Abstract
The present disclosure discloses a method, a TV set and a system for recognizing a TV station logo. The method includes: obtaining a TV screen image; for each of a plurality of pre-stored standard TV station logos, selecting a matching area of the standard TV station logo from the TV screen image according to position information of the standard TV station logo, the position information indicating a position of the standard TV station logo in a TV screen; and recognizing a TV station logo in the TV screen image by matching the standard TV station logos with their respective matching areas. The present disclosure reduces the size of the matching area for logo recognition, solves the low speed problem of conventional logo recognition methods due to the selected matching area being large, and brings the effects of reducing the matching area and improving the speed for logo recognition.
