An auto-focusing algorithm using discrete wavelet transform |
摘要 |
What is disclosed is a method that includes generating an overall sharpness parameter for a given focus position by performing a Discrete Wavelet Transform upon an image captured by an imaging device and automatically focusing said imaging device to an optimal focus position by comparing a plurality of different sharpness parameters. The optimal focusing position is automatically determined by finding the highest sharpness parameter for a given scene. |
