Blur display for automotive night vision systems with enhanced form perception from low-resolution camera images
First Claim
Patent Images
1. A night vision imaging system for a vehicle, comprising:
- a) a low resolution infrared sensor camera for perceiving an object and producing a pixilated low resolution image block with edges in response;
b) a signal processor adapted for receiving said image signal and processing the image signal into a display signal; and
c) spatial filter adapted to blur out high spatial frequencies provided by said block edges of said low resolution image block to produce a visual image; and
d) a human interface visual display to view the visual image.
