Classification: CPC G  A | IPC A  G

Claim 8:
9. An auto clean machine control method, comprising:
emitting light to illuminate at least one light region;
sensing a first brightness distribution of the light region by a first image sensing area, wherein a resolution for a horizontal direction of the first image sensing area is higher than a resolution for a vertical direction of the first image sensing area;
sensing a second brightness distribution of the light region by a second image sensing area below the first image sensing area, wherein a resolution for a vertical direction of the second image sensing area is higher than a resolution for a horizontal direction of the second image sensing area;
controlling movement of the auto clean machine according the first brightness distribution and the second brightness distribution;
generating a wall detection result based on the first brightness distribution of the light region;
generating a cliff detection result based on the second brightness distribution of the light region; and
controlling the movement of the auto clean machine according to the wall detection result and the cliff detection result.
