Sony patents circuit to spot timing errors in camera sync signals

Patent drawing from the official filing.

Sony has filed a patent for a circuit that monitors the timing of synchronization pulses used in imaging systems. It uses a counter to measure the time gap between these pulses and flags an error if the interval is incorrect.

Why it mattersThis helps ensure that camera components stay in sync, which is crucial for capturing clear images without glitches.

In the filing’s own words

An abnormality detection circuit according to one embodiment of the present disclosure includes a counter and a determination circuit. The counter is configured to, by performing a counting operation on a basis of pulses corresponding to a synchronization signal, detect a time length between two pulses corresponding to the synchronization signal. The determination circuit is configured to determine an abnormality in the synchronization signal on a basis of a count value of the counter.

What exactly they claim (claim 1)

1. An abnormality detection circuit comprising: a counter configured to, by performing a counting operation on a basis of pulses corresponding to a synchronization signal, detect a time length between two pulses corresponding to the synchronization signal; and a determination circuit configured to determine an abnormality in the synchronization signal on a basis of a count value of the counter.
