Abstract: A projection apparatus includes a light valve, a lens module, a distance measuring module, a lens position detection module and a processor. The light valve forms an image beam. The lens module projects the image beam onto a display surface. The distance measuring module detects a distance between the lens module and the display surface to obtain a first distance value. The lens position detection module detects a position of the lens module to obtain a second distance value. The processor receives the first distance value from the distance measuring module, receives the second distance value from the lens position detection module and obtains an effective focus range according to the second distance value.

Abstract: A projection system and a keystone correction method are provided. The projection system includes: a projector projecting an image to a projection zone; an image capturing device capturing a captured image including the projection zone; and a processor. The processor divides the captured image into multiple focusing zones, and controls a stepper motor to shift focusing on the focusing zones at edges to obtain a step of the stepper motor and a distance for each of the focusing zones with a maximum clarity value. The distance is a projection distance between a lens module and the focusing zone. The processor calculates an included angle between the direction of a light axis of the projector and the projection zone according to the distances of the focusing zones at the edges, and performs a warping operation on a projection image according to the included angle.

Abstract: A decorative and connectable display arrangement that includes a housing of multi-sided form having opposed first and second sides and a bottom, an inner support frame that is disposed within the housing and including a cap member having an open top port, and at least one decorative member that is supported within the housing and extends upwardly through the open top port. The decorative member includes a base piece that is pivotally supported in the housing and a stem piece extending from the base piece and extending through the open top port. A solar energy source or panel is supported in the inner support frame and is effective for driving the at least one decorative member in a predetermined motion direction. The housing has 3 on opposed sides thereof an interlock tongue and groove mechanism that enables adjacent ones of the housings to be engaged together.

Abstract: A projector includes a projection lens, an image capture module and a processor. The projection lens projects a projection image onto a display surface. The image capture module is disposed on one side of the projection lens and captures an image frame covering the projection image and defines a plurality of zones on the image frame. The zones correspond to parts of the image frame and cover at least the projection image and do not cover the entire image frame. The image capture module analyzes the parts of the image frame to obtain image data including a plurality of respective zone values. The processor is electrically connected to the image capture module and receives the image data and adjusts a focal length of the projection lens according to at least two of these zone values selected based on the image data. A focal length adjusting method is also provided.
