The method comprises steps: using a detection module to capture images of a driver and measure a distance between the detection module and the driver; recognize facial features of a driver (including a position of the driver's eye, a rotation angle of the driver's face, and a direction the driver fixates) to estimate a required displacement of the projection area on the windshield (i.e. the region inside the visual field of the driver); moving or rotating the projection device according to the required displacement of the projection area to make the projection device project images of driving information onto a correct region on the windshield.

  • Patent number: 9091906
    Abstract: A projector may include an imaging unit, a positional-information generating unit, and a projecting unit. The imaging unit picks up an image of a projection target area with light in a first wavelength band and generates a first pickup image and picks up an image of the projection target area with light in a second wavelength band and generates a second pickup image. The positional-information generating unit generates, on a basis of the first pickup image, adjustment data for performing adjustment of positional information indicating a position of indication light and generates, on a basis of the second pickup image, the positional information. The projecting unit projects an image based on the positional information.

  • Patent number: 9082186
    Abstract: The distance between projection coordinates to which the center of an image are projected and the center coordinates are added to the projection coordinates to obtain projection center coordinates. The distance is added to the coordinates to which the four corners of the image are projected to obtain projection four-corner coordinates. A distance shorter than the minimum of the distances between the projection four-corner coordinates and the projection center coordinates is decided as an output margin distance. Projection source coordinates to be projected to coordinates apart from the projection center coordinates by the output margin distance are obtained. A maximum of the distances between the projection source coordinates and the projection center coordinates is decided as an input margin distance. Divided images decided based on ½ of horizontal size of the image and the input margin distance are deformed and outputted.

    Abstract: A projector includes a main body including a projection unit which projects an image, a movement detecting unit which detects movement of the main body, and an imaging unit which captures an image of a screen. Furthermore, the projector includes a correction control unit which performs trapezoidal distortion correction on the basis of an image-capturing result, and a second processing unit which performs a second process, which is different from the trapezoidal distortion correction, on the basis of the image-capturing result. In a case where it is determined that the main body is moving on the basis of a detection result, an imaging control unit allows the correction control unit to perform the trapezoidal distortion correction, and in a case where it is determined that the main body is stopped, the imaging control unit allows a manipulation detecting unit to perform a manipulation detecting process.

    Abstract: Methods, systems, and computer-readable media for generating a projected image are provided. Movement measurements are received from an accelerometer within a projection device. A determination is made as to whether the movement measurements indicate movement of the projection device. Upon determining that the movement measurements indicate movement of the projection device, a movement correction factor is determined based on the movement measurements to compensate for the movement of the projection device. The projection device is caused to generate a projected image according to the movement correction factor.

    Abstract: Described is a dynamic correction of keystone distortions of a dynamically panning and tilting luminaire projecting on a flat projection surface. When the luminaire is panned and/or tilted the proper degree of keystone correction is applied. Further the system dynamically corrects for varying of intensity of different parts of the projected image due to the none linear distribution of light on the projection surface as the luminaire is dynamically panned and or tilted relative to the projection surface.
