Abstract

Disclosed is a portable magnifier camera that can be selectively positioned into a variety of configurations. At least four distinct viewing configurations are provided: a reading mode wherein the camera rests flatly upon the viewed object; a writing mode wherein the camera rests at an angle upon the viewed object; a hand-held mode wherein the user holds the camera relative to a distant object; and an inspection mode wherein the user holds the viewed object relative to the camera. These configurations enable a user to effectively view objects of differing size and at varying distances.

Claims

1. A lighting system for a portable camera, the camera functioning to magnify an object residing in an image plane, the lighting system comprising:

an optical chamber adapted to be positioned over the image plane, the optical chamber having a lightly colored internal surface for promoting light reflection, the internal surface including a curved wall, an angled wall and two side walls therebetween, a mirror positioned upon the angled wall for reflecting the image of the object residing in the image plane;

a CMOS image sensor positioned within the optical chamber opposite the mirror so as to record the image reflected by the mirror, the output of the image sensor being provided to an output screen by way of a field programmable gate array;

a row of light emitting diodes positioned upon each of the side walls of the optical chamber, a light guide with upper and lower surfaces positioned over each row of light emitting diodes, the lower surface being parallel to the image plane and the upper surface being angled with respect to the image plane, the light guides functioning to help control the amount of direct and indirect lighting received by the object, whereby the light guides causes more indirect lighting when the image plane is in close proximity to the optical chamber and more direct lighting when the image plane is further away from the optical chamber.

2. A lighting system for a portable camera, the lighting functioning to magnify an object residing in an image plane, the system comprising:

an optical chamber including a curved wall, an angled wall and two side walls therebetween, the optical chamber including a lightly colored interior;

an image sensor positioned within the optical chamber, the output of the image sensor being provided to an output screen;

a row of LEDs positioned upon each of the side walls, each row of LEDs contained within a light guide, each light guide having a first slanted surface and a second surface that is parallel to the image plane, the first and second surfaces being operatively related to the LEDs, the light guide functioning to help control the amount of direct and indirect lighting received by an object being magnified.

3. The lighting system as described in claim 2 wherein the lightly colored interior of the light chamber promotes light reflection.

4. The lighting system as described in claim 2 wherein a mirror is positioned within the optical chamber for reflecting the image of the object being magnified.

5. The lighting system as described in claim 2 wherein the light guide causes more indirect lighting when the object being magnified is in close proximity to the optical chamber and more direct lighting when the object being magnified is further away from the optical chamber.

6. The lighting system as described in claim 2 wherein the image sensor is a CMOS image sensor.

7. The lighting system as described in claim 2 wherein the output of the image sensor is provided to the output screen by way of a field programmable gate array.
