An image processing device includes a vision sensor and a processor. The vision sensor generates a plurality of events in which an intensity of light changes and generates a plurality of timestamps depending on times when the events occur. In addition, the processor may regenerate a timestamp of a pixel where an abnormal event occurs, based on temporal correlation of the events.

Image processing device configured to regenerate timestamp and electronic device including the same

An image sensor includes a CIS (CMOS image sensor) pixel, a DVS (dynamic vision sensor) pixel, and an image signal processor. The CIS pixel includes a photoelectric conversion device generating charges corresponding to an incident light and a readout circuit generating an output voltage corresponding to the generated charges. The DVS pixel detects a change in an intensity of the incident light based on the generated charges to output an event signal and does not include a separate photoelectric conversion device. The image signal processor allows the photoelectric conversion device to be connected to the readout circuit or the DVS pixel.

Disclosed is an electronic device which includes a dynamic vision sensor that includes a first pixel sensing a change in light intensity and generates an event signal based on the sensed change in light intensity, an illuminance estimator that estimates illuminance of a light, and a time delay compensator that calculates a time delay between a first time at which the change in light intensity occurs and a second time at which the first pixel senses the change in light intensity, based on the illuminance of the light, and to compensate for the time delay.

Electronic device for compensating for time delay of dynamic vision sensor

A sensor includes a determining circuit and an output circuit. The determining circuit receives a first signal from a pixel in response to light and outputs a second signal associated with occurrence of an event, based on the first signal. Based on the second signal being received in a time period between a first time when a third signal is received from a processor and a second time when a condition is satisfied, the output circuit outputs a fourth signal associated with occurrence of the event in the time period to the processor after the second time.

A method of extracting a static pattern from an output of an event-based sensor. The method may include receiving an event signal from the event-based sensor in response to dynamic input, and extracting a static pattern associated with the dynamic input based on an identifier and time included in the event signal. The static pattern may be extracted from a map generated based on the identifier and time.
