Document Type and Number:
Japanese Patent JP3743094
Kind Code:
B2
Abstract:
A method and apparatus for diagnosing or detecting failures or faults in or between circuits such as signal processing circuits of a video camera system. Predetermined test pattern data may be generated on a first or transmitting side (circuit) and discrimination pattern data having substantially the same data pattern as the test pattern data may be generated on a second or receiving side (circuit) in synchronism with the test pattern data. The test pattern data and the discrimination pattern data may be compared. A failure or faulty spot in or between circuits may be determined in accordance with the results of such comparison.
