## Abstract

According to one embodiment, an electronic device includes a display controller, and a processor. The display controller displays a locus corresponding to a stroke. The processor performs one of processing of deleting a part of a first locus or processing of deleting all of the first locus, based on a vertical width and a horizontal width which correspond to the first locus.

## Claims

### Claim 1

An electronic device comprising:
a display controller configured to display a locus corresponding to a stroke; and
a processor configured to perform one of processing of deleting a part of a first locus or processing of deleting all of the first locus, based on a vertical width and a horizontal width which correspond to the first locus,
wherein the processor is configured to perform the processing of deleting all of the first locus if a ratio of the vertical width to the horizontal width is less than a first threshold or the horizontal width is less than a second threshold.

### Claim 2

(canceled)

### Claim 3 (depends on 1)

The device of claim 1, wherein the processor is configured to delete a portion that is input by handwriting after a first point if the first point on the first locus is selected and the ratio is less than the first threshold.

### Claim 4

(canceled)

### Claim 5 (depends on 1)

The device of claim 1, wherein the processor is configured to perform the processing of deleting at least the part when the horizontal width is greater than the second threshold and the vertical width is not greater than a third threshold.

### Claim 6

A handwritten document processing method comprising:
displaying a locus corresponding to a stroke; and
performing one of processing of deleting a part of a first locus or processing of deleting all of the first locus, based on a vertical width and a horizontal width which correspond to the first locus,
wherein the processor is configured to perform the processing of deleting all of the first locus if a ratio of the vertical width to the horizontal width is less than a first threshold or the horizontal width is less than a second threshold.

### Claim 7

A computer-readable, non-transitory storage medium configured to store a computer program which is executable by a computer, the computer program controlling the computer to execute functions of:
displaying a locus corresponding to a stroke; and
performing one of processing of deleting a part of a first locus or processing of deleting all of the first locus based on a vertical width and a horizontal width, which correspond to the first locus,
wherein the processor is configured to perform the processing of deleting all of the first locus if a ratio of the vertical width to the horizontal width is less than a first threshold or the horizontal width is less than a second threshold.

### Claim 8 (depends on 6)

The method of claim 6, wherein the performing comprises deleting a portion that is input by handwriting after a first point if the first point on the first locus is selected and the ratio is less than the first threshold.

### Claim 9 (depends on 6)

The method of claim 6, wherein the processing of deleting at least the part is performing when the horizontal width is greater than the second threshold and the vertical width is not greater than a third threshold.

### Claim 10 (depends on 7)

The medium of claim 7, wherein the performing comprises deleting a portion that is input by handwriting after a first point if the first point on the first locus is selected and the ratio is less than the first threshold.

### Claim 11 (depends on 7)

The medium of claim 7, wherein the processing of deleting at least the part is performing when the horizontal width is greater than the second threshold and the vertical width is not greater than a third threshold.
