Camera with printhead for printing images with encoded audio data
View Patent ↗A handheld camera comprises a housing containing an image sensor for generating image data; an audio sensor for generating audio data; a processor for generating coded data using the audio data and a pagewidth inkjet printhead. The printhead is 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 the same area as the image.
1. 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 sensed audio;
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.
2. A camera according to claim 1 , further comprising a supply of inks for printing the image and the coded data.
3. A camera according to claim 1 , wherein the supply of inks comprises an infrared-absorbing ink for printing the coded data.
4. A camera according to claim 1 , wherein the coded data is printed as a dot pattern in substantially the same area as the image.
5. A camera according to claim 1 , wherein said coded data further encodes the image data.
6. A camera according to claim 1 , wherein the image sensor comprises a CDD image sensor.
7. A camera according to claim 1 , wherein the audio sensor comprises a microphone.
8. A camera according to claim 6 , wherein the microphone is coupled to a sound processor for digitizing an analogue signal generated by the microphone to thereby generate the audio data.
9. A camera according to claim 1 further comprising a memory for temporarily storing at least one of the image data and the audio data prior to printing the image.
10. 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 audio 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 using 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.
11. A method according to claim 10 , further comprising the step of:
storing at least one of the image data and the audio data prior to printing the image.
12. A method according to claim 10 , wherein said coded data further encodes the image data.
