The PlayStation Eye is capable of capturing standard video with frame rates of 60 hertz at a 640×480 pixel resolution, and 120 hertz at 320×240 pixels,[1] which is "four times the resolution" and "two times the frame-rate" of the EyeToy, according to Sony.[10] Higher frame rate, up to 320x240@187 or 640x480@75 fps, can be selected by specific applications (Freetrack and Linuxtrack).
