Abstract
A focusing method includes obtaining a first image, determining a focusing area from the first image, performing a digital zoom process on the focusing area according to a zoom-in ratio to obtain a second image, and performing a focus process on the second image.
Claims20
A focusing method comprising:
- obtaining, by a processor, a first image;
- determining, by the processor, a focusing area from the first image, the focusing area comprising at least one pixel;
- performing, by the processor, a digital zoom process on the focusing area according to a zoom-in ratio to obtain a second image comprising a plurality of original pixels from the focusing area and an interpolated pixel, performing the digital zoom process comprising:
- determining N reference original pixels from the plurality of original pixels according to the zoom-in ratio and a position of the interpolated pixel in the second image, a position of one of the N reference original pixels in the focusing area corresponding to the position of the interpolated pixel in the second image, and N being an integer equal to or larger than 1;
- and
- performing, by the processor, a focus process on the second image according to the interpolated pixel and the N reference original pixels.
