有没有办法用 OpenCV 拍照，不使用相机

Question

I am using OpenCV to capture an image from a camera. The camera I'm using a camera that captures static images in 4k, but video in 1080p. Is there a way to take a photo in OpenCV without using videoCapture()?

def takephoto(camNumber):

#This creates two variables, the first one 'date' that records the exact date and time when   the photo was taken and the second one 'imagePath' that records where the image should be stored to
date = datetime.now().strftime("%Y_%m_%d-%I-%M-%S_%p")
imagePath = r'path'

#creates a variable called camera and makes it record what the webcam is displaying
camera = cv2.VideoCapture(camNumber)

#Creates a new variable called image and tells it to record what camera has stored in it at that moment
return_value, image = camera.read()

del(camera)
        
image = NULL
print("Photo Done")
return image, date

I do not think so. other than opencv, you can capture the image using pygame library.

https://www.geeksforgeeks.org/how-to-capture-a-image-from-webcam-in-python/

import pygame
import pygame.camera
  
# initializing  the camera
pygame.camera.init()
  
# make the list of all available cameras
camlist = pygame.camera.list_cameras()
  
# if camera is detected or not
if camlist:
  
    # initializing the cam variable with default camera
    cam = pygame.camera.Camera(camlist[0], (640, 480))
  
    # opening the camera
    cam.start()
  
    # capturing the single image
    image = cam.get_image()
  
    # saving the image
    pygame.image.save(image, "filename.jpg")
