Image recording system

Claim 1

An image recording system comprising: (a) an optical-electronic image transducer having storage capability for storing an optical image as an electrical signal; (b) release means; (c) a release signal forming circuit for producing a release signal when said release means is actuated; (d) an exposure control timer circuit operative in response to said release signal, said timer circuit including a light-receiving element, said timer circuit being arranged for producing signals at time intervals based on the brightness of light received at said light receiving element; (e) a control circuit coupled to said image transducer, said control circuit being arranged to cause said image transducer to begin a storing operation in response to said release signal, said control circuit being further arranged to have said storing operation stopped in response to a signal of said timer circuit and to have another storing operation commenced so that the storing operation can be carried out in a continuously repeating manner at time intervals defined by said timer circuit; (f) a recording circuit for recording the optical image stored during a time regulated by said timer circuit; and (g) a mode control circuit for switching between first and second modes, said recording circuit being arranged to perform a recording operation in a continuously repeating manner every time a signal of said timer circuit is produced in the first mode and to singly perform the recording operation in response to each issue of a signal produced by said timer circuit in the second mode.

Claim 4

A system for performing a flash exposure with a flash device having light measuring means that measure a flash of light reflected by an object to be photographed and is arranged to produce a signal when the amount of the light measured by said light measuring means reaches a predetermined value, said system comprising: (a) an optical-electronic image transducer having storage capability for storing an optical image as an electrical signal; (b) a release; a control circuit coupled to said transducer, said control circuit being arranged to have a storing operation commenced by said transducer in response to the operation of said release, said control circuit being further arranged to have said storing operation stopped in response to the signal produced by said flash device; and (c) trigger signal producing means arranged to transmit a trigger signal to said flash device to have said flash device generate a flash of light in synchronism with the storing operation performed by said transducer.

Claim 5

A system for performing a flash exposure with a flash device having light measuring means that measure a flash of light reflected by an object to be photographed and is arranged to produce a signal when the amount of the light measured by said light measuring means reaches a predetermined value, said system comprising: (a) an optical-electronic image transducer having storage capability for storing an optical image as an electrical signal; (b) a release; a control circuit coupled to said transducer, said control circuit being arranged to have a storing operation commenced by said transducer in response to the operation of said release, said control circuit being further arranged to have said storing operation stopped in response to the signal produced by said flash device; and (c) trigger signal producing means arranged to transmit a trigger signal to said flash device to have said flash device generate a flash of light in synchronism with the storing operation performed by said transducer.
