Apparatus for and method of controlling digital image processing apparatus
First Claim
1. An apparatus for controlling a digital image processing device that includes an image input unit for receiving an image for photographing and a display unit for displaying the image, the apparatus comprising:
- a motion sensing unit in communication with the image input unit that determines whether the digital processing unit has moved or is moving by assessing whether the difference between an evaluation index of a current image frame and an evaluation index of a previous image frame is greater than a preset reference value and generates a motion sensing signal according to the determination; and
a control unit in communication with the motion sensing unit for receiving the motion sensing signal, the control unit operating the digital image processing device in a power saving mode,wherein the display unit operates in a reduced power consumption mode when, according to the motion sensing signal, the control unit determines that the digital image processing device has moved or is moving.

Abstract
An apparatus for and method of controlling a digital image processing device in order to reduce power consumption by automatically recognizing a state in which power of a display device can be turned off or the display device can operate in a power saving mode, and in that case, turning off the display device or operating the display device in the power saving mode. The apparatus for controlling a digital image processing device includes: a motion sensing unit sensing a motion of the digital image processing device; and a control unit operating the digital image processing device in a power saving mode when it is determined that the digital image processing device moves.

11. A method for controlling a digital image processing device including an image input unit for receiving an image for photographing and a display unit for displaying the image, the method comprising:
-
sensing a motion of the digital image processing device by extracting evaluation indexes of a current image frame and a previous image frame and assessing whether the difference between evaluation indexes of the current and previous image frames is greater than a preset reference value; generating a motion sensing signal if the difference is greater than the preset reference value; and operating the digital image processing device in a power saving mode wherein the display unit of the digital image processing device operates in a reduced power consumption mode when, according to the motion sensing signal, it is determined that the digital image processing device moved or is moving. - View Dependent Claims (12, 13, 14, 15)
