Pass-through display of captured imagery
First Claim
1. A method comprising:
- sequentially outputting from a first imaging sensor each pixel row of a first set of pixel rows of a first image captured by the first imaging sensor;
buffering a subset of the first set of pixel rows in a buffer, the subset including a first pixel row of the first set of pixel rows;
modifying the subset of the first set of pixel rows in the buffer based on augmented reality overlay information associated with a position of the first pixel row to generate a pixel row representative of the first pixel row of the first image;
displaying, at a display device, the pixel row representative of the first pixel row of the first image prior to outputting subsequent rows from the first imaging sensor, the subsequent rows comprising a second pixel row of the first image; and
refraining from performing a second readout of a second image before a first readout of the first image completes.

Abstract
A method includes sequentially outputting from an imaging sensor each pixel row of a set of pixel rows of an image captured by the imaging sensor. The method further includes displaying, at a display device, a pixel row representative of a first pixel row of the captured image prior to a second pixel row of the captured image being output by the imaging sensor. An apparatus includes an imaging sensor having a first lens that imparts a first type of spatial distortion, a display device coupled to the imaging sensor, the display to display imagery captured by the imaging sensor with the first spatial distortion, and an eyepiece lens aligned with the display, the eyepiece lens imparting a second type of spatial distortion that compensates for the first type of spatial distortion.

11. An apparatus comprising:
-
a first imaging sensor having an output to sequentially output pixel rows of a first captured image; a memory buffer configured to receive a subset of a first set of pixel rows from the first imaging sensor, the subset including a first pixel row; a compositor that includes overlay circuitry configured to modify the first pixel row of the subset of the first set of pixel rows in the memory buffer based on augmented reality overlay information to generate a pixel row representative of the first pixel row; and a display controller coupled to the output of the first imaging sensor, the display controller to begin sequential display of pixel rows of the first captured image, including the first pixel row, at a display device before a last pixel row of the first captured image is output by the first imaging sensor, and refraining from performing a second readout of a second captured image before a first readout of the first captured image completes. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
