Abstract
An information signal processing apparatus according to the present invention is arranged to receive, as an input, an information signal to temporarily store therein the input information signal and to temporarily store therein management information prepared during a recording of the information signal in the recording medium, thereby recording the temporarily stored information signal and management information in the recording medium. Accordingly, it is possible to record an information signal having a large amount of information in the recording medium without lowering a recording speed and it is also possible to easily reduce the size, weight and cost of the apparatus.
Claims20
A camera comprising:
- an image sensor for converting an object image into an analog image signal:
- an A/D converter for converting said analog image signal into a digital image signal;
- a compression circuit for compressing said digital image signal in a predetermined compression method to produce compressed image data;
- a file generator for generating an image data file based on said compressed image data;
- a counter for counting numerical value when generating each image file, wherein said counter hold said numerical value even if the power of the camera is off;
- a file name generator for generating each file name using the numerical value counted by said counter and a discrimination number generated from a number specific to the camera;
- and
- a recording circuit for recording said image data file on a recording medium.
