Abstract

An interactive device includes an image sensor for generating a plurality of pixel signals, and a processor for determining a static parameter of at least one image object of the image based on the plurality of pixel signals. A transmission interface is used for outputting a control signal based on the static parameter determined by the processor.

Claims

a transmission interface for outputting at least one output signal.

2. The interactive device of claim 1, wherein the static parameter set comprises one or more parameters from a group comprising a coordinate of an gravity center of an image object, an area of the image object, a direction indicating the image object orientation, an average color of the image object, coordinates of some specified object points of the image object, a length to width ratio of the image object, a shape of the image object, and boundaries of the image object.

3. The interactive device of claim 2, wherein the some specified object points of the image object indicate corner points or high curvature points of the image object.

4. The interactive device of claim 1, wherein the output signal comprises at least one parameter from the at least one image object.

6. The interactive device of claim 1, wherein the output signal comprises a motion vector calculated in any combination of at least two parameters from the at least two image objects.

7. The interactive device of claim 4, wherein the parameters of the image objects comprise the one or more parameters from the group comprising the coordinate of the gravity center of the image object, the area of the image object, the direction indicating the image object orientation the average color of the image object, coordinates of some specified object points of the image object, the length to width ratio of the image object, the shape of the image object, and the boundaries of the image object.

8. The interactive device of claim 5, wherein the parameters of the image objects comprise the one or more parameters from the group comprising the coordinate of the gravity center of the image object, the area of the image object, the direction indicating the image object orientation the average color of the image object, coordinates of some specified object points of the image object, the length to width ratio of the image object, the shape of the image object, and the boundaries of the image object.

9. The interactive device of claim 6, wherein the parameters of the image objects comprise the one or more parameters from the group comprising the coordinate of the gravity center of the image object, the area of the image object, the direction indicating the image object orientation the average color of the image object, coordinates of some specified object points of the image object, the length to width ratio of the image object, the shape of the image object, and the boundaries of the image object.

10. The interactive device of claim 1, wherein the transmission interface is selected from a group comprising an I²C interface, a universal serial bus (USB) interface, a wireless USB inter face, a serial peripheral interface (SPI), a universal asynchronous receiver/transmitter (UART) interface, and a parallel transmission interface.
