Abstract
A projector includes a projection device, a capturing device, and a controller. The projection device is configured to project an image beam to form a correction frame. The capturing device is configured to capture a correction frame to generate a captured image frame. The controller is electrically connected to the projection device and the capturing device. The controller receives the captured image frame and adjusts the brightness of the correction frame according to the brightness in the capture area of the captured image frame, and records RGB values of the adjusted correction frame and the capturing parameter of the capturing device after adjusted. An adjustment method for the correction frame of the projector is also provided.
Claims15
A projector, comprising:
- a projection device, a capturing device, and a controller,
- wherein the projection device is configured to project an image beam to form a correction image,
- the capturing device is configured to capture the correction image to generate a captured image,
- the controller is electrically connected to the projection device and the capturing device, wherein
- the controller is configured to receive the captured image and adjust a brightness of the correction image according to a brightness in a capture area of the captured image to form an adjusted correction frame, and record RGB values of the adjusted correction image and a capturing parameter of the capturing device after adjusted,
- wherein an adjustment range of each of the RGB values of the correction image is 1-188.
A projector, comprising:
- a projection device, a capturing device, and a controller,
- wherein the projection device is configured to project an image beam to form a correction image,
- the capturing device is configured to capture the correction image to generate a captured image,
- the controller is electrically connected to the projection device and the capturing device, wherein
- the controller is configured to receive the captured image and adjust a brightness of the correction image according to a brightness in a capture area of the captured image to form an adjusted correction image, and record RGB values of the adjusted correction image and a capturing parameter of the capturing device after adjusted,
- wherein the capturing parameter of the capturing device is unchanged, a brightness of the adjusted correction image is less than the brightness of the correction image, and both the correction image and the adjusted correction image are white images.
A method for adjusting a correction image of a projector, comprising:
- projecting an image beam to form a correction image by a projection device;
- capturing the correction image to generate a captured image by a capturing device;
- and
- adjusting a brightness of the correction image according to a brightness in a capture area of the captured image to form an adjusted correction image, and recording RGB values of the adjusted correction image and a capturing parameter of the capturing device after adjusted,
- wherein an adjustment range of each of the RGB values of the correction image is 1-188.
