Abstract
Provided are a vision sensor, an image processing device including the same, and an operating method of the vision sensor. The vision sensor includes a pixel array including a plurality of pixels, a synchronization control module configured to receive a synchronization signal from an external image sensor and generate an internal trigger signal based on the synchronization signal, an event detection circuit configured to receive the internal trigger signal and detect whether an event has occurred in the plurality of pixels and generate event signals corresponding to pixels in which the event has occurred, and an interface circuit configured to receive the event signals and transmit to an external processor vision sensor data based on the trigger signal and at least one of the event signals, where the vision sensor data includes matching information for timing image frame information generated by the image sensor and the event signals generated by the vision sensor.
