Abstract

A recording apparatus for recording an information signal on a recording medium is arranged to be controlled according to control information read out from an external storage device which is attachable and detachable to and from the recording apparatus, so that the apparatus is not only simply operable but also has diverse functions. One of the features of the apparatus lies in that the timing of start or stop of recording can be synchronized with that of a signal combining action or a signal fade-in or fade-out action.

(a) input means for inputting a first video signal;

(b) a storing portion for storing a second video signal to be combined with the first video signal and a control signal indicating a combining start timing and a combining end timing of the second video signal for the first video signal;

(c) combining means for combining the second video signal with the first video signal in response to the control signal read out from the storing portion,

said combining means repeatedly combining the second video signal with the first video signal during a period in which said combining action is being instructed by the control signal; and

(d) recording means for recording a video signal output from said combining means,

3. An apparatus according to claim 1, further comprising a video camera for generating said first video signal.

4. An apparatus according to claim 1, wherein said first video signal includes a moving image signal and said second video signal includes at least one of a still image signal and a character signal.

5. An apparatus according to claim 1, wherein said storage portion is attachable and detachable relative to said apparatus.

6. A storing device for use in a video signal processing system, wherein said system combines a second video signal with a first video signal and includes a processing device for recording on a recording medium the combined video signals, comprising:

(a) storing means for storing the second video signal to be combined with the first video signal and a control signal indicating a combining start timing and a combining end timing of the second video signal for the first video signal; and

(b) output means for outputting to said combining device the second video signal and the control signal,

said processing device repeatedly combining the second video signal with the first video signal during a period in which said combining action is being instructed by the control signal output from said output means,

said control signal including a signal indicating a start of a recording action by the processing device,

said processing device recording the combined video signal during a period in which the recording action is being instructed by the control signal.

7. A device according to claim 6, wherein said processing device fades in and fades out said first video signal, storing means storing the control signal for controlling fading-in and fading-out of said first video signal effected by said fade operation.

8. A device according to claim 6, wherein said system includes a video camera for generating said first video signal.

9. A device according to claim 6, wherein said first video signal includes a moving image signal and said second video signal includes at least one of a still image signal and a character signal.

10. A storing device for use in a video signal processing system, including a processing device for combining a second video signal representing a predetermined object with a first video signal, comprising:

(a) storing means for storing the second video signal to be combined with the first video signal and a control signal for controlling said processing device; and

(b) output means for outputting to said processing device the second video signal and the control signal,

generating means for generating a third video signal representing an object different from the predetermined object,

said processing device having a first state in which the first video signal is combined with the second video signal output from said output means and a first combined video signal in obtained, a second state in which the first combined video signal is combined with the third video signal and a second combined video signal is obtained and a third state in which the first video signal is not combined with the second and third video signals,

said processing device changing a state of said processing device between the first, second and third states according to the control signal read out from the storing means.

11. A device according to claim 10, wherein said storage means stores the control signal for controlling terminating of the combining operation, said processing device controlling terminating of combining operation on the basis of the control signal.

12. A device according to claim 10, wherein said system includes a video camera for generating said first video signal.
