In this paper, a 4.0µm stacked digital pixel sensor (DPS), which has pixel parallel ADC structure are reported. In this DPS, conventional linear ADC mode and time stamp operation are automatically adapted for low and high illuminance conditions, which is called 2Q operation. Low power consumption, global shutter and 107dB high dynamic range have been achieved with this operation.
