The image projection circuitry projects the light beam onto and focuses the light beam on a projection surface located an imaging distance from the image projection circuitry. A time-of-flight sensor is configured to sense the imaging distance between the image projection circuitry and the projection surface and to generate an imaging distance signal indicating the sensed imaging distance. Control circuitry is coupled to the image projection circuitry and to the time-of-flight sensor and is configured to adjust the power and the focus of the light beam based upon the imaging distance signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time of flight sensing for brightness and autofocus control in image projection devices","description":"An image projection device, such as a pico projector or LCD projector, includes image projection circuitry configured to generate a light beam having a power.
