Abstract
A recovery circuit including: a first circuit configured to detect an abnormal signal based on an input signal and mask a signal subsequent to the abnormal signal when the input signal is detected as the abnormal signal; a second circuit configured to receive the abnormal signal from the first circuit, generate a fake signal in response to the abnormal signal, and transmit the fake signal to a processor; and a third circuit configured to generate a control signal and transmit the control signal to the processor; wherein the processor ignores the abnormal signal and performs an image processing operation based on the fake signal in response to the control signal.
Claims20
A recovery circuit comprising:
- a first circuit configured to detect an abnormal signal based on an input signal and mask a signal subsequent to the abnormal signal when the input signal is detected as the abnormal signal;
- a second circuit configured to receive the abnormal signal from the first circuit, generate a fake signal in response to the abnormal signal, and transmit the fake signal to a processor;
- and
- a third circuit configured to generate a control signal and transmit the control signal to the processor;
- wherein the third circuit is configured to control the processor to perform an image processing operation based on the fake signal.
A method of operating an image processing apparatus including an image sensor, the method comprising:
- receiving an input signal including a plurality of frame sections from the image sensor and detecting an abnormal signal in a first frame section of the input signal;
- masking a second frame section of the input signal when the abnormal signal is detected in the first frame section;
- generating a fake signal corresponding to the first frame section after masking the second frame section;
- and
- generating an output image in response to the fake signal,
- wherein the second frame section is received after the fake signal is terminated, and
- wherein the second frame section is subsequent to the first frame section.
