Imaging apparatus with divers resolution

Abstract

An imaging apparatus with divers resolution includes a light source, a reflection lens set, a major lens and an image-capture unit. The light source is used to illuminate a document for further generating a document image. The reflection lens set includes a plurality of reflection lenses for forwarding the document image consecutively to the major lens. The major lens is used to receive the document image transported by the reflection lens set and to form the document image at a focal point thereof. The image-capture unit includes a plurality of image-capture elements with various resolution for meeting divers usage requirements. While in usage, a suitable image-capture element with particular resolution can be shifted to the focal point of the major lens for performing the imaging.

       5. The imaging apparatus with divers resolution according to  claim 1 , includes  further comprising at least one reflection lens arranged to obtained an optical path for forwarding said document image. 
     
     
       6. The imaging apparatus with divers resolution according to  claim 1 , wherein said image-capture unit is moved manually to locate said selected image-capture element. 
     
     
       7. The imaging apparatus with divers resolution according to  claim 1 , wherein said image-capture unit is moved electronically to locate said selected image-capture element. 
     
     
       8. The imaging apparatus with divers resolution, comprising:
 a light source for illuminating a document to form a respective document image;  
 a major lens for receiving the document image and for imaging the document imaging  image at a focal point thereof; and  
 an image-capture unit, located at the focal point of the major lens, including a plurality of image-capture elements with respectively various resolution for forming thereon the document image;  
 characterized on that: the image-capture unit further includes a switching device for determining one of the image-capture elements per a user's need as a selected image-capture element for performing document imaging.  
 
     
     
       9. The image apparatus with divers resolution according to  claim 8 , wherein said imaging-capture  image- capture  element of said imaging-capture  image- capture  unit is a charge coupling device. 
     
     
       10. The imaging apparatus with divers resolution according to  claim 8 , includes  further comprising at least one reflection lens arranged to obtained an optical path for forwarding said document image. 
     
     
       11. The imaging apparatus with divers resolution according to  claim 8 , wherein said switching device of said image-capture unit is an electronic device for locating said selected image-capture element. 
     
     
       12. The imaging apparatus with divers resolution according to  claim 8 , wherein said image-capture elements of said image-capture unit are arranged close to said focal point of said major lens. 
     
     
       13. The imaging apparatus with divers resolution according to  claim 8 , wherein said switching device includes operations of:
 (a) selecting one of said image-capture element as said selected image-capture element;  
 (b) using an electronic controller to activate said selected image-capture element and to invalidate the rest of said image-capture elements; and  
 (c) imaging said document image via said selected image-capture element.  
 
     
     
       14. An apparatus comprising:
   an image - capture unit, including a plurality of image - capture elements having respective resolutions, wherein the image - capture unit is operable to select at least one of the image - capture elements at least in part by moving the selected image - capture element to a focal point of a lens.     
     
     
       15. A method comprising:
   selecting one of a plurality of image - capture elements based at least in part on a respective resolution of the selected image - capture element; and        positioning said selected image - capture element at a focal point of a lens, at least in part, by moving an image - capture unit, said image - capture unit including said plurality of image - capture elements.
