Abstract
Novel applications for anamorphic lenses in smart glasses. Anamorphic lenses preserve straightness of motion and lines (i.e., “linearity”). As a practical matter, existing computer vision models can be used with anamorphic images without re-training or intermediate conversion steps (unlike fisheye lenses). The contents of the present disclosure provide substantial improvements for applications that have different FOV requirements along different axis. Solutions for ergonomic hand placement (relative to gaze), non-square photosites, binning and eye-tracking are discussed throughout.
Claims20
A smart glasses apparatus, comprising:
- an anamorphic lens characterized by a major axis and a minor axis;
- a photosite array characterized by a major dimension corresponding to the major axis and a minor dimension corresponding to the minor axis, the major dimension larger than the minor dimension;
- a processor;
- and
- a non-transitory computer-readable medium comprising instructions that when executed by the processor, cause the processor to:
- cause the photosite array to capture light information via the anamorphic lens;
- and
- address a subset of the light information according to a scan line of the minor dimension.
A camera module, comprising:
- an anamorphic lens characterized by a major axis characterized by a first magnification and a minor axis characterized by a second magnification smaller than the first magnification;
- and
- a photosite array characterized by a major dimension corresponding to the major axis and a minor dimension corresponding to the minor axis, where the photosite array is addressed as a plurality of one-dimensional data structures according to the minor dimension.
A method, comprising:
- reading a first one-dimensional vector of light information from an anamorphic camera module characterized by a major dimension corresponding to a first axis of an anamorphic lens of the anamorphic camera module and a minor dimension corresponding to a second axis of the anamorphic lens of the anamorphic camera module, the first axis having a greater magnification than the second axis, where the first one-dimensional vector has a first length corresponding to the minor dimension;
- and
- developing the first one-dimensional vector of light information into a one-dimensional vector of pixel values.
