To shorten time required for AD conversion when a solid-state imaging element that detects presence or absence of an address event further captures image data. In a detection block, a first pixel that generates a first analog signal by photoelectric conversion and a second pixel that generates a second analog signal by photoelectric conversion are arrayed. A first analog-digital converter converts the first analog signal into a digital signal on the basis of whether or not a change amount of an incident light amount of the detection block exceeds a predetermined threshold. A second analog-digital converter converts the second analog signal into a digital signal on the basis of whether or not the change amount exceeds the threshold.

A photoelectric converter includes pixels, vertical output lines to which a signal is outputted from the pixels, clippers configured to limit a potential of the output lines and a controller. Each of the clippers includes a first circuit configured to output an amplification signal according to a predetermined potential and the potential of the output line and a second circuit configured to supply a current according to the amplification signal to the output line. The controller controls each of the clippers to a state selected from states including a first state in which a range in which the potential of the output line can change is limited using the first and second circuits, and a second state in which the range in which the potential of the vertical output line can change is limited with an output of the second circuit deactivated.

In a pixel 200, a floating diffusion FD11 and a first capacitor CS11 are selectively connected to each other via a first connection element LG11-Tr, to change the capacitance of the floating diffusion FD11 between a first capacitance and a second capacitance, thereby changing the conversion gain between a first conversion gain (HCG) corresponding to the first capacitance and a second conversion gain (MCG) corresponding to the second capacitance. The floating diffusion FD11 and a second capacitor CS12 are connected together through a second connection element SG11-Tr to change the capacitance of the floating diffusion FD11 to a third capacitance, thereby changing the conversion gain of the source following transistor SF11-Tr to a third conversion gain (LCG) corresponding to the third capacitance

Provided is an imaging device in which a subject moving within a visual field can be freely expressed with a simple configuration. This imaging device is an imaging device which acquires an image by dividing one imaging period into a plurality of periods for exposure to add for each pixel, and includes an imaging element which includes a photoelectric conversion unit configured to generate a signal charge, and a control unit configured to control an accumulation time of the signal charge generated in the photoelectric conversion unit. The control unit changes the accumulation time in each period obtained by dividing the one imaging period.

Correlated double sampling column-level readout of an image sensor pixel may be provided by a charge transfer amplifier that is configured and operated to itself provide for both correlated-double-sampling and amplification of floating diffusion potentials read out from the pixel onto a column bus after reset of the floating diffusion (I) but before transferring photocharge to the floating diffusion (the reset potential) and (ii) after transferring photocharge to the floating diffusion (the transfer potential). A common capacitor of the charge transfer amplifier may sample both the reset potential and the transfer potential such that a change in potential (and corresponding charge change) on the capacitor represents the difference between the transfer potential and reset potential, and the magnitude of this change is amplified by the charge change being transferred between the common capacitor and a second capacitor selectively coupled to the common capacitor.

The dynamic range control unit sets, in accordance with a result of the detection of the saturated region, a dynamic range of the infrared imaging device to a first temperature range, or a second temperature range where a temperature at least on an upper limit side is higher than that in the first temperature range. The shutter control unit controls opening and closing of a shutter for protecting the infrared imaging device based on the result of the detection of the saturated region and the setting of the dynamic range.
