Reset Exposure Alignment Overview
Sensor timing is reset to initiate exposure when a valid trigger is received. Readout is sequential to
exposure, reducing the maximum achievable frame rates. That is, a trigger received during
exposure or readout is ignored since data would be lost by performing a reset.
Exposure Timing for Sony Models
Sony sensor models support both Synchronous Mode and Reset Mode exposure alignment. Timing
diagrams and relevant specifications are specified below.
