Screen recording is a common and useful feature in modern computers. It allows us to capture the activity on the computer screen and save it as a video file or live stream it. In this article, I will introduce how to use programming to implement the computer screen recording function.
Before implementing the computer screen recording function, we need to understand some basic concepts and tools. In Windows operating system, we can use Python programming language and OpenCV library to capture the image on the screen. OpenCV is an open source library widely used for computer vision tasks, which provides many image processing and computer vision functions.
First, we need to install Python and OpenCV libraries. You can download and install Python from the official website. Once the installation is complete, you can install the OpenCV library using the following command:
pip install opencv-python
After the installation is complete, we can start writing code to implement the screen recording function. Here is a simple example code that uses the OpenCV library to capture an image on the screen and save it as a video file:
import cv2
import numpy as np
import pyautogui
# 获取屏幕分辨率
screen_size = (1920, 1080
