IMAGE PROCESSING APPARATUS AND METHOD FOR CONTROLLING POWER THEREOF

摘要

An image processing apparatus according to an embodiment of the present invention comprises: a signal receiving unit for receiving an image signal; a first signal processing unit for processing the image signal, received in the signal receiving unit, according to a predetermined image processing process to be displayed as an image on a display unit; a second signal processing unit for performing a plurality of predetermined additional processes different from the image processing process; a power supply unit for supplying power to the first signal processing unit and the second signal processing unit in a normal mode of the image processing apparatus; and a controller which cuts off the power supply of the power supply unit for the first signal processing unit in a stand-by mode of the image processing apparatus, controls the power supply for the second signal processing unit so that the second signal processing unit can perform at least first additional process among the plurality of additional processes, and allows the power supply for the first signal processing unit so that the image processing apparatus can be switched from the stand-by mode to the normal mode when the first additional process is performed by the second signal processing unit in the stand-by mode.
