Imaging apparatus and imaging system having logical circuit to generate pixel driving signals

An imaging apparatus comprising:

• a pixel area including a plurality of pixel circuit groups each of which includes a plurality of pixel circuits;
• a plurality of drivers arranged so as to correspond to the different pixel circuit groups and configured to output driving signals to the corresponding pixel circuit groups;
• and
• an address decoder configured to supply logical values indicating selection or deselection of the individual drivers to the drivers,
• wherein each of the drivers includes
• a first holding circuit configured to hold and output a logical value based on a logical value supplied from the address decoder,
• a second holding circuit configured to hold and output a logical value based on the logical value output from the first holding circuit, and
• a calculator configured to receive the logical values supplied from the first and second holding circuits and perform a logical operation for generating one of the driving signals.
