1. An apparatus for analyzing an image, the apparatus comprising: a memory configured to store computer-readable instructions; and a processor configured to execute the computer-readable instructions, which when executed cause the processor to implement: a classifier configured to receive an event signal corresponding to at least one pixel of an event-based vision sensor in which an event is detected, and configured to determine a pattern of a pixel group of a plurality of pixels of the event-based vision sensor including the at least one pixel and a plurality of adjacent pixels of the event-based vision sensor adjacent to the at least one pixel based on pixel types of the plurality of adjacent pixels, wherein the classifier compares a difference, between a time stamp of a time at which the event is detected by an adjacent pixel included in the pixel group and a time stamp of a time at which the event is detected by the at least one pixel included in the pixel group, with a threshold, and classifies a pixel type of the adjacent pixel included in the pixel group as a predetermined pixel type corresponding to the comparison result, from among a plurality of predetermined pixel types; and an analyzer configured to determine at least one of an appearance of the object and movement of the object, based on the pattern of the pixel group.
