Abstract
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.

- an illuminance estimator configured to estimate illuminance of a light;
- and
- a time delay compensator configured to calculate a time delay between a first time at which the change in the light intensity occurs and a second time at which the first pixel senses the change in the light intensity, based on the illuminance of the light, and to compensate for the time delay.
An electronic device comprising:
- A dynamic vision sensor including a first pixel configured to sense a change in light intensity, and configured to generate a first event signal based on the sensed change in the light intensity;
- an image processing device including a complementary metal-oxide-semiconductor (CMOS) image sensor configured to generate first image data based on an intensity of light;
- an illuminance calculator configured to calculate at least one of illuminance of a light and a change in light illuminance based on the first image data;
- and
- a time delay compensator configured to calculate a time delay between a first time at which the change in the light intensity occurs and a second time at which the first pixel senses the change in the light intensity, based on the at least one of the illuminance of the light and the change in light illuminance, and to generate a second event signal in which the time delay is compensated for,
- wherein the CMOS image sensor includes a second pixel.
An electronic device comprising:
- a camera module group including a plurality of camera modules each generating an electrical signal based on a light reflected from an object;
- and
- an application processor configured to process the electrical signal,
- wherein a first camera module of the plurality of camera modules is implemented with a dynamic vision sensor, and a second camera module of the plurality of camera modules is implemented with an image sensor,
- wherein the first camera module generates an event signal based on a change in light intensity,
- wherein the second camera module generates image data in units of frame,
- wherein the application processor estimates at least one of illuminance of a light and a change in light illuminance based on the image data, and compensates for a time delay between a first time at which the change in the light intensity occurs and a second time at which the first camera module senses the change in the light intensity based on at least one of the illuminance of the light and the change in the light illuminance.
