摘要： A method of detecting a scanning angle range of a laser beam of a laser projector is provided. First, a photo sensor is disposed between first and second positions on a projection mirror. Then, a laser beam emitted from the laser projector scans back and forth between the first and second positions, so that the photo sensor receives the laser beam sequentially at first and second scanning time points to generate first and second sensing signals, respectively. If an actual time interval between the first and second sensing signals conforms to an expected time interval, an actual scanning angle range of the laser beam is determined as normal. If the actual time interval does not conform to the expected time interval, the actual scanning angle range of the laser beam is determined as abnormal and the laser projector stops emitting the laser beam. A laser projector is also provided.

摘要： Teachings herein compose a digital image so that the image is perceptible on a viewing surface, such as a projection surface or a transparent screen. In doing so, the teachings advantageously recognize a digital image as consisting of one or more logical objects, like buttons of a user interface. Often, logical objects may be spatially arranged within the image and/or colored in different possible ways without substantially affecting the meaning conveyed by the image. Exploiting this, teachings herein evaluate light reflected from, or transmitted through, the viewing surface, and compose the digital image from one or more logical objects that have a spatial arrangement or coloration determined in dependence on that evaluation. The teachings might, for example, place a logical object within the image so that it will be displayed on a region of the surface which has high contrast with the object's colors and/or low color variance.

摘要： A projection system uses a transformation matrix to transform a projection image p in such a manner so as to compensate for surface irregularities on a projection surface. The transformation matrix makes use of properties of light transport relating a projector to a camera. A display pipeline of user-supplied image modification processing modules are reduced by first representing the processing modules as multiple, individual matrix operations. All the matrix operations are then combined with, i.e., multiplied to, the transformation matrix to create a modified transformation matrix. The created transformation matrix is then used in place of the original transformation matrix to simultaneously achieve both image transformation and any pre and post image processing defined by the image modification processing modules.

摘要： An image projection method and a projector are provided to be able to change aspect ratio or resolution of a projection image, without setting of keystone correction again. The projector sets a displayable region with a shape according to an aspect ratio and a resolution of the projection image. The projector converts coordinates of the displayable region into coordinates in a screen coordinate system, and generates a rectangular area with a desired aspect ratio in a region corresponding to the displayable region in the screen coordinate system and a portion included in a projecting range. The projector converts the coordinates of a rectangular area into coordinates of a range corresponding to the rectangular area in the panel coordinate system, forms an image in a range corresponding to the rectangular area, and projects the projection image on the screen.
