Abstract
There is provided a scanner that combines images read by a first sensor array and a second sensor array, in which the first sensor array and the second sensor array have read regions which are overlapped partially, and includes a combining section that combines a first read image read by the first sensor array and a second read image read by the second sensor array and a correction section that corrects an image after a combining based on a degree of displacement of a reading position of the document.
Claims11
A scanner that combines images read by a first sensor array and a second sensor array,
- wherein the first sensor array and the second sensor array have read regions which are overlapped partially, and
- the scanner comprises:
- a combining section that combines a first read image read by the first sensor array and a second read image read by the second sensor array;
- an acquisition section that acquires a degree of relative deviation between the first read image and the second read image in a main scanning direction in a region read by the first sensor array and the second sensor array in an overlapped manner;
- and
- a correction section that corrects an image after a combining based on the degree.
A non-volatile storage medium that stores a scan program, the program causing
- a computer that controls a scanner for combining images read by a first sensor array and a second sensor array and a scanner in which read regions are overlapped partially in the first sensor array and the second sensor array to function as:
- a combining section that combines a first read image read by the first sensor array and a second read image read by the second sensor array;
- an acquisition section that acquires a degree of relative deviation between the first read image and the second read image in a main scanning direction in a region read by the first sensor array and the second sensor array in an overlapped manner;
- and
- a correction section that corrects an image after a combining based on the degree.
A method of producing scan data using a scanner for combining images read by a first sensor array and a second sensor array and a scanner in which read regions are overlapped partially in the first sensor array and the second sensor array, the method comprising:
- combining a first read image read by the first sensor array and a second read image read by the second sensor array;
- acquiring a degree of relative deviation between the first read image and the second read image in a main scanning direction in a region read by the first sensor array and the second sensor array in an overlapped manner;
- and
- correcting an image after a combining based on the degree.
