IMAGE PROCESSING UNIT, IMAGE PROCESSING APPARATUS AND IMAGE DISPLAY SYSTEM

摘要

An image processing unit including an always on circuit block and a non-always on circuit block is provided. When operating under a first operation mode, the non-always on circuit block receives a bias voltage from a power supply unit, so as to perform an image processing operation on an image input signal. When operating under a second operation mode, the non-always on circuit block stops receiving the bias voltage from the power supply unit, so as to stop the image processing operation, and at least a microcontroller of the non-always on circuit block is powered down. One of the always on circuit block and the non-always on circuit block controls the power supply unit to stop supplying the bias voltage to the non-always on circuit block according an event trigger signal, such that the non-always on circuit block enters the second operation mode from the first operation mode.

1. An image processing unit, comprising:
an always on circuit block, configured to receive a first bias voltage from a power supply unit; and a non-always on circuit block, comprising a microcontroller of the image processing unit, wherein when the non-always on circuit block operates under a first operation mode, the non-always on circuit block receives a second bias voltage from the power supply unit, so as to perform an image processing operation on an image input signal, and when the non-always on circuit block operates under a second operation mode, the non-always on circuit block stops receiving the second bias voltage from the power supply unit, so as to stop the image processing operation, and at least the microcontroller of the non-always on circuit block is powered down; wherein one of the always on circuit block and the non-always on circuit block controls the power supply unit to stop supplying the second bias voltage to the non-always on circuit block according a first event trigger signal, such that the non-always on circuit block enters the second operation mode from the first operation mode.
