Abstract
A two-dimensional solid-state image pickup device wherein, in order to make it possible to have a high light detecting sensitivity even to feeble lights and to stably and uniformly detect picture images, picture elements each formed of a static induction transistor having an optical gain of 10.sup.6 to 10.sup.8 and able to detect even such feeble lights as of about 10.sup.-4 .mu.W/cm.sup.2 and a gate capacitor are arranged in a matrix to be a gate accumulating system capable of two-dimensional reading out, the source regions of the respective static induction transistors are connected to common source lines, the respective source lines are connected to the ground through parallelly connected source line selecting transistors and capacitors and the gates of the respective source line selecting transistors are connected respectively to vertical address lines so that, simultaneously with the selection of the vertical address lines, the source lines may be connected to the ground.
