Abstract
A camera system is provided having an integral sound recording means for recording and outputting a permanent record of sound associated with a photograph wherein the sound is recorded with infrared ink. Also provided are means for reproducing the recorded sound and a photograph reader to decode sound and to play sound. Further provided is a method of decoding a pre-recorded audio signal printed as an array of invisible ink dots on the surface of a photograph coincident with an image printed on the surface of the photograph.
Claims12
A handheld camera comprising:
- a housing;
- an image sensor contained in the housing for generating image data representing a sensed image;
- an audio sensor contained in the housing for generating audio data representing the sensed audio signal;
- a processor contained in the housing for generating coded data using at least some of the audio data, said coded data encoding the audio data;
- and
- a pagewidth inkjet printhead contained in the housing, said printhead being configured for printing the image onto a face of a substrate using the image data and at the same time printing the coded data onto the same face of the substrate in substantially the same area as the image,
- wherein the coded data is printed as an array of substantially invisible dots using infrared (IR) absorbing ink.
A method of printing from a handheld camera comprising the steps of:
- sensing an image using an image sensor contained in a camera housing and generating image data representing the sensed image;
- sensing an audio signal using an audio sensor contained in the housing and generating audio data representing the sensed audio signal;
- generating coded data from at least some of the audio data, said coded data encoding the audio data;
- and
- printing the image onto a face of a substrate using a pagewidth printhead contained in the housing, wherein said printing prints the image from the image data and at the same time prints the coded data onto the same face of the substrate in substantially the same area as the image,
- wherein the coded data is printed as an array of substantially invisible dots using infrared (IR) absorbing ink.
