Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
94 words
An instantaneous camera comprising a lens system; a solid state array imaging device having discrete light sensitive points whose accumulated charge is a function of the incident light; means for positioning said imaging device in predetermined relationship with said lens system; means for sensing charges at said points and generating in predetermined order a sequence of pulses whose amplitudes are a function of the respective instantaneous charges at said points; a printer responsive to said pulses and having means for direct production of visible marks; and means coupling said last-said means to said printer.
Claim 2
Dependent Claim
94 words
An instantaneous camera comprising a lens system; a solid state array imaging device having discrete light sensitive points whose accumulated charge is a function of the incident light; means for positioning said imaging device in predetermined relationship with said lens system; means for sensing charges at said points and generating in predetermined order a sequence of pulses whose amplitudes are a function of the respective instantaneous charges at said points; a printer responsive to said pulses and having means for direct production of visible marks; and means coupling said last-said means to said printer.
Claim 3
Dependent Claim
18 words
A camera as described in claim 1 including means maintaining the said imaging device substantially below ambient temperature.
Claim 4
Dependent Claim
43 words
A camera as described in claim 1 wherein said coupling means includes an analog-to-digital converter and a solid state memory device whereby said pulses are stored as digital data for a time sufficient to permit effective recording of said data by said printer.
Claim 5
Dependent Claim
28 words
A camera as described in claim 3 wherein said memory has a retention time significantly in excess of the printing time of said printer for one complete image.
