The system includes a camera having a sensing system for sensing an image and recording an audio signal and a processor for generating coded data at least partially indicative of the audio signal and causing the photograph to be printed by printing the image and the coded data. The coded data is printed in substantially the same area of the photograph as the image. The system also includes a reader having a scanner for scanning the coded data, a processor for decoding the coded data to determine the audio signal and an output for playback of the audio signal. ## Claims ### Claim 1 A system for recoding and playing an audio signal provided on a photograph, the system including: a camera comprising i) a sensing system for sensing an image and recording an audio signal; and ii) a processor for generating coded data at least partially indicative of the audio signal, and for controlling a printing device to print a photograph including the image and the coded data; and a reader comprising i) a scanner for scanning the coded data; ii) a processor for decoding the coded data to determine the audio signal; and iii) an output for playback of the audio signal, wherein the processor causes the coded data to be printed in the same area as the image, the coded data includes a beginning target boundary printed at a start of the coded data in a feed direction of the photograph through the reader, and an end target boundary printed at an end of the coded data in the feed direction, the beginning and end target boundaries delimiting the spatial location of the coded data therebetween in the feed direction, and the processor controls the printing device to print the beginning and end target boundaries spatially displaced from the rest of the coded data in the feed direction. ### Claim 2 (depends on 1) A system according to claim 1, wherein the sensing system includes a CDD image sensor. ### Claim 3 (depends on 1) A system according to claim 1, wherein the sensing system includes a microphone coupled to a sound processor for digitising an analogue audio signal generated by the microphone to thereby generate a digital audio signal. ### Claim 4 (depends on 1) A system according to claim 1, wherein the processor is coupled to a memory for temporarily storing at least one of image data and the audio signal prior to printing the photograph. ### Claim 5 (depends on 1) A system according to claim 1, wherein the camera includes a printer for printing the photograph. ### Claim 6 (depends on 1) A system according to claim 1, wherein the coded data is printed using infra-red responsive ink and the scanner is an infra-red scanner. ### Claim 7 (depends on 1) A system according to claim 1, wherein the reader includes an arm having a slot through which said card is inserted. ### Claim 8 (depends on 7) A system according to claim 7, wherein the scanner is located in the arm. ### Claim 9 (depends on 7) A system according to claim 7, wherein the arm includes pinch rollers positioned at either end of the slot, the pinch rollers being adapted to align photographs with the scanner. ### Claim 10 (depends on 1) A system according to claim 1, wherein the coded data is adapted to be scanned by a scanner extending in a scan direction as the photograph moves passed the sensor in a feed direction, the feed direction and the scan direction being substantially orthogonal. ### Claim 11 (depends on 1) A system according to claim 1, wherein the coded data is printed as an array of substantially invisible dots. ### Claim 12 (depends on 1) A system according to claim 1, wherein the coded data is redundantly encoded using Reed-Solomon encoding. ### Claim 13 (depends on 1) A system according to claim 1, wherein the coded data is encoded using a high frequency checkerboard modulation of an array of ink dots. ### Claim 14 (depends on 1) A system according to claim 1, wherein the photograph includes information including at least one of: photograph location; photograph date; and, photograph time.
