Abstract

An interactive device for improving image processing. The interactive device includes a processing module and a controller. The processing module includes a substrate, an image sensor formed on the substrate for generating a plurality of pixel signals, a calculation unit formed on the substrate for calculating at least one motion vector based on the plurality of pixel signals, and a transmission interface formed on the substrate for serially outputting the motion vector. The controller is used for controlling operation of the interactive device based on the motion vector output by the transmission interface

Claims

1. An interactive device capable of improving image processing comprising:

a processing module comprising;

a substrate;

an image sensor, formed on the substrate, for generating a plurality of pixel signals;

a calculation unit, formed on the substrate, for calculating at least one motion vector based on the plurality of pixel signals, wherein the motion vector is calculated as a motion difference between a reference object and a target object, the target object being a set of pixel signals in a target image picture, and the reference object being an object in a searching area of a previous image picture or a following image picture with respect to the target image picture that has a size similar to that of the target object and that has the smallest difference with respect to the target object; and

a transmission interface, formed on the substrate, for serially outputting a control signal based on the motion vector; and

a controller for controlling operation of the interactive device based on the control signal.

2. The interactive device of the claim 1 wherein the transmission interface is a universal asynchronous receiver/transmitter (UART).

3. The interactive device of the claim 1 wherein the transmission interface is I²C interface.

4. The interactive device of the claim 1 wherein the image sensor is a CMOS sensor.

5. The interactive device of the claim 1 wherein the image sensor is a charge-coupled device (CCD).
