Abstract
Aspects of the present disclosure relate to systems and methods for compensating for camera motion during an autofocus operation. An example device may include a processor and a memory. The processor may be configured to measure a plurality of focus values. Each focus value is measured at a different focal length. The processor also may be configured to detect that a camera motion exists for the measurement of one or more of the plurality of focus values. The processor further may be configured to determine a focal length based on the plurality of measured focus values and the detected camera motion.
Claims16
A device, comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- measure a plurality of focus values during an autofocus operation for a camera, wherein each focus value is measured at a different focal length;
- detect that a camera motion exists for the measurement of one or more of the plurality of focus values;
- adjust a measured focus value for which the camera motion is detected based on an average of the measured focus value for which the camera motion is detected and one or more other focus values of the plurality of measured focus values;
- and
- determine a focal length based on the plurality of measured focus values and the adjusted focus value.
A method, comprising:
- measuring a plurality of focus values during an autofocus operation for a camera, wherein each focus value is measured at a different focal length;
- detecting that a camera motion exists for the measurement of one or more of the plurality of focus values;
- adjusting a measured focus value for which the camera motion is detected based on an average of the measured focus value for which the camera motion is detected and one or more other focus values of the plurality of measured focus values;
- and
- determining a focal length based on the plurality of measured focus values and the adjusted focus value.
A non-transitory computer-readable medium storing one or more programs containing instructions that, when executed by one or more processors of a device, cause the device to:
- measure a plurality of focus values during an autofocus operation for a camera, wherein each focus value is measured at a different focal length;
- detect that a camera motion exists for the measurement of one or more of the plurality of focus values;
- adjust a measured focus value for which the camera motion is detected based on an average of the measured focus value for which the camera motion is detected and one or more other focus values of the plurality of measured focus values;
- and
- determine a focal length based on the plurality of focus values and the adjusted focus value.
A device, comprising:
- means for measuring a plurality of focus values during an autofocus operation for a camera, wherein each focus value is measured at a different focal length;
- means for detecting that a camera motion exists for the measurement of one or more of the plurality of focus values;
- means for adjusting a measured focus value for which the camera motion is detected based on an average of the measured focus value for which the camera motion is detected and one or more other focus values of the plurality of measured focus values;
- and
- means for determining a focal length based on the plurality of focus values and the adjusted focus value.
