Counter and Timer Control

The Counter function counts up change points in the camera's internal signals using the camera's internal counter and reads that information from the host side. This function verifies error conditions using the count value and internal camera operations. Four counters are available on the camera; Counter0, Counter1, Counter2, and Counter3. The functions that can be counted are fixed for each counter.

When an issue occurs in a system that includes this camera, comparing the values from multiple counters allows you to verify the extent of normal operability and can help investigate the cause.

The following diagram outlines the internal camera blocks:

Use the Counter function by specifying a counter and configuring the following settings:
