Abstract

The disclosure discloses an information processing method for an electronic device with a touch screen. The method includes: touch with a touch screen is detected; an information pickup area is set on the touch screen according to the touch; and information in the information pickup area is picked up according to an information pickup command and the picked-up information is stored. In the disclosure, existing information, such as an image or a signature, is picked up via an information processing device, such as a stylus, on a touch screen of an electronic device; and a user can autonomously control its image, signature and other information to display on the touch screen of the electronic device when needed. Therefore, great convenience is brought to users using a portable electronic device such as a tablet PC and a smart phone, and their personalized application can also be met to a great extent.
