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.

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.

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.

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 slanted-edge method of measuring the spatial frequency response (SFR) as an approximation of the modulation transfer function (MTF) has become a well known and widely used image quality testing method over the last 10 years. This method has been adopted by multiple international standards including ISO and IEEE. Nearly every commercially available image quality testing software includes the slanted-edge method.
