Abstract

A mobile terminal and recording controlling method thereof are disclosed. The present invention includes performing a call with a counterpart terminal, buffering a call content of the performed call by a predetermined time unit, receiving an input of a recording command signal for the performed call, and if receiving the input of the recording command signal, recording the call content from an input point of the recording command signal by including the call content from a random point in a time interval corresponding to the call content buffered up to the input point of the recording command signal.

Claims

1. A mobile terminal comprising:

a camera configured to receive a preview image;

a memory configured to buffer the preview image by a predetermined time unit;

a display including an upper main display portion and a lower display portion and configured to display the preview image in the main display portion; and

a controller configured to;

receive a touch input of a capture icon on the display,

buffer the preview image currently being displayed in the main display portion,

display a plurality of thumbnail images in the lower display portion below the main display portion when the capture icon is selected, wherein the plurality of thumbnail images include at least a thumbnail image of the preview image being displayed when the capture icon was touched and thumbnail images of the preview image before the capture icon was touched,

receive a touch selection of one of the thumbnails displayed in the lower display portion,

display the touch selected thumbnail image in the main display portion, and

maintain the display of the plurality of thumbnail images including the touch selected thumbnail image in the lower display portion.

2. The mobile terminal of claim 1, wherein the camera photographs a first still picture and a second still picture sequentially when the capture icon is selected,

wherein the controller controls the memory to buffer the preview image ranging between a photographing point of the first still picture and a photographing point of the second still picture, and

wherein the selected capture icon corresponds to a photographing command signal for the second still picture.

3. The mobile terminal of claim 1, wherein the controller receives a setting of a predetermined time interval for buffering the received preview image.

4. The mobile terminal of claim 3, wherein the controller receives a selection of a random point in the time interval.

5. The mobile terminal of claim 4, wherein when the capture icon is selected, the controller controls the memory to interrupt the buffering of the preview image and to delete the preview image before the random point in the preview image buffered up to the input point of the selected capture icon.

6. The mobile terminal of claim 4, wherein when a recording end command signal is received, a recorded image includes the preview image corresponding to a period between the random point and an input point of the recording end command signal.

7. The mobile terminal of claim 6, wherein the display displays an indicator indicating a recording extent of the recorded image, and

wherein the indicator represents the recorded image corresponding between the random point and the input point of the recording command signal as a recording completed part.

8. A method of controlling a mobile terminal, the method comprising:

receiving, via a camera, a preview image;

buffering, via a memory, the preview image by a predetermined time unit;

displaying, via a display including an upper main display portion and a lower display portion, the preview image in the main display portion;

receiving, via a controller, a touch input of a capture icon on the display;

buffering, via the memory, the preview image currently being displayed in the main display portion;

displaying, via the display, a plurality of thumbnail images in the lower display portion below the main display portion when the capture icon is selected, wherein the plurality of thumbnail images include at least a thumbnail image of the preview image being displayed when the capture icon was touched and thumbnail images of the preview image before the capture icon was touched;

receiving, via the controller, a touch selection of one of the thumbnails displayed in the lower display portion;

displaying, via the display, the touch selected thumbnail image in the main display portion; and

maintaining, via the controller, the display of the plurality of thumbnail images including the touch selected thumbnail image in the lower display portion.

9. The method of claim 8, wherein the camera photographs a first still picture and a second still picture sequentially when the capture icon is selected,

wherein the buffering step buffers the preview image ranging between a photographing point of the first still picture and a photographing point of the second still picture, and

wherein the selected capture icon corresponds to a photographing command signal for the second still picture.

10. The method of claim 8, further comprising:

receiving, via the controller, a setting of a predetermined time interval for buffering the received preview image.

11. The method of claim 10, wherein the receiving the setting receives a selection of a random point in the time interval.

12. The method of claim 11, wherein when the capture icon is selected, the method further comprises interrupting the buffering of the preview image and deleting the preview image before the random point in the preview image buffered up to the input point of the selected capture icon.

13. The method of claim 11, wherein when a recording end command signal is received, a recorded image includes the preview image corresponding to a period between the random point and an input point of the recording end command signal.

14. The method of claim 13, wherein the displaying step further displays an indicator indicating a recording extent of the recorded image, and

wherein the indicator represents the recorded image corresponding between the random point and the input point of the recording command signal as a recording completed part.
