A projection system and a projection method are provided. The projection system includes a first projector and a second projector. The first projector is configured to project a first grid picture onto a projection surface. The second projector is configured to project a second grid picture onto the projection surface. The second grid picture and the first grid picture are blended into a blended projection picture. The first grid picture includes a first overlap region. Grid lines of the first overlap region are displayed in a first color. The second grid picture includes a second overlap region. Grid lines of the second overlap region are displayed in a second color. The first color and the second color are complementary colors. When the blended projection picture is formed, grid lines of an overlap region of the first grid picture and the second grid picture are displayed in a recognition color.

Projection system and projection method

A projection positioning system and a projection positioning method thereof are provided. A projection device projects a first test image and a second test image on a projection screen based on a projection range at different time points. At least one photosensitive element is disposed on the projection screen. In response to projecting the first test image, a computing device divides a first image sub-zone of the first test image according to the first image sub-zone corresponding to one of first optical parameters sensed by the photosensitive element, to generate the second test image. In response to projecting the second test image, the computing device determines positioning information of the photosensitive element with respect to the projection range according to a second image sub-zone corresponding to one of second optical parameters sensed by the photosensitive element. The projection device performs a projection adjustment function according to the positioning information.

Projection positioning system and projection positioning method thereof

A projection system, a projection image adjusting method and a projector are provided. The projection system includes a projector and a control unit. The projector projects a projection image. The control unit controls movement of an image grid point of the projection image projected by the projector. When the projector receives a continuous adjustment signal output by the control unit, the projector determines a cumulative displacement amount proportional to a continuous signal quantity cumulative value according to the continuous signal quantity cumulative value of the continuous adjustment signal, and the image grid point is moved by the projector according to the cumulative displacement amount to correspondingly deform at least a part of the projection image, so as to provide a convenient projection image adjustment effect.

Projection system, projection image adjusting method and projector

A projection device having a signal input unit, an image signal generating unit, an image adjustment unit, a control unit and a projection unit is provided. The signal input unit receives an external signal. The image signal generating unit generates an image signal. The image adjustment unit generates image adjustment gridlines according to the signal source. The control unit detects the signal input unit, and when the signal input unit does not receive the external signal, the control unit controls the image signal generating unit to generate the image signal to serve as the signal source. The projection unit projects the signal source and the image adjustment gridlines onto a projection plane. The projection device and the method for generating adjustment gridlines of the invention are still capable of generating the image adjustment gridlines in case that an input signal source does not exist.
