Abstract

In the disclosed picture recording device, an image pick-up arrangement converts an optical image into electric picture information and stores the information. A recording arrangement reads out the electric picture information on the image pick-up arrangement and records the information. A power supply control controls the power supply to the recording arrangement and a memory holds the electric picture information formed on the image pick-up arrangement at the start of the supply of power by the power supply control to the recording arrangement. This allows image information immediately to be picked up when the camera is turned on during the power up of the various camera circuits and thus avoids the loss of image information during the rise time.

Claims

1. A picture recording device, comprising:

image pick-up means having a light sensing portion for converting an optical image into an electrical picture information signal;

means for selectively shielding said light sensing portion during read-out of the electrical picture information;

means for recording the electrical picture information on a recording medium;

trigger means for starting powering said image pick-up means and said recording means;

means for detecting a rise of said recording means; and

control means for controlling said image pick-up means to form a first picture image signal in response to an actuation of said trigger means and store said first picture image signal until the rise of said recording means to provide a stored first picture image signal and controlling said recording means to record said stored first picture image signal after the rise of said recording means to thereby save power consumption and avoid loss of shutter chance.

2. A picture recording device in accordance with claim 1, wherein said image pick-up means has a memory portion for storing the electrical picture information, said picture recording device comprising means for varying timing of transferring of the electrical picture information from said light sensing portion to said memory portion.

4. A picture recording device in accordance with claim 1, wherein the detecting means includes a timer.

3. A picture recording device, comprising:

image pick-up means having a light sensing portion for converting an optical image into an electrical picture information signal;

means for selectively shielding said light sensing portion during read out of the electrical picture information;

means for recording the electrical picture information on a recording medium;

trigger means for starting powering said image pick-up means and said recording means;

means for detecting a rise of said recording means;

power means for supplying power to said recording means; and

control means for controlling said image pick-up means to form a first picture image signal in response to an actuation of said trigger means and store said first picture image signal until the rise of said recording means and controlling said reading means to read said first picture image signal from said image pick-up means after the rise of said recording means to be recorded by said recording means, thereby saving power consumption and avoiding loss of shutter chance.

5. A device according to claim 3, wherein said image pick-up means is made of a semiconductor material.

6. A device according to claim 3, further including means for varying and controlling the time of the converting operation of said image pick-up means.

7. A device according to claim 3, wherein said control means transfers the electrical picture information signal produced in said light sensing portion to a prescribed portion in said image pick-up means so that light does not affect the electrical picture information signal in said image pick-up means until the rise of said recording means.

8. A recording apparatus, comprising:

image pick-up means for photoconverting an optical image into an electrical signal;

trigger means for starting powering said image pick-up means and said recording means;

recording means for recording an output of said image pick-up means; and

control means for controlling said image pick-up means to form a first picture image signal in response to an actuation of said trigger means, to store said first picture image signal until a rise of said recording means and to output said first picture image signal to be recorded by said recording means after the rise of said recording means, thereby saving power consumption and avoiding loss of shutter chance.

9. An apparatus according to claim 8, further comprising:

shielding means for shielding said image pick-up means.

10. An apparatus according to claim 8, further comprising:

common trigger means for powering said recording means and said image pick-up means.

11. An apparatus according to claim 8, wherein the rise of said recording means occurs when servo-locking is substantially completed a predetermined time after said recording means is powered.

12. A recording apparatus, comprising:

image pick-up means for photoconverting an optical image into an electrical signal;

trigger means for starting powering said image pick-up means and said recording means;

recording means for recording an output of said image pick-up means; and

control means for controlling said image pick-up means to form a first picture image signal in response to an actuation of said trigger means, to store said first picture image signal by shielding said image pick-up means at least until a rise of said recording means and to output said first picture image signal to be recorded by said recording means after the rise of said recording means, thereby saving power consumption and avoiding loss of shutter chance.

13. An apparatus according to claim 12, further comprising:

shielding means for shielding said image pick-up means.

14. An apparatus according to claim 12, further comprising:

common trigger means for powering said recording means and said image pick-up means.

15. An apparatus according to claim 12, wherein the rise of said recording means occurs a predetermined time after being powered.
