Abstract

An interactive device of improving image processing. The interactive device includes a processing module and a control circuit. The processing module includes a substrate, an image sensor for generating a plurality of pixel signals, and an estimation unit 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 serially outputting a control signal based on the static parameter determined by the estimation unit. The interactive device also includes a controller for controlling operation of the interactive device based on the control signal based on the static parameters corresponding to each image object. The image sensor, the estimation unit, and the transmission interface are all formed on the substrate.
