Sony IMX410 Sensitivity

The sensor G sensitivity is 572.76mV with 1/30s. Its spectral sensitivity is shown in Figure2

14Bit ADC and ROI

It has built in 14bit ADC. It also has 12bit output mode for hardware binning and smaller resolution. The
camera also supports hardware ROI, and the smaller the ROI size is, the faster frame rate is.

DDR3 Buffer

The camera has a 512MB (4Gb) DDR3 buffer, which helps maintain the stability of data transmission, and effectively reducing the amp-glow caused because image data can be temporarily buffered without being sent hastily to the receiver.


Binning
The camera supports digital binning from 1´1 to 8´8 in either stacking or averaging method, and hardware binning from 1´1 to 3´3 in averaging method.Hardware pixel binning is much faster than software binning. Conversion Gain Switch
It supportsHCGandLCGmode switch. UnderHCGmode, the readout noise could
reach 0.3 e- at maximum gain setting. Power and Cooling System for Precise Temperature Regulation
The cooling system is two-stageThermoelectric Cooling(TEC) with controllable electric fan assisting heat dissipation. The working temperature can be regulated to specific number, and effective temperature drop can be -35°C from ambient temperature. Such efficient cooling system guarantees the stability of ultra-low noise mode and quality of the camera image.
The TEC system is controlled by PID algorithm, which allows the TEC to be precisely regulated towards the target temperature with 0.1C deviation. Zero Amp-Glow
The camerahas been carefully designed and is able to achieve zero amp-glow photo shooting.Figure3Amp-glow.andFigure4show the different cameras at 20°C and 5-minute exposure time with and without amp-glow. One can find that captured image has zero amp-glow.

Camera Performance Analysis

Camera performance can be evaluated withe-/ADU,Read Noise,Full WellandDynamic Range.e-/ADU: The sensors found in cameras used for vision applications have pixels that convert incoming photons into electrons. Gain on a CCD /CMOS camera represents the conversion factor from electrons (e-) into digital counts, orAnalog-Digital Units(ADUs). Gain is expressed as the number of electrons that get converted into a digital number, or electrons perADU(e-/ADU).


Read Noise: Read Noise is the most important reference to measure the performance of a camera. Lower read noise usually means better SNR and better quality of image.Read Noiseis created within the camera electronics during the readout process as the electrons are subjected to the analog to digital conversion, amplification and processing steps that enable an image to be produced.


Full Well: The electrons are held in each pixel and are converted into electrical charge which can be measured to show the amount of
light that has fallen on each pixel. The maximum electrical charge possible is termed "full well capacity". Under the same conditions such as noise and A/D converter quality, the greater full well capacity a sensor has, the wider dynamic range the sensor has. As there is a limit to the depth to which pixels can be made, the full well capacity is often proportional to the frontal area of the light gathering element of the pixel.


Dynamic Rangeis the ratio between the maximum output signal level and the noise floor at minimum signal amplification (noise floor
which is the RMS (root mean square) noise level in a black image). The noise floor of the camera contains sensor readout noise, camera processing noise and the dark current shot noise.Dynamic rangerepresents the camera's ability to display/reproduce the brightest and darkest portions of the image and how many variations in between. This is technically intra-scene dynamic range. Within one image there may be a portion that is in complete black and a portion that is completely saturated.


It has a significantly low read noise: 0.9 - 1.72 e- (Low Noise Mode). It is more impressive that this camera comes with low noise mode, which means users could get even lower readout noise by selecting low noise mode while the frame rate only drops a little as sacrifice.
