ABSTRACT:
An image pickup apparatus comprising: a plurality of pixels each with a photodiode, a logarithmic converter including a logarithmic-converting MOS transistor for converting an output of the photodiode into an electric signal proportional to a logarithmic value of an amount of incident light on the photodiode, and an integration circuit for accumulating an output from the logarithmic converter; a voltage controller for control of a voltage to be applied to the transistor; and an output circuit for receiving signals from the pixels and outputting processed signals. The voltage controller realizes a moving object extraction image pickup state in which an image pickup signal is generated for displaying at least a part of the moving object existing in an image picked-up region at a density different from that of a static background part.
