Abstract
Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). Software-generated calibration images may be presented on a display having two optics. One or more settings for presentation of the calibration image are adjusted. The settings are related to an inter-pupillary distance (IPD) of the user. An input is received from a user when the user perceives the calibration image to be acceptable at a particular value of the one or more settings. An IPD value that corresponds to the particular value of the one or more settings is then determined. The determined IPD value is used in presenting subsequent software-generated images with the stereoscopic display.
Claims41
A method, comprising:
- presenting a calibration image on a display device having two optics that a user looks into to see a stereoscopic 3D image;
- adjusting one or more settings for presentation of the calibration image with a processor coupled to the display device, wherein the one or more settings are related to an inter-pupillary distance (IPD) of the user;
- receiving an input from the user corresponding to the user perceiving the calibration image to be acceptable at a particular value of the one or more settings at the processor;
- determining an IPD value corresponding to the particular value of the one or more settings with the processor;
- and
- using the determined IPD value in presenting subsequent software-generated images to the stereoscopic display with the processor.
An apparatus, comprising:
- a computer processing system configured, by suitable programming, to perform a method comprising:
- presenting a calibration image on a display device having two optics that a user looks into to see a stereoscopic 3D image;
- adjusting one or more settings for presentation of the calibration image with a processor coupled to the display device, wherein the one or more settings are related to an inter-pupillary distance (IPD) of the user;
- receiving an input from the user corresponding to the user perceiving the calibration image to be acceptable at a particular value of the one or more settings at the processor;
- determining an IPD value corresponding to the particular value of the one or more settings with the processor;
- and
- using the determined IPD value in presenting subsequent images to the stereoscopic display with the processor.
An inter-pupillary distance measuring device, comprising:
- a frame;
- two sighting fixtures movably mounted to the frame, wherein the frame is configured to locate the two sighting fixtures in front of a user's face, wherein the positions of the two sighting fixtures are adjustable to align with a user's eyes;
- and
- a position sensitive device coupled to the two sighting fixtures, the position sensitive device being configured to produce a signal that corresponds to a distance between the two sighting fixtures.
A method comprising:
- displaying a calibration image to a user on a stereoscopic image display device;
- adjusting a display setting of the calibration image, wherein the display setting is dependent upon the user's inter-pupillary distance (IPD);
- receiving an input from the user that corresponds to the display setting of the calibration image being optimized for the user's IPD;
- storing in memory the display setting of the calibration image that is optimized for the user's IPD;
- and
- digitally altering a subsequently displayed image to optimize the subsequently displayed image for the user's IPD based on the stored display setting.
The method of claim 39, wherein said receiving an input from the user that corresponds to the display setting of the calibration image being optimized for the user's IPD includes receiving a timing input from the user that corresponds to a time in the pre-programmed sequence at which the calibration image is perceived to be optimized for the user's IPD.
A system comprising:
- a processor;
- memory coupled to the processor;
- a stereoscopic display device coupled to the processor;
- and
- program instructions embodied in the memory for execution by the processor, the program instructions being configured to implement an IPD adjustment method, the IPD adjustment method comprising any one of the methods of claims 1 through 13 or 21 through 41.
A non-transitory computer readable medium containing program instructions for IPD adjustment, wherein execution of the program instructions by one or more processors of a processing system causes the one or more processors to carry out an IPD adjustment method, the IPD adjustment method comprising any one of the methods of claims 1 through 13 or 21 through 41.
