A projector control method with an environment adaptive function and applied to a projector device, the projector control method comprising:
- an operation processor of the projector device driving a projection lens to project a dark-colored projection image onto a projection curtain;
- the operation processor utilizing an image detector to acquire a detection image relevant to the dark-colored projection image;
- the operation processor acquiring an ambient light intensity based on the image detector configured to capture the dark-colored projection image and an ambient light sensor;
- the operation processor driving the projection lens to project a bright-colored projection image onto the projection curtain;
- the operation processor utilizing the image detector to acquire the detection image relevant to the bright-colored projection image;
- the operation processor acquiring an image intensity of the detection image relevant to the bright-colored projection image based on the bright-colored projection image and the ambient light intensity;
- the operation processor driving a size detector to acquire a size of the detection image on the projection curtain;
- and
- the operation processor acquiring a control parameter combination in accordance with the size of the detection image, the ambient light intensity and the image intensity to adjust an intensity, color temperature or color of the projection image.
A projector device with an environment adaptive function, the projector device comprising:
- a projection lens adapted to alternately project a dark-colored projection image and a bright-colored projection image onto a projection curtain;
- an image detector adapted to alternately acquire detection images relevant to the dark-colored projection image and the bright-colored projection image;
- a size detector adapted to acquire a size of the detection image on the projection curtain;
- an ambient light sensor;
- and
- an operation processor electrically connected with the projection lens, the image detector, the size detector and the ambient light sensor, the operation processor being adapted to acquire an ambient light intensity based on the image detector configured to capture the dark-colored projection image and the ambient light sensor, acquire an image intensity of the detection image relevant to the bright-colored projection image based on the bright-colored projection image and the ambient light intensity, and acquire a control parameter combination in accordance with the size of the detection image, the ambient light intensity and the image intensity for adjusting an intensity, color temperature or color of the projection image.
