Abstract

PROBLEM TO BE SOLVED: To inexpensively record and reproduce a data file of a PC card by reproducing the dubbing picture or sound on a TV monitor with a means for reading the data file of the picture or sound which are recorded on the PC card, and a means converting the format for dubbing to a DVD-RAM. SOLUTION: When the command for dubbing from the PC card to the DVD- RAM is issued from a switch group 3, the data file of the picture or sound is read out from the PC card by a PC card controller 1. Relating to a format converter 12, the read out data file is converted to the format recognizable by a DVD-RAM controller 2 and outputted, then the receiving data are written into the DVD-RAM by the DVD-RAM controller 2. When the command for taking out the picture file from the DVD-RAM and reproducing it to the TV monitor is issued by the switch group 3, the data file of the DVD-RAM picture or the sound is read out by the DVD-RAM controller 2, then decoded to an AV signal and outputted after the required format conversion is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for reading and writing data from and to a nonvolatile storage medium.

[0002]

2. Description of the Related Art In recent years, cameras that compress and record images and sounds on a PC (Personal Computer) card have appeared. For example, it is a digital still camera, and is an MPEG camera (for example, described in the March 1997 issue of the Visual Media Society of Japan, page 337).

[0003] In this MPEG camera, a moving image and a voice photographed by the camera are converted into a digital signal, and then the MPEG (Mov)
ing Pictures Expert Group)
It can be recorded as a data file on the card.
In a digital still camera or an MPEG camera, a still image (still image) is photographed by a camera, and the digital image is converted into a digital image, and then converted to a JPEG (Joint Photographic Expert Group).
It can be compressed according to the standard and recorded as a data file on a PC card.

[0004]

However, this PC card is suitable as a recording medium for a camera because it is small in size and can withstand a certain amount of vibration, but has the disadvantage that it has a small storage capacity and is expensive. is there. For example,
Digital still cameras often use flash memory type PC cards as storage media, but have a storage capacity of 10 MB.
Only about 100 still images can be recorded on a (megabyte) PC card, and the flash memory type 10 MB PC card is quite expensive.

[0005] In the MPEG camera, a hard disk type PC card is used as a storage medium.
A moving picture can be recorded on a 60MB (megabyte) PC card for about 20 minutes.
C cards are also quite expensive. Therefore, a large number of PC cards are required to photograph and retain many moving images and still images, which requires considerable cost.

In order to avoid this problem, it is necessary to copy moving image and still image data files recorded on a PC card to another inexpensive recording medium having a large storage capacity. DVD-RAM (Digital Video Disc-Random) is the most advanced inexpensive storage medium with large storage capacity.
Access Memory). DVD-RAM has a diameter of 12
cm (centimeter), which is somewhat weaker than a PC card, but has a huge storage capacity of 2.6 GB (gigabyte) on one side, but can record on both sides (described in Nikkei Electronics May 5, 1997, p. 13). However, it is significantly cheaper than a PC card. However, it is important not only to be able to copy the image and audio data files recorded on the PC card to the DVD-RAM, but also to have a function of reproducing them on a television monitor or the like.

An object of the present invention is to provide a digital still camera,
Provided is a recording apparatus that can easily dub image and audio data files recorded on a PC card by photographing with an MPEG camera or the like to an inexpensive DVD-RAM and reproduce the copied images and audio on a television monitor or the like. To do.

[0008]

In order to achieve the above object, the present invention provides a means for reading an image or audio data file recorded on a PC card, and a method for reading and writing the read data file on a DVD-RAM. It comprises a means for converting the data file into a format that can be converted, a means for dubbing the converted data file to a DVD-RAM, and a means for reproducing the dubbed image or sound on a television monitor.
