Abstract
An imaging apparatus includes a first holding circuit, a second holding circuit, and a calculator. The first holding circuit is configured to hold and output a logical value based on a logical value supplied from an address decoder. The second holding circuit is configured to hold and output a logical value based on the logical value output from the first holding circuit. The calculator is configured to receive the logical values supplied from the first and second holding circuits and perform a logical operation for generating a driving signal.
Claims19
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.
