Abstract: A auto-focusing method for projection of a computing device with imaging function is illustrated. The computing device exemplarily includes a projection unit, an image receiving unit, and a processing unit. The method firstly controls the projection unit to project images on plural positions along an optical axis.

The candidate images correspond to the projective positions. The method further receives the candidate images captured by the image receiving unit, and compute their definitions. Therefore, the image with a greatest definition may be acquired and regarded as a focus image. The focus image's corresponding position is a focus position. After acquiring the focus position, an image may be projected thereon. The illustrated computing device is enabled to complete the image focusing automatically.
