Abstract

An image pick-up device which uses a charge transfer type solid state image pick-up device, and further is provided with a shutter so as to form a high quality picture signal in such a manner that smear is prevented by prohibiting the incidence of light on the device while the charge is being transferred in the device. Further, the device is driven by a clock signal for still photographing in order to obtain a high quality picture information for one frame. Further, the photographing parameter is automatically changed over or the monitor is changed over between the motion picture photographing mode and the still photographing mode.

Claims

1. An image pick-up device comprising:

(a) image pick-up means for converting an optical image into an electrical signal;

(b) control means having a first mode for causing said image pick-up means to generate signals for one image and a second mode for causing said image pick-up means to intermittently generate signals for a predetermined plurality of images; and

(c) exposure means for exposing said image pick-up means for a predetermined limited period in said first mode of said control means, and exposing said image pick-up means all the time in said second mode of said control means.

2. A device according to claim 1, wherein said signals for one image is one television field signal.

3. A device according to claim 1, wherein said signals for one image is one television frame signal.

4. A device according to claim 1, further comprising drive means for reading out said electrical signal from said image pick-up means at a predetermined interval of time.

5. An image pick-up device comprising:

(a) image pick-up means for converting an optical image into an electrical signal;

(b) control means having a first mode for causing said image pick-up means to generate signals for one image and a second mode for causing said image pick-up means to intermittently generate signals for a predetermined plurality of images;

(c) exposure condition setting means for setting different exposure conditions for said image pick-up means when said control means is in the first mode and when said control means is in the second mode; and

(d) exposure control means for controlling the exposure condition for said image pick-up means on the basis of an output of said setting means.

6. A device according to claim 5, wherein said signals for one image is one television field signal.

7. A device according to claim 5, wherein said signals for one image is one television frame signal.

8. An image pick-up device comprising:

(a) an image pick-up means for converting an optical image into an electrical image signal;

(b) recording means for recording said electrical image signal of said image pick-up means in response to actuation of an operating member; and

(c) display means for automatically reproducing and displaying a part of said electrical image signal recorded by said recording means for a predetermined period following said actuation of said operating member.

9. A device according to claim 8, wherein said display means is able to display motion picture images.

10. A device according to claim 8, further comprising erasing means for erasing recorded contents of said recording means.

11. A device according to claim 10, wherein said erasing means performs an erasure periodically.

12. An image pick-up device comprising:

(a) an image pick-up means for converting an optical image into an electrical signal;

(b) sample-and-hold means for sampling and holding at least a part of said electrical signal of said image pick-up means in response to actuation of an operating member; and

(c) control means for controlling an exposure condition against said image pick-up means by use of an output of said sample-and-hold means.

13. A device according to claim 12, further comprising mode control means having a first mode for causing said image pick-up means to form signals for one image, and a second mode for causing said image pick-up means to intermittently form signals for a plurality of images.

14. A device according to claim 13, wherein said sample-and-hold means performs the sampling and holding along with change over from said second mode to said first mode.

15. An image pick-up device comprising:

(a) image pick-up means for converting an optical image into an electrical signal;

(b) control means having a first mode for causing said image pick-up means to form signals for one image and a second mode for causing said image pick-up means to intermittently form signals for a plurality of images; and

(c) two switch members having a first switch for selecting said second mode and a second switch for selecting said first mode, said first switch operating in advance of said second switch.

16. An image pick-up device comprising:

(a) image pick-up means for converting an optical image into an electrical signal;

(b) recording means for recording said electrical signal of said image pick-up means;

(c) two switch members having a first switch for selecting a second mode and a second switch for selecting a first mode, said first switch operating in advance of said second switch; and

(d) control means having said first mode for causing recording of one image from the image pick-up means, and a second mode for causing recording of a plurality of images from said image pick-up means.

17. An image pick-up device comprising:

(a) image pick-up means for converting an optical image into an electrical signal;

(b) trigger signal generating means for generating a trigger signal for starting accumulation of predetermined picture images in said image pick-up means;

(c) read out means for clearing the picture image signals in said image pick-up means in response to the trigger signal, and for converting optical images into electrical signals and accumulating said signals in said image pick-up means for a predetermined period and reading out said accumlated electrical signals; and

(d) a shutter for cutting off light incidence on the image pick-up means, said shutter performing light shielding of said image pick-up means while said read out means performs the read-out, and allowing the exposure of said image pick-up means at least when the electrical signal is formed in said image pick-up means.

18. A device according to claim 17, further comprising recording means for recording the electrical signals read out by said read out means.
