Image processing apparatus capable of preventing page missing, control method therefor, and storage medium

Abstract

An image processing which is capable of preventing page missing even when there is an image having no foreground image. In a case where a foreground image is extracted from an obtained image, the foreground image is generated as an image for one page, and in a case where no foreground image is extracted from the obtained image, an image indicating that no foreground image is extracted is generated as an image for one page.

1 - 12 . (canceled) 
     
     
         13 . An image processing apparatus comprising:
 a reading unit configured to read a document;   an extracting unit configured to extract at least one object included in an image of the document read by the reading unit; and   a generating unit configured to generate a page image which includes the at least one object extracted by the extracting unit and does not include a remaining part which is not extracted by the extracting unit,   wherein the generating unit further generates, even if there is no object which can be extracted by the extracting unit, a page image.   
     
     
         14 . The image processing apparatus according to  claim 13 ,
 wherein the reading unit reads a plurality of documents,   wherein the extracting unit extracts at least one object included in each of images of the plurality of documents,   wherein the generating unit generates a plurality page images, each of the plurality of page images including the at least one object extracted by the extracting unit and does not include a remaining part which is not extracted by the extracting unit, and   wherein the generating unit further generates a page image for an image which includes no object which can be extracted by the extracting unit.   
     
     
         15 . The image processing apparatus according to  claim 14 , further comprising a file generating unit configured to generate a file including the plurality of page images generated by the generating unit. 
     
     
         16 . The image processing apparatus according to  claim 13 , further comprising a setting unit configured to set whether to include the remaining part in the page image to be generated by the generating unit. 
     
     
         17 . The image processing apparatus according to  claim 13 , wherein the generating unit further generates, even if there is no object which can be extracted by the extracting unit, a blank image. 
     
     
         18 . The image processing apparatus according to  claim 13 , further comprising a transmitting unit configured to transmit the page image generated by the generating unit. 
     
     
         19 . The image processing apparatus according to  claim 13 , further comprising a printing unit configured to print the page image generated by the generating unit. 
     
     
         20 . A control method for controlling an image processing apparatus which comprises a reading unit configured to read a document, the control method comprising:
 extracting at least one object included in an image of the document read by the reading unit;   generating a page image which includes the at least one object extracted and does not include a remaining part which is not extracted; and   generating, even if there is no object which can be extracted, a page image.   
     
     
         21 . A non-transitory computer readable storage medium for storing a computer program for controlling an image processing apparatus which comprises a reading unit configured to read a document, the computer program comprising:
 a code to extract at least one object included in an image of the document read by the reading unit;   a code to generate a page image which includes the at least one object extracted and does not include a remaining part which is not extracted; and   a code to generate, even if there is no object which can be extracted, a page image.
