To begin measuring image quality factors with Imatest software, it is important to set up a controlled lab environment with proper charts and lighting, tailored to the system you are testing.

Before performing image quality testing, consider your unique requirements and lab environment variables including imaging system alignment, test/focusing distance, camera support, lighting, and chart selection/mounting.

Even, glare-free illumination is essential for achieving accurate, repeatable measurements. Learn about the most important factors to consider when selecting proper lighting for your image quality testing requirements.

mage quality test charts should be mounted on a smooth flat surface, like an acrylic board, to ensure no blemishes, bends, or bubbles occur that negatively impact image quality measurements. Imatest offers the option to professionally mount our test charts on acrylic or E-panel.

Lenses with normal, wide, ultra-wide, and narrow fields-of-view will determine the charts and equipment you need to properly test your camera systems.

The design, size, and substrate of your test charts are determined by the resolution of your sensor, field of view and working distances of your lens, and the image quality factors you need to test.

Learn how to use our Imatest Master software.

The highest quality images are created by optimizing many key image quality factors. Sharpness determines the amount of detail an imaging system can reproduce. Learn how to optimize sharpness in your camera system using Imatest.

The highest quality images are created by optimizing many key image quality factors. Noise is an undesirable random spatial variation, visible as grain in film, or pixel level fluctuation in digital images. Learn how Noise effects your camera system using Imatest.

Lateral chromatic aberration (LCA), AKA lateral chromatic displacement (LCD) and "color fringing", is a lens aberration that causes colors to focus at different distances from the image center. It is most visible near the corners of images. In this video, we will explain the techniques used to measure for LCA.

Learn the basics of testing color accuracy, including how to process RAW images, measurement techniques, and how to encode color for human perception.

The highest quality images are produced by optimizing many key factors. Dynamic Range is characterized by the ratio between the highest light intensity that a camera system can capture and the darkest tones that become indistinguishable from noise. Dynamic range measurements are useful for optimizing system performance and for verifying camera design specifications. Informed consumers seek camera systems with superior dynamic range, which can capture information in dark shadows while maintaining detail in brighter areas.

ISO Sensitivity (or ISO speed) is a measure of how strongly an image sensor and/or camera responds to light. The higher the sensitivity, the less light (smaller aperture and/or shorter exposure time) required to capture a good quality image.

Lens shading, Light falloff & Vignetting: Where your image becomes darker the further you get from the center. This is due to the radial nature of the lens which collects more light in the center. It can be particularly strong with wide angle lenses. Non-uniformity is also caused by the chief ray angle of light incident to the sensor which has reduced quantum efficiency as the angle increases.

Lens (optical) distortion is an aberration that causes straight lines to curve near the edges of images. It can be troublesome for architectural photography and photogrammetry (measurements derived from images).

The VCX WebCam Studio is a comprehensive target designed to measure a variety of Image Quality Factors. This target is designed according to VCX Webcam standard specifications. The chart contains the Calibrite Classic ColorChecker, Siemens star, spilled coins/dead leaves texture, and slanted edge targets. The VCX webcam studio optionally includes motorized head turner and two different mannequin heads—one with a dark skin tone (Richard) and a second with a light skin tone (Alexis), which are used to compare the behavior of auto white balance (AWB) and auto exposure (AE) algorithms under various conditions. The rotary head turner can turn the head to look away from the camera for testing of adaptive auto-exposure in video webcams. Optionally includes Camera Timing System LED-Panel for timing testing and/or a Specbos spectraradiometer for measuring the lighting spectrum.

Overview of the powerful capabilities of Imatest Industrial Testing Edition. Using Imatest’s algorithms, Imatest IT generates rigorous and repeatable image quality results for manufacturing and quality control.

The ISO 12233:2014-compliant eSFR ISO test chart enables calculation of a number of image quality factors, including but not limited to spatial frequency response, chromatic aberration, tonal response, gamma, white balance and color reproduction.

The key differences between SFRplus and eSFR ISO are outlined. These charts share many similar features and can be used to perform many similar image quality analyses. Understanding which features differ will help you select the most appropriate test chart to analyze your imaging systems.

The elements of the SFRplus test chart enable calculation of a number of image quality factors, including but not limited to spatial frequency response, geometric distortion, tilt, chromatic aberration, tonal response, gamma, white balance and color reproduction.

Imatest SFRreg performs highly automated measurements of sharpness and lateral chromatic aberration from images that contain registration mark patterns: circles with two light and two dark quadrants. Unlike standard test charts, these patterns do not need to be located on a flat surface.

Imatest can estimate an imaging system’s loss of resolution (point spread function) using a pair of collocated, near-sagittal and tangential slanted edges on SFRplus, eSFR ISO and SFRreg targets. Easily analyze and improve sharpness, chromatic aberration, and distortion measurements.

Understanding the performance of an imaging system at its operational working distance is crucial, but testing these systems at long distances isn’t always practical, especially in a production environment. Relay lenses can be used to effectively simulate longer test distances ranging from several meters to infinity. The Imatest Collimator Fixture (ICF) incorporates a relay lens and a test chart along with high precision motorized stages for automated positioning of your camera and target. To validate this lens formula and the fixture itself, we compare the MTF values from real-world images with those from the collimator fixture.

The WFOV Module is an add-on to Imatest’s Modular Test Stand and provides an easy-to use-platform for sharpness testing of wide FOV camera systems up to 200º. The fixture integrates with the Kino Flo LED Freestyle 31 lights. Here we walk you through how to implement this system in your lab setting. Learn More
