Abstract
A camera field indicating method, system, and non-transitory computer readable medium for a camera including imaging optics, a light sensor, the imaging optics and the light sensor intermittently sensing incoming light, and an edge-lit illuminator including a light source and a leaky waveguide situated adjacent the imaging chip so as to share the imaging optics with the light sensor.
Claims6
A camera comprising:
- imaging optics;
- a light sensor, the imaging optics and the light sensor intermittently sensing incoming light;
- and
- an edge-lit illuminator comprising a light source and a leaky waveguide situated adjacent the imaging chip so as to share the imaging optics with the light sensor.
A camera field indicating method for a camera including a light sensor, imaging optics, and an edge-lit illuminator including a light source and a leaky waveguide situated adjacent the imaging chip so as to share the imaging optics with the light sensor, the method comprising:
- intermittently activating the edge-lit illuminator when the light sensor does not need to sense incoming light such that a projection of the light source and the leaky waveguide through the imaging optics matches a field of view of the light source.
A camera field indicating system for a camera including a light sensor, imaging optics, and an edge-lit illuminator including a light source and a leaky waveguide situated adjacent the imaging chip so as to share the imaging optics with the light sensor, said system comprising:
- a processor;
- and
- a memory, the memory storing instructions to cause the processor to perform:
- intermittently activating the edge-lit illuminator when the light sensor does not need to sense incoming light such that a projection of the light source and the leaky waveguide through the imaging optics matches a field of view of the light source.
