Abstract
A method and apparatus for capturing an image of at least one object appearing in a field of view (FOV). A housing has an image sensor and a base lens assembly fixedly mounted relative thereto. A moveable lens assembly is movably mounted relative to the housing. The moveable lens, the base lens assembly, and the image sensor are aligned such that light received within the FOV passes through the moveable lens and the base lens assembly and impinges onto the image sensor. The light received from the FOV forms an original image prior to entering the movable lens and the base assembly. Light from the FOV impinging onto the sensor forms an impinging image.
Claims22
An imaging assembly for capturing an image of at least one object appearing in a field of view (FOV), the imaging assembly comprising:
- a housing;
- an image sensor fixedly mounted relative to the housing;
- a base lens assembly fixedly mounted relative to the housing;
- and
- a moveable lens movably mounted relative to the housing,
- wherein:
- the moveable lens, the base lens assembly, and the image sensor are aligned such that light received within the FOV (i) passes through the moveable lens and the base lens assembly, and (ii) impinges onto the image sensor;
- prior to entering any one of the moveable lens and the base lens assembly, the light received from the FOV forms an original image;
- the light received from the FOV that impinges onto the image sensor forms an impinging image;
- and
- at least one of the moveable lens and the base lens assembly is operable to simultaneously magnify at a first magnification value and magnify at a second magnification value such that a first part of the impinging image is magnified at the first magnification value relative to the original image and a second part of the impinging image is magnified at the second magnification value relative to the original image.
An imaging scanner for capturing an image of at least one object appearing in a field of view (FOV), the imaging scanner comprising:
- a housing;
- an image sensor fixedly mounted relative to the housing;
- a base lens assembly fixedly mounted relative to the housing;
- and
- a moveable lens movably mounted relative to the housing,
- wherein:
- the moveable lens, the base lens assembly, and the image sensor are aligned such that light received from the FOV (i) passes through the moveable lens and the base lens assembly, and (ii) impinges onto the image sensor;
- prior to entering any one of the moveable lens and the base lens assembly, the light received within the FOV forms an original image;
- the light received from the FOV that impinges onto the image sensor forms an impinging image;
- and
- the base lens assembly includes a first base lens having a first side that is at least partially concave and a second side that is at least partially both concave and convex.
A method of capturing an image of at least one object appearing in a field of view (FOV) of an imaging device, the method comprising:
- providing a housing;
- fixedly mounting an image sensor relative to the housing;
- fixedly mounting a base lens assembly relative to the housing;
- movably mounting a moveable lens relative to the housing;
- aligning the moveable lens, the base lens assembly, and the image sensor such that light received within the FOV (i) passes through the moveable lens and the base lens assembly, and (ii) impinges onto the image sensor;
- prior to entering any one of the moveable lens and the base lens assembly, forming an original image with the light received from the FOV;
- forming an impinging image with the light impinging onto the image sensor;
- and
- simultaneously magnifying the original image via at least one of the moveable lens and the base lens assembly at a first magnification value and a second magnification value such that a first part of the impinging image is magnified at the first magnification value relative to the original image and a second part of the impinging image is magnified at the second magnification value relative to the original image.
