Abstract

A handwriting storing and reproducing method which takes small images including a leading edge for writing and stores the small images in a time sequential manner following a movement of a writing device. The method then reads out the stored small images and overlaps a just read out small image to a previously read out small image so as to obatain a partial image when both small images include portions which include partial handwritings coincident to one another. Thereafter, the method overlaps one partial image to another partial image-so as to obtain a larger image when both partial images include portions which include partial handwritings coincident to one another.

Claims

1. An image reproducing method for reproducing a large image from plural small images, comprising:

sequentially reading out the small images,

comparing a just read out small image with a previously read out small image so as to obtain a portion of the just read out small image which is coincident with a portion of the previously read out small image,

overlapping the just read out small image to the previously read out small image so that the portion in the just read out small image exactly overlays the portion in the previously read out small image to obtain a new image,

defining the new image as the previously read out small image, and

repeating the comparing step, the overlapping step and the defining step for each subsequent read out small image.

2. An image reproducing method for reproducing a large scene image from sequential plural small cell images, comprising:

1) defining a first cell image as an act image;

2) comparing a subsequent cell image with a matching region of the act image to identify a portion of the subsequent cell image which is coincident with a portion of the act image within the matching region;

3) modifying the act image by combining the subsequent cell image with the act image so that the portion of the subsequent cell image overlaps the portion of the cell image;

4) repeating steps 2 and 3 for each subsequent cell image which has a portion coincident with a portion of the act image within the matching region;

5) defining the act image as a scene image;

6) defining a subsequent cell image as the act image;

7) repeating steps 2, 3, and 4;

8) comparing the act image with the scene image to identify a portion of the act image which is coincident with a portion of the scene image;

9) modifying the scene image by combining the act image with the scene image so that the portion of the act image overlaps the portion of the scene image; and

10) repeating steps 6, 7, 8, and 9 for each act image which has a portion coincident with a portion of the scene image.
