Embodiment Construction

[0048] Please refer to Figure 4 As shown, it is a schematic structural diagram according to an embodiment of the present invention. The present invention discloses a projection device 100 that automatically adjusts the imaging size. The projection device 100 described in this embodiment is a projector, but those skilled in the art should be able to apply it to other electronic devices with a projection function, so they are not listed one by one. The projection device 100 projects the image signal on the screen 190 with a corresponding imaging size according to the input image size. The projection device 100 includes: an input unit 120 , a detection unit 170 , an image receiving unit 110 , a lookup table 140 , a displacement unit 180 , a processing unit 150 and an optical engine 160 .

[0049] Wherein, the image size is input by the user. Generally speaking, the projection device 100 can display options for the user to choose, such as 29×21 cm (A4), 50×35 cm (B3), 59×42 cm ...

Abstract

The invention relates to projecting device and method for automatically adjusting an imaging size. The projecting device projects an image signal on a screen in a corresponding imaging size according to the input image size and comprises an input unit, a detecting unit, an image receiving unit, a searching table, a shifting unit, a processing unit and an x-ray apparatus, wherein the input unit receives the image size; the detecting unit detects an initial space parameter between the projecting device and a screen; and the processing unit searches a corresponding preset size, a preset space parameter, a preset optical parameter and a preset image parameter in the searching table according to the image size, drives the shifting unit to adjust the position of the projecting device according to the preset space parameter and the initial space parameter, processes an image signal received by the image receiving unit according to the preset image parameter and controls the x-ray apparatus to project the imaging size on the screen according to the preset optical parameter.

Description

technical field [0001] The invention relates to a projection device, in particular to a projection device and method for automatically adjusting imaging size. Background technique [0002] Since the projection device (projector) was invented, it has been applied to various fields with the development of technology, from consumer products to high-tech products, and its application range has been expanding. , or a projection screen or TV used in business, to present instant image images in conjunction with the content of the briefing. [0003] Please refer to figure 1 As shown, it is a schematic projection diagram of a known projection device. When the projection device 10 is in use, it projects images onto a projected surface (or called a screen) 12 for users to watch. Generally speaking, when the projection result is proper, the projection line 14 is perpendicular to the projected surface 12 . [0004] Please refer to figure 2 As shown, it is a side view of a known pro...
