Patent Images
1. A home appliance control device for controlling an operation state of a home appliance, the home appliance control device comprising:
- a first image sensor comprising a variable aperture or a variable focus, and configured to acquire a plurality of current images of at least one active object through the variable aperture or the variable focus, wherein every current image corresponds to a different aperture value or focus value;
a processing unit configured tocontrol the first image sensor to acquire the current images respectively according to different focus values,identify a clearest current image to accordingly determine a static parameter associated with the active object and to obtain a dynamic parameter associated with the active object by comparing the current images, wherein the clearest current image is the current image having smallest point spread functions or sharpest edges; and
a control unit for controlling the operation state of the home appliance according to the static parameter and the dynamic parameter.
