So even on 4 shot the sensor moves? I knew for a 16 shot it moved, but not 4 shot.
For a 4-shot the sensor moves by exactly 1 pixel for each shot:
- 1st shot = initial position, then moves right by 1 pixel
- 2nd shot, then moves down by 1 pixel
- 3rd shot, then moves left by 1 pixel
- 4th shot then moves up by one pixel, to the initial position
The 4-shot captures 2 times the green, 1 time the red and 1 time the blue colour information.
for a 16-shot it moves by 1/2 a pixel each time: 4 times initial position in the left direction , 4 times down, 4 times left, 4 times up to initial position, capturing each 4x4 steps 2 times the green, 1 time the red and 1 time the blue colour information
