Abstract
A method for recovering an image passing through a display and taken by an image sensor disposed on a rear side of the display, the method includes acquiring the image taken by the image sensor, obtaining a plurality of point spread functions corresponding one-to-one to a plurality of dots arranged in a predetermined pattern on a calibration chart, and recovering the image by performing a de-convolution of the image based on the plurality of point spread functions.

A method for recovering an image passing through a display and taken by an image sensor disposed on a rear side of the display, the method comprising:
- acquiring the image taken by the image sensor;
- obtaining a plurality of point spread functions corresponding one-to-one to a plurality of dots arranged in a predetermined pattern on a calibration chart;
- and
- recovering the image by performing a de-convolution of the image based on the plurality of point spread functions.
An electronic device comprising:
- a display;
- an image sensor disposed on a rear side of the display;
- a processor;
- and
- a memory, wherein the processor is configured to recover an image which passes through the display and taken by the image sensor by performing acts of:
- acquiring the image taken by the image sensor;
- obtaining a plurality of point spread functions corresponding one-to-one to a plurality of dots arranged in a predetermined pattern on a calibration chart;
- and
- recovering the image by performing a de-convolution of the image based on the plurality of point spread functions.
A non-transitory computer-readable storage medium, having instructions stored thereon that, when executed by a processor, cause the processor to implement a method for recovering an image passing through a display and taken by an image sensor disposed on a rear side of the display, the method comprising:
- acquiring the image taken by the image sensor;
- obtaining a plurality of point spread functions corresponding one-to-one to a plurality of dots arranged in a predetermined pattern on a calibration chart;
- and
- recovering the image by performing a de-convolution of the image based on the plurality of point spread functions.
