Abstract
An image processing apparatus having a reading device to read an image from a sheet includes one or more controllers to perform operations. One image is read from one sheet by using the reading device. Edge detection processing is executed on the one image. At least one pair of edges is determined from among a plurality of edges based on information of the plurality of edges detected in the edge detection processing and size information of the one sheet.
Claims17
An image processing apparatus having a reading device to read an image from a sheet, the image processing apparatus comprising:
- one or more controllers configured to perform operations including:
- reading one image from one sheet by using the reading device,
- executing edge detection processing on the one image, and
- determining at least one pair of edges from among a plurality of edges based on information of the plurality of edges detected in the edge detection processing and size information of the one sheet.
An image processing apparatus having a reading device to read an image from a sheet, the image processing apparatus comprising:
- one or more controllers configured to perform operations including:
- reading a plurality of images from a plurality of sheets by using the reading device,
- executing edge detection processing on the read plurality of images,
- acquiring size information representing the plurality of sheets from a plurality of results obtained by the edge detection processing, and
- determining at least one pair of edges based on a plurality of pieces of edge information corresponding to one image from among the plurality of images and the size information representing the plurality of sheets.
A method for an image processing apparatus having a reading device to read an image from a sheet, the method comprising:
- reading one image from one sheet by using the reading device;
- executing edge detection processing on the one image;
- and
- determining at least one pair of edges from among a plurality of edges based on information of the plurality of edges detected in the edge detection processing and size information of the one sheet.
A non-transitory computer-readable storage medium storing computer-executable instructions for causing a computer to execute a method for an image processing apparatus having a reading device to read an image from a sheet, the method comprising:
- reading one image from one sheet by using the reading device;
- executing edge detection processing on the one image;
- and
- determining at least one pair of edges from among a plurality of edges based on information of the plurality of edges detected in the edge detection processing and size information of the one sheet.
