Pygame相机条纹/相机图像不可见

如何解决Pygame相机条纹/相机图像不可见

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))
    rotatedOutput1 = pygame.transform.rotate(image1,180)
    rotatedOutput2 = pygame.transform.flip(rotatedOutput1,0)
    pygame.draw.rect(screen,(15,15,15),pygame.Rect(0,300,20))
    pygame.draw.rect(screen,500,150))
    screen.blit(rotatedOutput2,(0,20))

相机上面有线条，我不确定我是怎么做的。我将代码从旧的树莓派转移到了新的树莓派上
