OBJECT DETECTION DEVICE, OBJECT DETECTION SYSTEM, INTEGRATED CIRCUIT FOR OBJECT DETECTION, CAMERA WITH OBJECT DETECTION FUNCTION, AND OBJECT DETECTION METHOD

摘要

An object detection device that shares a bus with an external memory and another device includes: a data acquisition unit that acquires original image data from the external memory via the bus; a reduction processing unit that generates pieces of reduced image data from the original image data at differing reduction rates after the data acquisition unit acquires the original image data once; and an object detection unit that detects a position at which an object appears in the pieces of reduced image data by performing matching processing on the pieces of reduced image data using a template for the object.
