Abstract: An image sensor may include active pixel rows that are used to generate image signals in various modes of operation. The active pixel rows may receive control signals that have corresponding sets of transitions. These sets of transitions may occur during readout operations for some active pixel rows but not during readout operations for other active pixel rows, especially in the case where frames of multiple types are generated by the same pixel array in an interweaved manner.

To mitigate these adverse effects, an image sensor may include dummy pixel rows that continuously pulse the sets of transitions during the readout operation of any active pixel row to ensure that the readout operations for all active pixel rows have the same readout environments.

Abstract: The present disclosure relates to a solid-state imaging element with which electric power consumption can be reduced, a method for operating the solid-state imaging element, an imaging device, and electronic equipment. After a signal output is outputted from a driver in an Nth row according to a selection signal from a vertical scanning unit, switchover is performed to transmit a signal output from a driver in an (N+1) row. Before the switchover, the drivers in the Nth and (N+1)th rows are brought into a floating state, and control signal lines to which the signal outputs from the drivers are transmitted are short-circuited for charge dispersion. This increases a potential of the control signal line of the next (N+1)th row to an intermediate potential. Thereafter, the driver in the (N+1)th row outputs the signal output. With this, the driver in the (N+1) row only needs to increase the potential from the intermediate potential to Hi level. This can reduce electric power consumption.
