MOS-type solid-state imaging apparatus

摘要

In an MOS-type solid-state imaging apparatus, plural unit cells are arranged in a two-dimensional matrix, unit cells in one horizontal line (row) are selected by a vertical address circuit, and vertical signal lines to which outputs from the unit cells in one vertical line (column) are supplied are selected by a horizontal address circuit, thereby sequentially outputting signals from the respective unit cells. Each unit cell includes an output circuit for outputting an output from a photodiode to a vertical signal line, photodiodes connected in parallel to the output circuit, and a selection switch for selecting one of the photodiodes and connecting it to the output circuit. The output circuit comprising an amplification transistor for amplifying an output from the photodiode, a selection transistor for selecting the unit cell, and a reset transistor for resetting the charge in the photodiode.
