Abstract
Abstract A position detector detects the presence of a travelling foreground subject and then enables a light projector, such as a Strobo tube, to provide short duration flashes when the foreground subject is at an optimum predetermined position relative to the position of the light projector. A photoelectric conversion device is provided to pick up an image of the illuminated foreground subject, signals corresponding to the picked up image being processed and, if desired, stored to provide a permanent record.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
An image pickup apparatus comprising: means for detecting the position of a travelling foreground subject and for generating a corresponding signal; means for projecting short duration light flashes on said foreground subject; delay means for delaying the signal generated by said position detecting means and for enabling said light projecting means a predetermined time after detection of said travelling foreground subject, to thereby project said light flashes when said travelling foreground subject is located at a predetermined position; photoelectric means for picking up an image of said foreground subject illuminated by light flashes and for storing the picked up image; and output utilization means coupled to said photoelectric means and responsive to the output thereof which corresponds to said picked up image.
Claim 2
Dependent Claim
122 words
An image pickup apparatus comprising: means for detecting the position of a travelling foreground subject and for generating a corresponding signal; means for projecting short duration light flashes on said foreground subject; delay means for delaying the signal generated by said position detecting means and for enabling said light projecting means a predetermined time after detection of said travelling foreground subject, to thereby project said light flashes when said travelling foreground subject is located at a predetermined position; photoelectric means for picking up an image of said foreground subject illuminated by light flashes and for storing the picked up image; and output utilization means coupled to said photoelectric means and responsive to the output thereof which corresponds to said picked up image.
Claim 3
Dependent Claim
24 words
Apparatus according to claim 1 wherein said output utilization means includes a magnetic recording device for recording signals corresponding to said picked up image.
Claim 4
Dependent Claim
48 words
Apparatus according to claim 1 comprising a source of horizontal and vertical synchronizing signals, the vertical synchronizing signal including blanking periods, and wherein said photoelectric means includes a photoelectric conversion plane and means for scanning said photoelectric conversion plane by electron beams under control of said synchronizing signals.
Claim 5
Dependent Claim
32 words
Apparatus according to claim 3 wherein said photoelectric means further includes means responsive to said position detecting means for temporarily applying electron beams prior to the enabling of said light projecting means.
Claim 6
Dependent Claim
38 words
Apparatus according to claim 3 wherein said scanning means further comprises means for continuing the electron beam scanning after a picked up image signal has been taken out so as to eliminate the residual images on said plane.
Claim 7
Dependent Claim
49 words
Apparatus according to claim 3 wherein said scanning means includes means for scanning said plane in a vertical as well as horizontal direction thereof by the electron beams, and means for enabling said light projecting means to project light flashes during the blanking period of the vertical synchronizing signal.
Claim 8
Dependent Claim
20 words
Apparatus according to claim 3 wherein said scanning means includes means for applying interlaced electron beam scanning to said plane.
Claim 9
Dependent Claim
21 words
Apparatus according to claim 3 wherein said photoelectric means further comprises biasing light means for projecting light uniformly on said plane.
