Abstract
An imaging device includes a first chip on which a plurality of first blocks is arranged in a matrix, and a second chip which includes a first block scanning circuit and a second block scanning circuit. The second chip includes a selection circuit configured to select driving timing given to a plurality of pixels, based on a signal output from the first block scanning circuit and a signal output from the second block scanning circuit. A second block includes a circuit other than the selection circuit.
Claims18
An imaging device comprising:
- a first chip on which a plurality of first blocks is arranged in a matrix;
- and
- a second chip on which a plurality of second blocks is arranged in a matrix, the first and second chips being stacked;
- a first block scanning circuit configured to output a vertical block control signal for controlling the driving timing of the plurality of pixels arranged in a row direction;
- and
- a second block scanning circuit configured to output a horizontal block control signal for controlling the driving timing of the plurality of pixels arranged in a column direction,
- wherein each of the plurality of first blocks includes a plurality of pixels arranged in a matrix,
- wherein each of the plurality of second blocks includes a selection circuit for selecting driving timing of the plurality of pixels corresponding to one of the plurality of first blocks,
- wherein the selection circuit in each of the plurality of second blocks overlaps with the corresponding one of the plurality of first blocks in a plan view,
- wherein each of the plurality of second blocks includes an analog-to-digital (AD) converter configured to convert an analog signal output from the pixels into a digital signal,
- wherein the selection circuit is configured to select the driving timing of the plurality of pixels based on a combination of the vertical block control signal and the horizontal block control signal, and
- wherein the selection circuit is configured to individually control reading a signal of a first pixel arranged in a first row of one first block and reading a signal of a second pixel arranged in a second row of the one first block.
