiment and the second embodiment are omitted or simplified, and hereinafter, different points are mainly explained.

Abstract

The invention provides an image processing apparatus, an image processing method, and a storage medium. At the time of registering an image in units of documents, which is obtained by performing multi-cropping processing for a scanned image, and value information extracted from each image in a database in association with each other, there is a case where it is not possible to extract the value information successfully because of an overlap between documents during a scan. In a case where this fact is noticed after registration, it becomes necessary for a user to perform the entire work from the beginning. In a case where there is a possibility that the value information is hidden by an overlap between documents during a scan or the like, a display is produced for prompting a user to scanthe document again.

Description

technical field [0001] The present disclosure relates to multiple cropping of scanned images. Background technique [0002] Currently, there is a fee settlement system in which an image in units of receipts (one-to-one correspondence with receipts) is acquired by performing multiple cropping processing on a cloud service on an image obtained by scanning a plurality of receipts as a whole. image), and specific character strings such as date (Date) and amount (Amount) are extracted therefrom, and registered in the database in association with each image. A specific character string registered in association with an image is also called "value information", and a user can check the registered value information by accessing the database. Then, when the value information is wrongly registered, it is also possible to correct the value to a correct value by referring to an image associated with the value information. [0003] When scanning a plurality of originals at the same tim...
