摘要： The present disclosure relates to an imaging apparatus and an imaging method, a camera module, and an electronic apparatus that are capable of detecting a failure in an imaging device having a structure in which a plurality of substrates are stacked.
The timing at which a row drive unit provided in a second substrate outputs a control signal for controlling accumulation and reading of pixel signals in a pixel array provided in a first substrate is compared with the timing at which the control signal output from the row drive unit is detected after passing through the pixel array. Depending on whether or not the timings coincides with each other, a failure is detected. The present disclosure can be applied to an imaging apparatus mounted on a vehicle.-

摘要： In one example, an imaging device including a plurality of pixel circuits, a first control line, a second control line, a first voltage supply line, a second voltage supply line, a first light-receiving element, and a diagnosis unit is disclosed. The pixel circuits each include a first terminal, a second terminal, a third terminal, an accumulation unit, a first transistor, a second transistor, and an output unit. The first transistor is couples the third terminal to the accumulation unit on the basis of a voltage of the first terminal. The second transistor supplies a predetermined voltage to the accumulation unit on the basis of a voltage of the second terminal. The output unit outputs a signal corresponding to a voltage in the accumulation unit.
