Abstract
The invention provides an image processing method and device to determine whether the timing signal is abnormal by detecting timing signal related to the image signal output to the display. When the timing signal is abnormal, the display receives no the timing signal related to the image signal. The horizontal synchronous signal and vertical synchronous signal prevent the elements in the display, such as electron gun, from operating with abnormal signals, enhancing display lifetime.
Claims26
An image processing method, comprising:
- detecting a timing signal associated with an image signal for input to a display;
- determining if the timing signal is abnormal;
- and
- stopping the display to receive a synchronous signal associated with the image signal when the timing signal is abnormal.
An image processing device, comprising:
- a clock state detecting device, detecting a first clock signal to output a first detecting result signal based on the state of the first clock signal;
- and
- an output state control device, receiving a first synchronous signal and a second synchronous signal to determine whether to output a horizontal synchronous signal and a vertical synchronous signal to the display based on the first detecting result signal.
An image processing device, comprising:
- a clock state detecting device, detecting a first clock signal and a second clock signal to output a first detecting result signal based on the state of the first clock signal and the second clock signal;
- and
- an output state control device, receiving a first synchronous signal and the second synchronous signal to determine whether to output a horizontal synchronous signal and a vertical synchronous signal to the display based on the first detecting result signal.
