Abstract

A recording apparatus of the kind recording a moving image signal in a first area on a recording medium and a still image signal in a second area on the recording medium is arranged to selectively display the moving image signal or the still image signal, and to display, along with the image on display, information which indicates that the still image is in the process of being recorded. The arrangement enables the operator of the apparatus to know that the apparatus is in the process of recording the still image as well as the contents of the still image being recorded and thus enables the operator to avoid faulty recording, etc.

Claims

1. A video signal recording apparatus, comprising:

a) recording means arranged to record a moving image signal and a digital still image signal on a recording medium with a recording period of said digital still image signal being longer than a period of one picture of a moving image, thus enabling instruction of recording of a still image during the recording of said moving image signal; and

b) display means for selectively displaying the moving image corresponding to the moving image signal and the still image corresponding to the digital still image signal, wherein said display means changes from displaying the moving image to displaying the still image corresponding to the digital still image signal in response to a start of recording of the digital still image signal by said recording means, and wherein said display means automatically changes from displaying the still image to displaying the moving image after a predetermined period of time has elapsed since the digital still image signal started to be recorded.

2. A recording apparatus, comprising:

a) a memory for storing an image signal for one picture of a moving image signal obtained by an image sensor;

b) still image signal generating means for repeatedly reading the image signal for one picture from the memory and thereby generating a digital still image signal;

c) recording means for recording the moving image signal and the digital still image signal on a recording medium with a recording period of said digital still image signal being longer than a period of one picture of a moving image, thus enabling instruction of recording of a still image during the recording of said moving image signal;

d) display means for displaying the moving image represented by the moving image signal and the still image represented by the digital still image signal; and

e) a controller for controlling said display means so as to change from displaying the moving image to displaying the still image represented by the digital still image signal in response to a start of recording of the digital still image signal by said recording means, to automatically change from displaying the still image to displaying the moving image after a predetermined period of time has elapsed since the digital still image signal started to be recorded.

3. An apparatus according to claim 2, wherein the still image is a digital signal.

4. An apparatus according to claim 2, wherein the still image signal generating means includes reading means for repeatedly reading the image signal for one picture from the memory, compressing means for compressing an information amount of the still image signal, and PCM processing means for adding an error correction code and ID code to the still image signal.

5. An apparatus according to claim 4, wherein the compressing means compresses the information amount of the still image signal with a plurality of compression ratios which are different from each other.

6. An apparatus according to claim 2, wherein the recording means has a rotary head for tracing the recording medium to form a plurality of tracks, each of the moving image signal and the still image signal being recorded on said plurality of tracks.

7. A recording apparatus arranged to generate a moving image signal by an image sensor and generate a digital still image signal by using the moving image signal to form a plurality of tracks on a tape-shaped recording medium and record the moving image signal and the digital still image signal on the plurality of tracks, and to selectively display by an electronic viewfinder a moving image represented by the moving image signal and a still image represented by the digital still image signal with a recording period of said digital still image signal being longer than a period of one picture of the moving image, thus enabling instruction of recording the still image during the recording of said moving image signal, wherein said electronic viewfinder changes from displaying the moving image to displaying the still image represented by the digital still image signal in response to a start of recording of the digital still image signal by recording means, to automatically change from displaying the still image to displaying the moving image after a predetermined period of time has elapsed since the digital still image signal started to be recorded.

8. A recording apparatus, comprising:

imaging means for receiving an object light and generating a moving image signal representing the object;

still image signal generating means for generating a digital still image signal by using the moving image signal obtained by said imaging means;

recording means for recording the moving image signal and the digital still image signal on a recording medium with a recording period of said digital still image signal being longer than a period of one picture of a moving image;

a manually operable member for manually instructing a recording of the digital still image signal by said recording means thus enabling instruction of recording of a still image during the recording of said moving image signal;

display means for displaying the moving image represented by the moving image signal and the still image represented by the digital still image signal; and

controlling means for controlling said display means so as to change from displaying the moving image to displaying the still image represented by the digital still image signal in response to an instruction of said manually operable member, to automatically change from displaying of the still image to displaying of the moving image after a predetermined period of time has elapsed since the digital still image signal started to be recorded.

9. An apparatus according to claim 8, wherein said still image signal generating means comprises a memory for storing an image signal for one picture of the moving image signal obtained by said imaging means, said still image signal generating means reading the image signals for one picture from said memory and thereby generating the digital still image signal.

10. An apparatus according to claim 9, wherein said still image signal generating means includes compressing means for compressing an information amount of the digital still image signal.

11. An apparatus according to claim 9, wherein said still image signal generating means includes error correction coding means for adding an error correction check code to the digital still image signal.

12. An apparatus according to claim 8, wherein said recording means forms a plurality of tracks on a tape-shaped recording medium and records the digital still image signal on the plurality of tracks formed on the tape-shaped recording medium.
