Python Pygame相机条纹/相机图像不可见

相机上面有线，我不知道我做了什么导致了这个。 我将我的代码从一个旧的raspberry pi转移到一个新的，这个问题突然出现了

试试这个

pygame.init()
pygame.camera.init()
screen = pygame.display.set_mode((470,420),1, 32)
cam_list = pygame.camera.list_cameras()
cam = pygame.camera.Camera(cam_list[0],(300,300))
cam.start()

PauseControl = 2
Trigger = 1
yPerTick = float(180) / 5 

while Trigger == 1:
    image1 = cam.get_image()
    image1 = pygame.transform.scale(image1,(300,300))
    rotatedOutput1 = pygame.transform.rotate(image1, 180)
    rotatedOutput2 = pygame.transform.flip(rotatedOutput1, 1, 0)
    pygame.draw.rect(screen, (15, 15, 15), pygame.Rect(0, 0, 300, 20))
    pygame.draw.rect(screen, (15, 15, 15), pygame.Rect(0, 300, 500, 150))
    screen.blit(rotatedOutput2, (0,20))
