Changing the camera and camera resolution
The following table shows how the speed of the sketch mode compares on Raspberry Pi 2 using different types of cameras and different camera resolutions:
| Hardware | 640 x 480 resolution | 320 x 240 resolution |
| Raspberry Pi 2 with Raspberry Pi Cam | 3.8 FPS | 12.9 FPS |
| Raspberry Pi 2 with PS3 Eye webcam | 3.2 FPS | 11.7 FPS |
| Raspberry Pi 2 with unbranded webcam | 1.8 FPS | 7.4 FPS |
As you can see, when using the Raspberry Pi Cam in 320 x 240, it seems we have a good enough solution to have some fun, even if it's not in the 20-30 FPS range that we would prefer.
