Abstract
A image processing apparatus is provided, the image processing apparatus including: a transmitting terminal; a receiving terminal configured to receive an image signal from the transmitting terminal; a sensor configured to sense whether an image format error occurs in the image signal received in the receiving terminal; and at least one processor configured to control the transmitting terminal to recover the image signal transmitted from the transmitting terminal from the image format error in response to the image format error sensed by the sensor, and to control the receiving terminal to receive the recovered image signal.
Claims16
A image processing apparatus comprising:
- a transmitting terminal configured to transmit an image signal embedded with a clock signal;
- a receiving terminal configured to receive the image signal from the transmitting terminal and to recover the clock signal from the received image signal;
- at least one processor configured to:
- apply jitter to the image signal transmitted from the transmitting terminal to the receiving terminal, wherein the image signal applied with the jitter is deviated in a time axis;
- compare the image signal applied with the jitter and received in the receiving terminal with a reference signal of a predetermined timing standard based on a horizontal resolution value, a vertical resolution value, a horizontal sync signal value, a vertical sync signal value, and a data enable signal value;
- in response to at least one among the values of the image signal applied with the jitter being different from at least one corresponding value of the reference signal, identify that an image format error is in the received image signal;
- and
- control the transmitting terminal to recover the image signal, when it is identified that the image format error occurs.
A method of controlling an image processing apparatus, the method comprising:
- applying jitter to an image signal transmitted from a transmitting terminal, which transmits the image signal embedded with a clock signal, to a receiving terminal which receives the image signal from the transmitting terminal and recovers the clock signal from the received image signal, wherein the image signal applied with the jitter is deviated in a time axis;
- comparing the image signal applied with the jitter and received in the receiving terminal with a reference vertical resolution value, a horizontal sync signal value, a vertical sync signal value, and a data enable signal value;
- in response to at least one among the values of the image signal applied with the jitter being different from at least one corresponding value of the reference signal, identifying that an image format error occurs in the received image signal;
- and
- controlling the transmitting terminal to recover the image signal when it is identified that the image format error occurred.
