The projector includes a control device, a projection optical engine, a distance sensing device, and an image capturing device. The projection optical engine projects a first projection image to a projection surface according to first image data. The distance sensing device senses multiple distance parameters of a projection area. The image capturing device captures the first projection image to obtain a first captured image. The control device performs a keystone correction operation and a leveling correction operation on the first image data. The projection optical engine projects a second projection image to the projection surface according to the corrected first image data. The control device obtains a second captured image including the second projection image through the image capturing device, and analyzes the second captured image to project current projection image size information in the second projection image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector and projection method","description":"A projector and a projection method are provided.
