each of the first, second and third apertures being focused at its respective focus range;
the plurality of apertures configured for simultaneously generating electronic image data, the electronic image data including an image generated by the first aperture, an image generated by the second aperture, and an image generated by the third aperture, the first aperture-generated image, the second aperture-generated image and the third aperture-generated image depicting a scene, a near region of the scene being in focus in the first aperture-generated image and being out-of-focus in the second aperture-generated image and the third aperture-generated image, a far region of the scene being out-of-focus in the first aperture-generated image and being in focus in the second aperture-generated image and the third aperture generated image;
a computer being coupled to said plurality of apertures, the computer for receiving the electronic image data from each of the plurality of apertures, the computer performs a spatial frequency analysis of the electronic image data and sends, to a display device, the processed image data for the near region and the far region from one of the first aperture, the second aperture, and the third aperture having a high spatial frequency; and
the display device being disposed on said mounting structure and communicatively coupled with said computer for receiving the processed image data having the high spatial frequency, the display device further having a visual display for rendering the scene, wherein both the near region and the far region are in focus in the rendered scene.

Abstract
The present invention is directed to an electronic vision system. The system implements at least 3 apertures. A first aperture is set at near focus, while second and third apertures (positioned to the left and right of the first aperture respectively) are set at far focus. The fields of view of the left and right apertures may be spaced apart relative to each other, thereby forming a blind spot in the overall field of view of the system. However, the field of vision of the center aperture overlaps the blind spot, thereby reducing the blind spot for the system. The system includes a computer configured for receiving electronic image data from the apertures and rendering display data derived from the received image data. The system includes a display mounted to a mounting structure (ex.—helmet) for receiving the display data and displaying visual images of the display data.
