An image processing device is provided, which has an improved face detection method. The image processing device may include a background manager, which determines a foreground region having a target object and a background region which excludes the target object based on image data that includes pixel values of pixels included in the image and depth map data that includes disparity values of the image pixels; and a target object manager determines a reference position of the target object by counting foreground pixels included in the foreground region in a preset direction at a plurality of positions, and detecting the target object corresponding to a preset shape within a region of interest that is set based on the reference position.

Image processing device and face detection method

A method for testing a focusing characteristic of a camera may include setting a camera to align the camera and a first chart structured to provide a first scene for testing such that the camera is focused on the first chart disposed at a first distance from the camera, measuring a blur in an image of a second chart captured at a second distance from the camera, the second chart being structured to provide a second scene for testing, and evaluating a phase difference range (PDR) of the camera based on the measured blur and a blur calculated through a circle of confusion (CoC) model.
