This new 24-patch Transmissive Color target can be used for evaluating color accuracy using a lightbox, which can be more compact and uniform than a reflective lighting system.
These targets are produced with high-precision Light-Valve Technology. (more…)
Imatest is pleased to announce our partnership with isMedia, a specialist in building digital imaging test machines and custom test solutions. This partnership will provide customers with a wide range of highly customizable test machines capable of extensive image quality analysis on manufacturing lines.
The Sinusoidal Siemens Star test chart allows you to measure MTF and limiting resolution with a chart that provides angular response and may be less affected by signal processing (especially sharpening) than slanted-edges. Siemens star MTF20 (the spatial frequency where MTF is 20% of its low frequency value) is a good estimate of limiting resolution. (more…)
We are pleased to announce our new High Dynamic Range (HDR) test chart with a density range exceeding 120dB (optical density >6.0). This chart allows you to the measure the dynamic range, tonal response and noise of HDR cameras with a single image instead of multiple, exposure bracketed images. It also contains slanted edges for MTF measurements. (more…)
Imatest has several two-dimensional displays for comparing test chart reference (ideal) colors with measured (camera) colors, where reference colors are represented by squares and measured values are represented by circles. (more…)
Imatest has released Version 4.2. New features include:
SFRreg Module: Analyze a camera’s Spatial Frequency Response (sharpness) using automatically-detected slanted edges in registration mark patterns, which can be arbitrarily placed in a camera’s field of view. (more…)
Imatest version 4.2 is now available as a public beta. Join our Beta Test Group to access 4.2 updates. Highlights include:
- Point Spread Function (PSF): Imatest can now estimate an imaging system’s loss of resolution (PSF) 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. (more…)
