Abstract
A user terminal device and a method for controlling the same are provided. The user terminal device includes a sensor configured to sense a user touch operation for a binarized text image, a controller configured to generate an indicator pointing out a point where the user touch operation is sensed, when the user touch operation is sensed by the sensor, and a display unit configured to display the binarized text image and the generated indicator.
Claims15
A user terminal device comprising:
- an image receiver configured to acquire a text image including a text which is photographed by a camera;
- a sensor configured to sense a user touch operation for a binarized text image of the acquired text image;
- a processor configured to generate an indicator pointing out a point where the user touch operation is sensed when the user touch operation is sensed by the sensor;
- and
- a display configured to display the binarized text image and the generated indicator at the point where the user touch operation is sensed,
- wherein the processor is further configured to:
- detect a user's hand area pointing out the text in the text image, and
- obtain the binarized text image by performing binarization on a remaining area other than the user's hand area and synthesizing the binarized remaining area with the user's hand area.

- and
- a display configured to display the binarized text image and the generated indicator at the point where the user touch operation is sensed,
- wherein the processor is further configured to:
- detect a picture area, a graph area, and a figure area other than a text area,
- obtain the binarized text image in which only the text area is binarized without performing binarization on the picture area, the graph area, and the figure area while the text area is binarized, and
- control the display to control a size of an area in which the user touch operation is sensed and display the controlled area when the user touch operation is sensed in one of the picture area, the graph area, and the figure area.
