Abstract
Techniques for detecting and addressing image flicker are disclosed. An imaging device that senses a distorted image and subsequently removes the distortion during processing can utilize an analysis module that obtains statistics indicative of image flicker prior to removing the distortion. An imaging device that features a diode for illuminating a field of view can utilize the diode as a photosensor to determine one or more flicker statistics to determine whether ambient lighting conditions are of the type that cause image flicker.
Claims21
A device, comprising:
- an image processing hardware element, the image processing hardware element configured to receive:
- first data representing an image that has undergone a distortion correction, and
- second data representing a flicker statistic,
- the image processing hardware element further configured to correct for image flicker according to the flicker statistic and provide output data based on the first data.
A device, comprising:
- an imaging circuit configured to interface to an array of image sensing elements,
- the imaging circuit further configured to, based on output of the array of image sensing elements:
- provide first data representing an undistorted image and generated based on a known distortion of an image sensed by the image sensing elements, and
- provide second data representing a flicker statistic of the image sensed by the image sensing elements.
A method, comprising:
- deriving a flicker statistic from an image having a known distortion;
- and
- generating an undistorted image from the image having the known distortion and providing the undistorted image and the flicker statistic to an image processing element configured to utilize the flicker statistic to correct image flicker.
