Abstract
A unit cell array is formed of unit cells arranged one-dimensionally or two-dimensionally, each unit cell having a photodiode, and first and second switches with one terminal of each switch connected to the photodiode. The other terminals of the first switches of the unit cells are connected to integrators that detect the integrated value of the charge generated by the incident light into the photodiodes, and the other terminals of the second switches of the unit cells are commonly connected to a signal line. The other end of the signal line is connected to a current detector that detects, as a current value, charge generated by light incident to the unit cell array. This arrangement results in a solid-state image pickup apparatus which is provided with means integrated on-chip with a sensor and operated within the same power supply voltage range as the sensor, and capable of detecting brightness on the sensor.
