An image input device, comprising:
- a display and image sensing unit for displaying and sensing an image, said display and image sensing unit including:
- a transparent flat plate,
- a display unit for displaying an image on said flat plate, and
- an image sensing unit for sensing an image in a range of a contact surface of a document placed on said flat plate, the contact surface being in contact with said flat plate, said display unit displaying the image in the range;
- a contact sensing unit for sensing a contact of said document with said flat plate when a message is being displayed by said display unit;
- and
- a display control unit for controlling to display an image in an even and specific color when the contact of said document has been sensed by said contact sensing unit.
4 more elements
An image input method, comprising:
- a step of sensing a contact of a document with a transparent flat plate provided for a display and image sensing unit for displaying and sensing an image, wherein the step of sensing contact of a document occurs while a message is being displayed by the display and image sensing unit;
- a step of displaying an image in an even and specific color when the contact of said document has been sensed;
- and
- a step of inputting an image on a contact surface of said document that is in contact with said flat plate by sensing the image on said contact surface when the image in said specific color is displayed.
