Claims
- 1. A video camera apparatus comprising:
- (A) an optical system, including a zooming lens and a focusing lens for compensating a variation of a focal position due to a movement of said zooming lens, for forming an image;
- (B) a camera part for converting the image formed by said optical system into an image signal and outputting the image signal;
- (C) initializing means, in response to POWER-ON, for performing an initialization operation of said optical system by moving said zooming lens to a first resetting position and moving said focusing lens to a second resetting position;
- (C') generating means for generating a predetermined signal for displaying on the initializing operation;
- (C") detecting means for detecting a completion of the initializing operation; and
- (D) controlling means, in response to POWER-ON, for controlling an output signal of said camera part to inhibit outputting of the image signal corresponding to said image and to place the output signal in the predetermined signal output from said generating means, and in response to an output of said detecting means to permit said camera part to output the image signal.
- 2. A video camera apparatus according to claim 1, wherein said controlling means fades said output signal of said camera part in association with the initialization operation.
- 3. A video camera apparatus according to claim 2, wherein said controlling means controls the output signal of said camera part to place said output signal in a state representative of a picture made all in single color.
- 4. A video camera apparatus according to claim 1, wherein said optical system is an inner focus type lens system.
- 5. A video camera apparatus according to claim 4, wherein said initializing means performs an operation for adjusting a follow-up speed at which said focusing lens is made to move in follow-up relation to a movement of said zooming lens.
- 6. A video camera apparatus according to claim 1 or 5, wherein said initializing means starts the initialization operation when a power source is turned on.
- 7. A video camera apparatus according to claim 2, wherein said controlling means places the output signal of said camera part in a state representative of a picture made all in single color during the initialization operation of said initializing means.
- 8. A video camera apparatus comprising:
- (A) an optical system, including a zooming lens and a focusing lens for compensating a variation of a focal position due to a movement of said zooming lens, for forming an image;
- (B) a camera part for converting the image formed by said optical system into an image signal and outputting the image signal;
- (C) an electronic monitor for providing a visual display of an output signal of said camera part;
- (D) initializing means, in response to POWER-ON, for performing an initialization operation of said optical system by moving said zooming lens to a first resetting position and moving said focusing lens to a second resetting position;
- (D') generating means for generating a predetermined signal for displaying on the initializing operation;
- (D") detecting means for detecting a completion of the initializing operation; and
- (E) controlling means, in response to POWER-ON, for controlling an image displayed in said electronic monitor during said initialization operation to inhibit the outputting of said image signal output from said camera part to be supplied to said electronic monitor and to place an image displayed in said electronic monitor in the predetermined signal output from said generating means, and in response to an output of said detecting means to permit the outputting of said image signal.
- 9. A video camera apparatus according to claim 8, wherein said controlling means controls an output signal of said camera part to place the output signal in a state representative of a picture made all in single color.
- 10. A video camera apparatus according to claim 9, wherein said initializing means starts the initialization operation when a power source is turned on, said controlling means controlling the output signal of said camera part to place said output signal in a state representative of a picture made all in single color during the initialization operation of said initializing means.
- 11. A video camera apparatus according to claim 8, wherein said optical system is an inner focus type lens system.
- 12. A video camera apparatus according to claim 11, wherein said initializing means performs an operation for adjusting a follow-up speed at which said focusing lens is made to move in follow-up relation to a movement of said zooming lens.
- 13. A video camera apparatus comprising:
- (A) a lens unit, including a zooming lens and a focusing lens for compensating a variation of a focal position due to a movement of said zooming lens, for forming an image;
- (B) a camera part for converting the image formed by said optical system into an image signal and outputting the image signal;
- (B') generating means for generating a predetermined signal unrelated to the image signal;
- (C) a recorder part for applying predetermined processing to the image signal outputted from said camera part and recording said processed image signal;
- (D) resetting means, in response to POWER-ON, for performing a reset operation of said lens unit by moving said zooming lens to a first resetting position and moving said focusing lens to a second resetting position;
- (E) monitoring means for monitoring the image signal output from said camera part; and
- (F) controlling means, in response to POWER-ON, for outputting a control signal during the reset operation for inhibiting said recorder part from performing a recording operation in response to the control signal and for supplying the predetermined signal for indicating the resetting operation being executed to said monitoring means and in response to a completion of the reset operation to permit a recording operation.
- 14. A video camera apparatus according to claim 13, wherein said lens unit is an inner focus type lens unit.
- 15. A video camera apparatus according to claim 14, wherein said resetting means performs an operation for adjusting a follow-up speed of said focusing lens relative to a moving speed of said zooming lens.
- 16. A video camera apparatus according to claim 13, wherein said controlling means includes first muting means responsive to the control signal for muting a signal to be supplied from said camera part to said recorder part.
- 17. A video camera apparatus according to claim 16, wherein said controlling means includes second muting means responsive to the control signal for muting an image signal to be supplied to said monitor means.
