Abstract

A camera that includes negative film and a CCD sensor for simultaneously capturing images chemically and electronically using a beam splitter. A liquid crystal display is used for viewing the captured images immediately after they are captured or for reviewing images stored in a removable memory for deletion or output. An adjustable lens and mirror which can route light from the source directly to the film when a high quality image is to be captured, so that the source light is not split between the film negative and the sensor. The images can be stored at various densities, such as 3×5 print or fax resolution, to match the intended output. The memory is organized into stack locations. Each stack location can store one or more images of varying densities allowing the camera to effectively use the memory. The storage status of each stack location is indicated by stack location partition flags. A full memory can also be removed and replaced. The stored images can also be transferred to other forms of media.

Claims

1. A camera for capturing images of different quality levels, said camera comprising:

a lens section providing a common source for generating a source image;

a beam splitter for splitting the source image into a first image and a second image; and

capture means for providing two quality levels of film capture and a further level of electronic capture for the source image from the common source, said capture means including;

a film optically coupled to said beam splitter so as to capture only the first image;

an electronic sensor optically coupled to said beam splitter for capturing the second image;

a light routing mechanism for optically decoupling the film from the beam splitter and routing the source image to said film and capturing a third image while bypassing said beam splitter; and

a user interface for selecting one of two levels of image storage quality for film capture, said two levels including a first level for obtaining a lower quality of film capture from the first image when the film is optically coupled to said beam splitter and a second level for obtaining an improved quality o film capture from the third image by optimum utilization of the source image when the light routing mechanism optically decouples the film from said beam splitter.

2. A camera as recited in claim 1, wherein said routing mechanism comprises an adjustable lens and a mirror coupled between the common source and the film for bypassing the splitter.

3. A camera as recited in claim 1, wherein said routing mechanism comprises means for pivoting said splitter out o a light path between the common source and said film.

4. A method for capturing images of different quality levels, said method comprising the steps of:

focusing a source image from a common source;

optically splitting the source image into a first image and a second image by means of a beam splitter;

optically coupling a film to said first image so as to capture only the first image;

optically coupling an electronic sensor to said second image for capturing the second image;

optically decoupling the film from the beams splitter and routing the source image to said film and capturing a third image while bypassing said optical splitting step; and

selecting one of two levels of image storage quality of film capture for the source image from the common source, said two levels including a first level for obtaining a lower quality of film capture from the first image when the film is optically coupled to the beam splitter and a second level for obtaining an improved quality of film capture from the third image by optimum utilization of the source image when the film is optically decoupled from the beam splitter and the source image is routed to the film.
