One end of the A310, and the second tube A200 does not include the ring edge A21〇< One end penetrates from the other end of the through hole A310 to be screwed to the first pipe member A1. In addition, a digital image display device A400 is disposed on the side of the second tube member A200 including the edge A210, and the second tube member A200 is coupled to the digital image display device by the body A5. The digital image display device A400 is provided with a lens A410, which can receive the image from the lens A110, and send the image to a photosensitive element (not shown) inside the digital image display device A400, thereby converting the image into The digital image can be output and displayed in the end. [0004] Referring next to the second figure, a schematic image of one of the original images is captured by the conventional digital door device. As shown in the figure, the 100101365 form number A0101 page 3 / 28 pages 1002002413-0 201229378 The original image B system contains an actual imaging area B1 〇〇 (ie photosensitive area) and a non-photosensitive area B200 'the actual imaging area B100 is located approximately in the original image. At the same time, except for the actual imaging area B1 00, the remaining areas in the original image B are the photosensitive areas B200. The reason for this phenomenon is that the image taken through the lens All in the first tube A100 is only projected on the central portion of the lens A410 of the digital image display device A400, and the area around the lens A410 is first. The wall of the tube A100 and the wall of the second tube A200 are shielded from the rim A210, so that the surrounding area of the lens A410 cannot project light into the photosensitive element, causing the original image B to be in addition to the central turbulent imaging area B100. The other areas are dark, non-photosensitive areas B200. Although the original image B containing the photosensitive area B200 can still display the image outside the door normally, it is very difficult for the user to stare at the central actual imaging area B1 00 in a wide range of non-photosensitive area B200. It is easy to cause eye fatigue. [0005] In view of the above, it is necessary to provide an image processing method for a digital door device, whereby an appropriate size area is extracted from the actual imaging area, so that the user can more easily view the #image, and is no longer subject to darkness. No interference from the photosensitive area affects the viewing of the image.

After the present invention has been described in detail through the above, it can be seen that the present invention has the following advantages: 100101365 Form No. A0101 Page 9 / Total 28 I 1002002413-0 [0016] 201229378 [0017] 1. The present invention is processed by image processing The method extracts an appropriate size range from the actual imaging area, so that the user can view the image more easily, and is no longer affected by the dark non-photosensitive area to affect the image viewing. 2. The present invention utilizes the firmware and software layers for digital image processing, which can be achieved without changing the hardware structure, thereby saving a lot of product development costs. 3. The invention can achieve image capturing by a plurality of image processing methods, and can adopt different corresponding processing methods according to different situations, so that the application has great flexibility. The embodiments described above are merely illustrative of the technical spirit and characteristics of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the contents of the present invention and to implement the patents of the present invention. Scope, if varied or modified in accordance with the spirit of the invention, is intended to be included within the scope of the invention.
