To use the SSS Exporter, and generate a raw image and electron map, users need to have a Speos-generated Spectral Exposure map, or Irradiance map, and EMVA 1288 Standard sensor data. The tool then automatically processes this data to create valuable insights about camera sensor acquisition. To generate the electron map, the SSS Exporter utilizes External Quantum Efficiency (EQE) data of the imager, which can be obtained from Lumerical or the imager's datasheet. The article aims to showcase the extensive range of features and possibilities offered by the SSS Exporter tool. Each feature is demonstrated using practical examples, organized into folders and subfolders for easy execution. The tool doesn't have a graphical user interface, so understanding file management is crucial for proper usage. For further insights into SSS Exporter, it is recommended to explore the article of Getting started with Speos Sensor System Exporter and running your first example and CMOS Sensor Camera - Image Quality Analysis in a 3D Scene.

Understanding and quantifying thermal noise is crucial for camera sensor characterization and performance evaluation. This noise arises due to the thermal energy present in the sensor's components, leading to random fluctuations in signal levels. This intrinsic noise phenomenon in sensors, in low-light or high-gain scenarios, can significantly impact image quality, leading to reduced signal-to-noise ratio (SNR) and affecting the overall image clarity. Managing and minimizing thermal noise is essential in applications where high sensitivity and precision are required.SSS Exporter provides capabilities to experiment with sensor thermal noise as per the EMVA data. By incorporating thermal noise models into the simulation, SSS Exporter allows users to assess and evaluate sensor thermal noise performance under different operating conditions, including varying temperatures in operation condition using corresponding keys:

This is the effect of the “statistical noise”. It is proportional to the square root of the number of photons, hence, there is no noise in the top-left area of the sensor, since it contains no photons.

In summary, the article introduces Speos Sensor System Exporter capability for post-processing the camera simulation results in Speos based on the Camera Sensor feature. This article showcases practical examples that create electron maps and raw images based on the sensor's Reduced Order Model, aligned with EMVA 1288 Standard covering integration time, noise, coupling, etc., with generated results stored in specific folders. If you are looking for more insights on the development step of the tool, you can refer to Speos Sensor System Exporter - Development methods and capabilities.

Sensor Gain amplifies the captured signal, brightening the image, but it may also amplify noise, degrading image quality. Similarly, longer Exposure Time allows more light to reach the sensor, resulting in brighter images. However, longer exposures can lead to motion blur in dynamic scenes, necessitating a careful balance with the appropriate Gain setting.

An Optical SteadyShot Image Stabilization helps to minimize the effects of camera shake, allowing for sharper images when shooting handheld or in low light conditions. The autofocus while zooming supports continuous autofocus while zooming, ensuring smooth and fast focusing performance when adjusting focal length during shooting.

This example was built to highlight the photon noise from the SSS Exporter. It was integrated inside the tool to give more accurate results on homogeneous areas from Speos map, since it’s rare that a real sensor measures the exact same number of photons on multiple pixels. The starting map is an exposure map that only contains homogeneous areas.

Dark Signal Non-Uniformity (DSNU): DSNU accounts for the variation in dark signal levels among individual pixels in an image sensor when no light is incident on the sensor. Calibrating DSNU as shown below has been useful for eliminating unwanted dark signal variations. This calibration can help in ensuring the accuracy and reliability of image data, particularly in challenging lighting scenarios.

SSS Exporter was originally built to generate sensor images based on the EMVA1288 standard, built to characterize sensor images. However, this standard makes one main assumption about the sensor, which is that the quantum efficiency is wavelength-dependent only and is homogeneous through the sensor area. This might not be true for many sensors. Indeed, the quantum efficiency of the pixels usually depends on the light incidence which is not the same on each pixel of the sensor. Therefore, the real quantum efficiency can be seen as a function of the wavelength and the light incidence (or the position on the pixel matrix).Such an advanced quantum efficiency can be computed thanks to Ansys Lumerical. . You can use it to design the pixel matrix accurately and export the quantum efficiency in a JSON file. More information about this procedure can be found in this CMOS Sensor Camera- Sensor Characterization article. The SSS Exporter will read this JSON file as input, and it will be used to replace the EMVA1288 standard inputs.There are two available modes for the Lumerical files:Mode 1: QE as a function of incidenceThis mode is limited to a lens system with revolution axis. Inside the mode 1 JSON file the QE is defined as a 3D matrix: incidence vs wavelength vs Bayer matrix.Mode 2: QE as a function of position on the sensorThis mode can be used with any lens system. Inside the mode 2 JSON file the QE is defined as a 3D matrix: pixel position vs wavelength vs Bayer matrix.In the sensor .yaml file, the Lumerical input is specified under the “Lumerical data” key. You can specify 2 subkeys: “Mode” (V1 or V2) and “Filename” (name of the Lumerical JSON file).

The Speos Sensor System Exporter (SSS Exporter) is a powerful tool designed for the post-processing of camera simulation results from Speos. The tool transforms the Spectral Exposure/Irradiance map which represents illuminance/irradiance values reaching the camera sensor, into a raw image, an electron map, and a developed image. The transformation from photometric result to electron map and raw image are based on a Reduced Order Model of the sensor, adhering to the EMVA 1288 standard (release 3.1). EMVA 1288 is an industry-standard specification that characterizes image sensor performance for machine vision and imaging applications. It provides standardized tests for key sensor parameters like responsivity, dynamic range, noise, dark current and quantum efficiency.

Note: Quantum efficiency can be an input from simulation, such as data calculated with Ansys Lumerical that has been exported to a *.json file. In this case, IR & UV Filter, Quantum Efficiency, and Bayer Matrix sub-keys in the EMVA data key are ignored.

Photo-Response Non-Uniformity (PRNU): PRNU which refers to the sensitivity variation across pixels of an image sensor can cause slight differences in pixel response to the same incident light intensity. As shown in this example, the calibration of PRNU can have an impact on correcting these sensitivity variations and resulting in more accurate and consistent pixel responses.

Go-anywhere agility and mobilityThe E PZ 16–50 mm F3.5–5.6 OSS II retracts to a total length of just 31.3 mm (1.25 in) when camera power is turned off. In addition to its diminutive size and low weight of just 107 grams (3.8 oz.), it is a durable lens that can withstand the rigors of day-to-day shooting.

In the context of image sensor characterization, most of the parameters discussed so far have focused on individual pixels or their average behavior. However, it's essential to recognize that the parameters of an array of pixels can vary from one pixel to another.For linear sensors, two fundamental nonuniformities play a crucial role in image quality: Photo-Response Non-Uniformity (PRNU) and Dark Signal Non-Uniformity (DSNU). These variations can introduce non-uniformities in pixel sensitivity and dark signal levels, leading to unwanted noise and artifacts in the images. SSS Exporter provides the capability to experiment and calibrate sensor characteristics like PRNU and DSNU. By incorporating the EMVA Data and relevant sub-keys into its simulations, SSS Exporter allows users to explore the effects of these non-uniformities on image quality.
