1. An imaging device for adding auxiliary information to digital data, said imaging device comprising:
- an interface device operable to receive an externally generated image inputan information button operable to input auxiliary information indicating a degree of importance of digital data, according to user operation;
an imaging unit operable to capture and photoelectrically convert an image into an image signal when said interface device receives the externally generated image input;
a coding device operable to generate first digital data by compressing the image signal created by said imaging unit when said interface device receives the externally generated image input;
a selection unit operable to select an instruction of how to record the auxiliary information for (i) an important scene, (ii) a change of shooting location, and (iii) a predetermined time; and
a digital data generation device operable to combine, at a time when the auxiliary information is input and the image is captured and photoelectrically converted into the image signal by said imaging unit, the auxiliary information received at the time with the first digital data corresponding to the image captured and photoelectrically converted by said imaging unit at the time, according to the instruction selected by the selection unit, to produce second digital data comprising the combined auxiliary information and first digital data, and output the second digital data to a recording device or a transmission device.

Abstract
Auxiliary information relating to digital data such as video and audio data is generated in synchronization with power-on, or generated according to an instruction from the user operating an information button or the like. Further, only an important portion of digital data is extracted by using the auxiliary information to generate reduced digital data, whereby the time and cost required for transmission is reduced.

8. An imaging method for adding auxiliary information to digital data, said imaging method comprising:
-
receiving an externally generated image input; receiving an auxiliary information input indicating a degree of importance of digital data, via an information button according to user operation; capturing and photoelectrically converting an image into an image signal upon said receiving of the externally generated image input; generating first digital data by compressing the image signal created by said capturing and photoelectrically converting of the image upon said receiving of the externally generated image input; selecting an instruction of how to record the auxiliary information for (i) an important scene, (ii) a change of shooting location, and (iii) a predetermined time; combining, at a time of said receiving of the auxiliary information and of said capturing and photoelectrically converting the image into the image signal, the auxiliary information received at the time with the first digital data corresponding to the image captured and photoelectrically converted, at the time, by said capturing and photoelectrically converting, according to the selected instruction, to produce second digital data comprising the combined auxiliary information and first digital data; and outputting the second digital data to a recording device or a transmission device.
