Image browsing system and method for zooming images and method for switching among images

An image zooming method, controlling an electronic device to display images using a mouse;

• in a first state, the mouse being used for controlling the movements of a cursor and to select functions of the electronic device;
• in a second state, the movements of the mouse controlling the electronic device to zoom in or out a current display image;
• the image zooming method comprising:
• the electronic device receiving the detecting signal transmitted by the mouse, the detecting signal being generated according to an operation performed by a user on the mouse, the detecting signal being different when the operation is different;
• determining whether the current state is the second state;
• if it is determined that the current state is the second state, determining whether the detecting signal is a first zooming signal;
• and
• if it is determined that the detecting signal is the first zooming signal, the electronic device zooming in the current display image.

An image switching method, controlling an electronic device to display images using a mouse;

• in a first state, the mouse being used for controlling the movements of a cursor and to select functions which the electronic device offers by display;
• in a second state, the movements of the mouse controlling the electronic device to switch among the images;
• the image switching method comprising:
• the electronic device receiving the detecting signal transmitted by the mouse, the detecting signal being generated according to an operation performed by a user on the mouse, the detecting signal being different when the operation is different;
• determining whether the current state is the second state;
• if it is determined that the current state is the second state, determining whether the detecting signal is a first switching signal;
• and
• if it is determined that the detecting signal is the first switching signal, the electronic device displaying an image with next lowest numerical file number.
