Abstract
A method for providing a simulation of a vision defect is disclosed. The method includes: receiving a first image of a scene and a second image of the scene, the first image corresponding to a first viewpoint of the scene and the second image corresponding to a second viewpoint of the scene; applying one or more first distortions to only a selected one of the first and second images; generating a stereoscopic image by merging the distorted one of the first and second images and an undistorted one of the first and second images; and displaying the stereoscopic image on a display.
Claims15
A processor-implemented method for providing a simulation of a vision defect, comprising:
- receiving a first image of a scene and a second image of the scene, the first image corresponding to a first viewpoint of the scene and the second image corresponding to a second viewpoint of the scene, wherein the first image is received from a first camera and the second image is received from a second camera, the first camera and the second camera being mounted on a device worn by a user and being directed at the scene;
- receiving parameters indicating at least one of magnitude and location of one or more first distortions to apply to one of the first and second images, the one or more first distortions simulating at least one visual effect associated with the vision defect and the parameters being customized according to patient-specific vision defect data;
- applying the one or more first distortions to only a selected one of the first and second images, the one or more first distortions being controlled according to the received parameters;
- generating a stereoscopic image by merging the distorted one of the first and second images and an undistorted one of the first and second images;
- and
- displaying the stereoscopic image on a near-eye display mounted on the device worn by the user.
An electronic device for simulating visual effects of a vision defect, comprising:
- a near-eye display mounted on a device worn by a user;
- and
- a processor coupled to the near-eye display, the processor being configured to:
- receive a first image of a scene and a second image of the scene, the first image corresponding to a first viewpoint of the scene and the second image corresponding to a second viewpoint of the scene, wherein the first image is received from a first camera and the second image is received from a second camera, the first camera and the second camera being mounted on the device worn by the user and being directed at the scene;
- receive parameters indicating at least one of magnitude and location of one or more first distortions to apply to one of the first and second images, the one or more first distortions simulating at least one visual effect associated with the vision defect and the parameters being customized according to patient-specific vision defect data;
- apply the one or more first distortions to only a selected one of the first and second images, the one or more first distortions being controlled according to the received parameters;
- generate a stereoscopic image by merging the distorted one of the first and second images and an undistorted one of the first and second images;
- and
- display the stereoscopic image on the near-eye display.
A non-transitory computer-readable medium containing processor-executable instructions for providing a simulation of a vision defect, wherein the instructions, when executed, cause a processor to:
- receive a first image of a scene and a second image of the scene, the first image corresponding to a first viewpoint of the scene and the second image corresponding to a second viewpoint of the scene, wherein the first image is received from a first camera and the second image is received from a second camera, the first camera and the second camera being mounted on a device worn by a user and being directed at the scene;
- receive parameters indicating at least one of magnitude and location of one or more first distortions to apply to one of the first and second images, the one or more first distortions simulating at least one visual effect associated with the vision defect and the parameters being customized according to patient-specific vision defect data;
- apply the one or more first distortions to only a selected one of the first and second images, the one or more first distortions being controlled according to the received parameters;
- generate a stereoscopic image by merging the distorted one of the first and second images and an undistorted one of the first and second images;
- and
- display the stereoscopic image on a near-eye display mounted on the device worn by the user.
