a first imager part configured for generating image data from the interior portion; and
a second imager part configured for generating image data from the exterior portion.
4. The apparatus according to claim 1 , wherein the field of view is 120 degrees or more.
5. The apparatus according to claim 1 , further comprising:
a mount for mounting the apparatus such that the field of view includes the interior portion and the exterior portion.
6. A system comprising:
a vehicle camera configured to be mounted within a vehicle such that a field of view of the vehicle camera includes an interior portion representing part of an interior of the vehicle and an exterior portion representing part of an exterior of the vehicle, the vehicle camera comprising:
an imager comprising a plurality of pixels configured for generating image data of the interior portion and exterior portion, and including an excluded region for not generating image data of an excluded portion between the interior portion and exterior portion; and
an ultra-wide-angle lens assembly configured for focusing onto the imager an ultra-wide-angle image having the field of view, the ultra-wide-angle lens assembly comprising a first focal region having a first set of optical characteristics for focusing the interior portion of the field of view onto the imager on a first side of the excluded region, and a second focal region having a second set of optical characteristics for focusing the exterior portion of the field of view onto the imager on a second side of the excluded region; and
an image processor configured for processing the ultra-wide-angle images formed on the imager, the image processor comprising:
an image splitter block for separating the interior and exterior portions of the ultra-wide-angle image.
7. The system according to claim 6 , wherein the image processor further comprises:
an interior processing part configured for processing the interior portion of the ultra-wide-angle image and outputting a corrected interior image feed for use in one or more interior sensing functions; and
an exterior processing part configured for processing the exterior portion of the ultra-wide-angle image and outputting a corrected exterior image feed for use in one or more exterior sensing functions.
8. The system according to claim 6 , wherein the image processor further comprises:
at least one de-warping block configured for processing at least a portion of the ultra-wide-angle image to correct image distortions.
9. A system according to claim 8 , wherein the image processor further comprises:
an interior processing part configured for processing the interior portion of the ultra-wide-angle image and outputting a corrected interior image feed configured for use in one or more interior sensing functions; and
an exterior processing part configured for processing the exterior portion of the ultra-wide-angle image and outputting a corrected exterior image feed configured for use in one or more exterior sensing functions.
10. The system according to claim 9 , wherein the image processor further comprises:
an interior de-warping block configured for processing the interior portion of the ultra-wide-angle image to correct image distortions; and
an exterior de-warping block configured for processing the exterior portion of the ultra-wide-angle image to correct image distortions.
11. The system according to claim 8 , wherein the image processor further comprises:
an interior de-warping block configured for processing the interior portion of the ultra-wide-angle image to correct image distortions; and
an exterior de-warping block configured for processing the exterior portion of the ultra-wide-angle image to correct image distortions.
12. The system according to claim 11 , wherein the image processor further comprises:
an interior processing part configured for processing the interior portion of the ultra-wide-angle image and outputting a corrected interior image feed for use in one or more interior sensing functions; and
an exterior processing part configured for processing the exterior portion of the ultra-wide-angle image and outputting a corrected exterior image feed for use in one or more exterior sensing functions.
13. The system according to claim 6 , further comprising:
the vehicle.
14. A method comprising:
receiving image data from an imager of ultra-wide-angle images having a field of view that includes an interior portion representing part of an interior of a vehicle and an exterior portion representing part of an exterior of the vehicle and not receiving image data of an excluded portion between the interior portion and exterior portion; and
processing the image data by separating the interior and exterior portions of each ultra-wide-angle image using an image splitter block;
wherein a first focal region of a lens assembly associated with the imager has a first set of optical characteristics for focusing the interior portion of the field of view onto the imager on a first side of the excluded portion, and a second focal region having a second set of optical characteristics for focusing the exterior portion of the field of view onto the imager on a second side of the excluded portion.
