Embodiment Construction

[0040] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0041] In the sighting device, an internal display screen is integrated in the sighting device, and its internal display screen is used to display the target infrared image (obtained through the infrared component) and the target aiming information (obtained through the laser component), and the infrared image displayed on the internal display screen And the aiming information is integrated into the white light component, and the target at night can be observed through the eyepiece of the white light component. Due to the existence of multiple optical paths (white light path, infrared light path, and laser light path), the sight needs to be debugged before use, and it is only observed through the eyepiece video, whic...

Abstract

The invention relates to a homology-based two-channel video synchronous output method and system. The method comprises the following steps: receiving an original video signal in a BT1120 format, and processing the original video signal to obtain 24-bit LCD data; based on the clock synchronization signal, synchronously subjecting the 24-bit LCD data to first-path video output and second-path video output, wherein the process of outputting the first path of video is to output 24-bit LCD data to a first display screen and display the 24-bit LCD data, the process of outputting the second path of video is that the 24-bit LCD data is converted into 16-bit BT1120 data; processing the 16-bit BT1120 data to obtain an SDI video signal; outputting the SDI video signal to a second display screen and displaying the SDI video signal. According to the invention, synchronous output of the first path video and the second path video can be ensured, so that the problem of difficult sighting telescope debugging is solved, and the requirement of obtaining real-time videos is met.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a method and system for synchronously outputting two-channel video based on the same source. Background technique [0002] The multi-functional sight has greatly improved the informatization and intelligent capabilities of the sight by upgrading the original sight with laser ranging, display screen and ballistic software fire control system, and the accuracy of weapon hitting has been improved. However, it also brings difficulties to the debugging of the sight itself. It is not convenient to observe and debug at the same time only through the eyepiece video, which makes the operation more difficult, the debugging process is more complicated, and the ability of the debugging personnel is higher. [0003] Secondly, in combat training, the rear command organization also needs the operator to provide real-time video of the front aiming to visually show the operation situation during t...
