Imatest Simatest Camera performance simulator based on information theory

Fri, 07 Nov 2025 00:00:00 +0000

Norman Koren describes a camera performance simulator that includes an image sensor noise model with parameters derived from either dynamic range test chart measurements or EMVA 1288 results. The simulator includes lens degradations and the effects of Image Signal Processing (ISP). Results can be analyzed for standard image quality metrics such as sharpness and noise, or new metrics, derived from information theory, that provide an improved prediction of machine vision system performance.

Simatest Demo

Henry Koren — Thu, 15 May 2025 00:00:00 +0000

Imatest 25.1 introduces Simatest, which simulates complete camera systems, including the effects of lens degradations, image sensor noise, and ISP pipelines, enabling all important image quality factors (KPIs) to be predicted. It includes a large set of ISP processing blocks that can be applied in arbitrary order.

Introducing Simatest

Henry Koren — Sun, 02 Feb 2025 07:00:00 +0000

A short introduction to Simatest, the camera and image signal processing (ISP) simulator in Imatest. Simatest starts from a raw or simulated image, applies simulated blur (MTF) and sensor noise, and runs it through an ISP pipeline built from blocks such as demosaicing, white balance, color correction, gamma, tone mapping, noise filtering and sharpening, in any order. The result can be analyzed with the same Imatest modules used on real cameras.

The video shows how Simatest lets you model complex ISP pipelines and measure the key image quality metrics they produce, with an example that compares measured and simulated noise and Edge/MTF results for a Panasonic Lumix LX5.

Simatest is part of Imatest 25.1 and later.

Imatest Low Light Illuminance Sensor

Henry Koren — Wed, 13 Nov 2024 23:04:23 +0000

A hands-on demonstration of the Imatest Low Light Illuminance Sensor. The sensor connects to its readout over Bluetooth and reports illuminance in lux, shown live on the readout, in the phone app (with a running graph of the measurement) and in the PC software.

See the Imatest Low Light Illuminance Sensor for specifications and ordering, and the Imatest Spectral Illuminance Color Sensor for color temperature and spectrum.

The Imatest Spectral Sensor app is available for for iPhone, iPad, MacOS and Android.

SFR-Fit CMS Measurement Example

Henry Koren — Mon, 07 Oct 2024 03:22:51 +0000

A measurement example with the Calibrated Reference Camera for Camera Monitor System (CMS) testing with Leader SFR-Fit. The video follows a complete MTF measurement of a CMS electronic mirror in SFR-Fit: entering the CMS monitor parameters, adjusting the reference camera’s exposure and focus on the display, capturing the edge and bar chart images, and reading the resulting MTF curve and measurement table.

See the product page for what is included and how the measurement works, and Automotive Solutions for more.

Imatest Spectral Illuminance Color Sensor

Henry Koren — Mon, 26 Aug 2024 18:20:13 +0000

A demonstration of the Imatest Spectral Illuminance Color Sensor. The sensor measures the spectrum of a light source; its analyzer software shows the spectral power distribution, illuminance, color temperature and chromaticity live as different lights are measured. The video ends with automating the sensor from your own scripts using Imatest Hardware Control and its Python examples.

See the product page for specifications and ordering, and the Imatest Low Light Illuminance Sensor for low light measurements.

The Imatest Spectral Sensor app is available for for iPhone, iPad, MacOS and Android.
