## Abstract

A method and an apparatus for archiving an image on a photographic medium are described. The image consists of an array of pixels, where a color depth of the pixels is n bits. In addition to recording the array of pixels on the photographic medium also a subset of the n bits describing the color of the pixel is recorded on the photographic medium for each pixel.

## Claims

### Claim 1

A method for archiving an image on a photographic medium, the image consisting of an array of pixels, where a color depth of the pixels is n bits, n being an integer, the method comprising the steps of:
recording the array of pixels of the image on the photographic medium; and
additionally recording for each pixel of the array of pixels a subset of the n bits describing the color of the pixel on the photographic medium.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the subset of the n bits includes bits that are most affected by a degradation of the photographic medium or by insufficiencies of a process for retrieving the image from the photographic medium.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the subset of the n bits includes the least significant bits.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising the step of generating the image by digitizing an analog image.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the subset of the n bits is recorded as a checkered pattern of binary values or grey values.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the checkered pattern comprises error correction data.

### Claim 7 (depends on 5)

The method according to claim 5, wherein the checkered pattern is divided into two or more blocks associated to sets of adjacent pixels of the image.

### Claim 8 (depends on 7)

The method according to claim 7, wherein the two or more blocks are provided with position information of the associated sets of adjacent pixels of the image.

### Claim 9 (depends on 1)

The method according to claim 1, wherein the image and the subset of the n bits are recorded in neighboring areas of the photographic medium, on separate areas of the photographic medium, or on separate photographic media.

### Claim 10 (depends on 1)

The method according to claim 1, wherein recording of the image and the subset of the n bits is performed by printing.

### Claim 11 (depends on 1)

The method according to claim 1, wherein the photographic medium is a film, a microfilm, or a microfiche.

### Claim 12

An apparatus for archiving an image on a photographic medium, the image consisting of pixels, where a color depth of the pixels is n bits, n being an integer, the apparatus comprising:
a processor for determining for each pixel of the array of pixels a subset of the n bits describing the color of the pixel; and
a recorder for recording the array of pixels of the image and additionally for each pixel of the array of pixels the determined subset of the n bits on the photographic medium.
