ABSTRACT:

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.
FIELD OF THE INVENTION
The present invention relates to the field of digital image processing and, in particular, discloses a method of producing a Photo Negative of a particular captured image for later. Using an ink jet printing system.
BACKGROUND OF THE INVENTION
The present invention relates to a camera system recently proposed for the printing out of images. The camera system is more fully set out in Australian provisional patent specification PO7991 entitled “Image Processing Method and Apparatus (Art 01)”. In addition to Australian provisional patent specification PO8505 entitled “Image Processing Method and Apparatus (Art 01 a)” both of which were filed by the present applicant in addition to a number of associated provisional specifications mentioned therein. The contents of these applications are hereby incorporated by cross-reference.
The aforementioned specifications disclose a camera system provided for the immediate print out of sensed images utilising an internal ink jet pagewidth printhead and print roll. Also disclosed in the aforementioned specifications is the utilisation of an “Artcard” card for insertion into the camera so as to provide for various manipulation effects by the camera device.
Traditionally silver halide camera processing systems have given rise to the well known utilisation of a “negative” for the production of multiple prints. The negative normally forms the source of the production prints and the practice has grown up for the independent care and protection of negatives for their subsequent continual utilisation.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide for the provision of digital “negatives” which can be utilised to provide a highly resilient and convenient form of storage of data such as a sensed photograph or manipulated digital image using an ink jet printing system.
In accordance with a first aspect of the present invention, there is provided a method of creating a permanent digital copy of an image captured on an image sensor of a handheld camera device having an interconnected integral computer device and an integral pagewidth ink jet printer means for printing out on print media stored with the camera device, the method comprising the steps of sensing an image with the image sensor; converting the image to an encoded form of the image, the encoded form having fault tolerant encoding properties; printing out the encoding form of the image as a permanent digital record of the image utilizing the integral pagewidth ink jet printer means.
Preferably, the integral pagewidth ink jet printer means includes means for ink jet printing on a first and second surface of the print media and the sensed image or a visual manipulation thereof is printed on the first surface thereof and the encoded form is printed on the second surface thereof. A reduced size (thumbnail) of the sensed image can be printed alongside the encoded form of the image and the fault tolerant encoding can include forming a Reed-Solomon encoded version of the image in addition to applying a high frequency modulation signal such as a checkerboard pattern to the encoded form such that the permanent record includes repeatable high frequency spectral components. The print media can be supplied in a print roll means which is detachable from the camera device.
