Electronic apparatus, processing method and storage medium

A processing method of an electronic apparatus, the method comprising:

• storing first stroke data corresponding to a first handwritten stroke input on a display, wherein the first stroke data is stored in association with a first orientation of a screen displayed on the display at the time when the first handwritten stroke was input;
• detecting a second orientation of the electronic apparatus;
• controlling a third orientation of a screen displayed on the display by using the second orientation and displaying the first handwritten stroke according to the third orientation;
• receiving second stroke data corresponding to a second handwritten stroke input on the display;
• storing the second stroke data in association with the third orientation at the time when the second handwritten stroke was input.

A computer-readable, non-transitory storage medium having stored thereon a computer program which is executable by a computer comprising a memory configured to store first stroke data corresponding to a first handwritten stroke input on a display, the first stroke data being stored in association with a first orientation of a screen displayed on the display at the time when the first handwritten stroke was input, the computer program controlling the computer to function as:

• a detector configured to detect a second orientation of the electronic apparatus;
• a display controller configured to control a third orientation of a screen displayed on the display by using the second orientation and to display the first handwritten stroke according to the third orientation;
• an input controller configured to receive second stroke data corresponding to a second handwritten stroke input on the display;
• and
• a storage controller configured to store the second stroke data in association with the third orientation at the time when the second handwritten stroke was input.
