Abstract: The invention relates to a method for recognizing surfaces (2), in particular for optically recognizing or identifying structured and/or pictorial surfaces (2), said method involving the steps of —focusing a camera (5) onto a prominent image dot (3) on the surface (2), —creating at least one live video stream of a recognizable, high-contrast area of the image dot (3), and —guiding the camera (5) to the image frame of the video having the greatest depth of detail by focusing a camera (5) onto a prominent image dot (3) on the surface (2) to be sensed, —creating at least two images of a recognizable, high-contrast area of the image dot (3), —storing the image having the greatest depth of detail as a reference image, —analyzing each image frame of the live video stream, —comparing the image frame having the greatest depth of detail with a target image or reference image.

Abstract: The invention relates to a method for assessing contrasts on surfaces (2), in particular for optically identifying structured and/or pictorial surfaces (2), e.g. of paintings (1) or sculptures, said method being simple to use independently of the location and safe. For this purpose, the method involves the steps of—focusing a camera (5) onto a prominent image dot (3) on the surface, —creating at least two images of a recognizable, high-contrast area of the image dot (3), —storing the image having the greatest depth of detail as a reference image.

Abstract: A device for optically identifying surfaces, in particular for optically identifying structured and/or pictorial surfaces, spaces and/or e.g. paintings or sculptures is simple to use independently of the location. For this purpose, the device includes a housing in which light-emitting and light-receiving elements are arranged, and the device also includes a first portion having at least one lens, a portion that follows the first portion in the longitudinal direction and has a screen, and an adjoining handle portion.

Abstract: A system for providing video game specification data includes a display and a control circuit for causing the display to display an interactive form containing data entry fields for inputting game specification data that specifies characteristics of a video game developed for a particular game platform. This system may be part of a game submission system.
