Abstract
Abstract An image storage device in which stored information read out from each non-destructive readout picture element cell of a photoelectric converter is applied at a first scanning speed to a visual display unit to produce a visible image and the information is also supplied at a lower second scanning speed to a recorder. Switching or branching means is provided for applying the information from the photoelectric converter to the visual display unit and the recorder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
An image storage device comprising: a photoelectric converter having an arrangement of a plurality of non-destructive readout picture element cells, each for producing a stored information signal which can be read out without destruction; a visual display unit for receiving a readout stored information signal of each picture element cell at a first scanning speed to produce a visible image; a recorder for recording a readout stored information signal of each picture, at a second scanning speed which is lower than the first scanning speed to record a visible image; and switching means connected to said photoelectric converter, said visual display unit and said recorder for supplying each of said visual display unit and said recorder with the readout stored information signal of each picture element cell, respectively, at said first and said second scanning speeds.
Claim 2
Dependent Claim
136 words
An image storage device comprising: a photoelectric converter having an arrangement of a plurality of non-destructive readout picture element cells, each for producing a stored information signal which can be read out without destruction; a visual display unit for receiving a readout stored information signal of each picture element cell at a first scanning speed to produce a visible image; a recorder for recording a readout stored information signal of each picture, at a second scanning speed which is lower than the first scanning speed to record a visible image; and switching means connected to said photoelectric converter, said visual display unit and said recorder for supplying each of said visual display unit and said recorder with the readout stored information signal of each picture element cell, respectively, at said first and said second scanning speeds.
Claim 3
Dependent Claim
46 words
An image storage device according to claim 1 wherein said switching means includes a mechanism by which a scanning speed for reading out the stored information signal from each picture element cell of the photoelectric converter is changed over between said first and second scanning speeds.
Claim 4
Dependent Claim
92 words
An image storage device according to claim 2 wherein said switching means comprises an exposure readout controller including a first readout clock oscillator operating at the first scanning speed; a second readout clock oscillator operating at the second scanning speed, said mechanism including a clock selection switch connected to said first and second oscillators for selecting one of said oscillators for connection to said visual display unit and said recorder, and a further switch for connecting one of said visual display units and said recorder to said photoelectric converter at a time.
Claim 5
Dependent Claim
110 words
An image storage device according to claim 1 wherein said switching means comprises an exposure readout controller including a clock oscillator for supplying the first scanning speed, a frequency divider connected to said clock operator for supplying the second scanning speed, a first data line connected between said photoelectric converter and said visual display unit for carrying the stored information signal of each picture element cell, a sampler connected to said frequency divider, said data line and said recorder for supplying the stored information signal to said recorder at the second scanning speed while the stored information signal is supplied to said visual display unit at the first scanning speed.
Claim 6
Dependent Claim
128 words
An image device comprising: a photoelectric converter having an arrangement of a plurality of non-destructive readout picture element cells each for producing a stored information signal which can be read out without destruction; a visual display unit for receiving a readout stored information signal of each picture element cell at a first scanning speed to produce a visible image; a recorder for recording a further readout stored information signal of each picture element cell at a second scanning speed which is lower than the first scanning speed to record a visible image; and sampling means connected to said photoelectric converter, said visual display unit and said recorder for simultaneously supplying said visual display unit and said recorder with the readout stored information signal of each picture element cell.
Claim 7
Dependent Claim
128 words
An image device comprising: a photoelectric converter having an arrangement of a plurality of non-destructive readout picture element cells each for producing a stored information signal which can be read out without destruction; a visual display unit for receiving a readout stored information signal of each picture element cell at a first scanning speed to produce a visible image; a recorder for recording a further readout stored information signal of each picture element cell at a second scanning speed which is lower than the first scanning speed to record a visible image; and sampling means connected to said photoelectric converter, said visual display unit and said recorder for simultaneously supplying said visual display unit and said recorder with the readout stored information signal of each picture element cell.
Claim 8
Dependent Claim
46 words
An image storage device according to claim 5 wherein said sampling means includes a mechanism by which a scanning speed for reading out the stored information signal from each picture element cell of the photoelectric converter is changed over to the first and second scanning speeds.
