FOCUSING METHODS AND APPARATUSES, AND PHOTOGRAPHING DEVICES
First Claim
1. A focusing method, comprising:
- controlling deformation of an image sensor so that reference points of at least two imaging sub-areas of the image sensor after the deformation form a first relative position relationship in a staggered arrangement along a depth direction;
acquiring contrast data of a sampling image of an object in the at least two imaging sub-areas; and
determining and/or adjusting, according to at least the first relative position relationship and the contrast data, a focusing state of the image sensor.

Abstract
The present application discloses various focusing methods and apparatuses, and various photographing devices. The focusing method includes: controlling deformation of an image sensor so that reference points of at least two imaging sub-areas of the image sensor after the deformation form a first relative position relationship in a staggered arrangement along a depth direction; acquiring contrast data of a sampling image of an object in the at least two imaging sub-areas; and determining and/or adjusting, according to at least the first relative position relationship and the contrast data, a focusing state of the image sensor. The present application can improve a speed and/or accuracy for determining and/or adjusting the focusing state of the image sensor.
