Earlier versions of Pygame upto 1.9.6 contain pygame.camera module. This module contains functionality to capture camera feed on the game window and grab an image from it. The camera devices available to the system are enumerated in a list returned by list_cameras() method.
pygame.camera.list_cameras()
To initialize a camera object, use camera id, resolution and format arguments.
pygame.camera.Camera(device, (width, height), format)
The default format is RGB. Width and height parameters are by default 640×480.
The camera module has following methods defined in Camera class.
| pygame.camera.Camera.start() | opens, initializes, and starts capturing |
| pygame.camera.Camera.stop() | stops, uninitializes, and closes the camera |
| pygame.camera.Camera.get_controls() | gets current values of user controls |
| pygame.camera.Camera.set_controls() | changes camera settings if supported by the camera |
| pygame.camera.Camera.get_size() | returns the dimensions of the images being recorded |
| pygame.camera.Camera.query_image() | checks if a frame is ready |
| pygame.camera.Camera.get_image() | captures an image as a Surface |
| pygame.camera.Camera.get_raw() | returns an unmodified image as a string |
Example
Following programs captures live feed from computer’s default web camera.
import pygame
import pygame.camera
pygame.init()
gameDisplay = pygame.display.set_mode((640,480))
pygame.camera.init()
print (pygame.camera.list_cameras())
cam = pygame.camera.Camera(0)
cam.start()
while True:
img = cam.get_image()
gameDisplay.blit(img,(0,0))
pygame.display.update()
for event in pygame.event.get() :
if event.type == pygame.QUIT :
cam.stop()
pygame.quit()
exit()
Please note that on Windows OS, you may have to install Videocapture module.
