Abstract
Abstract A solid state image pick-up device comprises a charge storage section for storing the charge corresponding to an image pattern, and a read-out section for reading out the stored charge in this charge storage section. The read-out section is connected to an output of the charge storage section and has a junction type field effect transistor to read out the stored charge as a picture signal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
93 words
A solid state image pick-up device comprising: a charge storage and transfer means for storing a signal charge corresponding to an image pattern, and for transferring said stored signal charge so as to issue an output corresponding to said stored signal charge; and reading out means for reading out the stored signal charge in said charge storage means as a picture signal, said reading out means including an output transistor comprising a junction type field effect transistor (J-FET) having a gate region connected to an output of said charge storage and transfer section.
Claim 2
Dependent Claim
93 words
A solid state image pick-up device comprising: a charge storage and transfer means for storing a signal charge corresponding to an image pattern, and for transferring said stored signal charge so as to issue an output corresponding to said stored signal charge; and reading out means for reading out the stored signal charge in said charge storage means as a picture signal, said reading out means including an output transistor comprising a junction type field effect transistor (J-FET) having a gate region connected to an output of said charge storage and transfer section.
