Apparatus and method for reducing current consumption in portable terminal with flexible display
An apparatus and method for reducing current consumption in a portable terminal with a flexible display are provided. The apparatus includes at least one camera mounted on a first region of the portable terminal, a flexible display including a first area defined in the first region including the mounted camera and a second area defined in a second region not including the mounted camera, when the portable terminal is bent, and a controller for controlling the flexible display. If the image photographed through the camera includes a face image when the portable terminal is bent, information data is displayed on the first area and null data is displayed on the second area. If the image photographed through the camera does not include a face image when the portable terminal is bent, the null data is displayed on the first area and the information data is displayed on the second area.
1. An apparatus for reducing current consumption in a portable terminal including a flexible display, the apparatus comprising:
at least one camera mounted on a first region of the portable terminal;
a first area of the flexible display, when the portable terminal is bent, defined in the first region including the mounted camera;
a second area of the flexible display, when the portable terminal is bent, defined in a second region not including the mounted camera; and
a controller for controlling the flexible display to display information data on the first area and null data on an entirety of the second area, if an image photographed through the camera comprises a face image when the portable terminal is bent, and for controlling the flexible display to display the null data on an entirety of the first area and the information data on the second area, if the image photographed through the camera does not comprise a face image when the portable terminal is bent.
2. The apparatus of claim 1 , further comprising:
a memory for storing a first area value and a second area value of the flexible display;
a bending recognition sensor for detecting a bent state of the portable terminal; and
a face recognition sensor for detecting a face image photographed through the camera when the portable terminal is bent.
3. The apparatus of claim 1 , wherein the controller controls the camera to photograph the image if a bending recognition sensor detects a bent state of the portable terminal.
4. The apparatus of claim 1 , wherein the controller controls the flexible display to display the information data on the first area and the null data on the second area, if the face recognition sensor detects the image photographed through the camera as a face image.
5. The apparatus of claim 1 , wherein the controller controls the flexible display to display the null data on the first area and the information data on the second area, if at least one of the image photographed through the camera does not comprise the face image and brightness of the photographed image comprises less than a preset reference value.
6. The apparatus of claim 1 , wherein the null data comprises black data.
7. A method for reducing current consumption in a portable terminal with a flexible display, the method comprising:
photographing an image through a camera when a bent state of the portable terminal is detected;
if the photographed image comprises a face image, displaying information data on a first area of the flexible display located in a first region including the mounted camera and displaying null data on an entirety of a second area of the flexible display located in a second region not including the mounted camera; and
if the photographed image does not comprise a face image, displaying the null data on an entirety of the first area of the flexible display and displaying the information data on the second area of the flexible display.
8. The method of claim 7 , wherein the bent state of the portable terminal is detected by a bending recognition sensor.
9. The method of claim 7 , wherein the face image is detected by a face recognition sensor.
10. The method of claim 7 , further comprising:
if the photographed image does not comprise the face image, extracting a brightness value of the photographed image; and
if the brightness value of the photographed image comprises less than a preset reference value displaying the null data on the first area and displaying the information data on the second area.
11. The method of claim 7 , wherein the null data comprises black data.
