1. A system, comprising:
a first pixel group that detects a change in light intensity;
a second pixel group that detects an amount of light intensity;
a processor to:
receive at least one event signal from the first pixel group;
determine an identity of an object based on the at least one event signal;
determine a degree of interest in the object based on the identity of the object; and
determine an operating mode of the second pixel group based on the degree of interest in the object, wherein the operating mode is one or both of a region of interest and a frame rate of the second pixel group, and wherein the operating mode is different for different degrees of interest in the object.
