Imatest IS Discontinued with Image Acquisition now Available in Imatest Master

As of Imatest 5.0, Imatest Master now features image acquisition capabilities. Previously, image acquisition capabilities were supported by Imatest IS, which has been discontinued as a separate product. This provides all of our customers with access to the acquisition library. The library supports direct acquisition from a wide range of frame grabbers and cameras, as well as industry standard interfaces. Direct image acquisition cuts out several steps in the image quality testing process and allows for in-the-loop testing with Imatest.

Closing the Loop: Distortion Correction

Imatest’s charts and software allow you to measure the characteristics and parameters of imaging systems. Quite often these measurements simply indicate the limits of system performance and expected image quality.

But some Imatest results let you improve image quality— and subsequent images taken by the same system— by correcting measured aberrations. (more…)

Best practices for using transmissive test charts

 

Light Source

Side chart largeThe most uniform light source available would be an integrating sphere, but these come with considerable size and expense. After considering how the light source uniformity impacts their results, most lab & manufacturing tests use LED or fluorescent lightboxes with flat-panel diffusers. (more…)

Testing a macro lens using Checkerboard and Micro Multi-slide

Imatest’s Checkerboard module is our new flagship module for automated analysis of sharpness, distortion and chromatic aberration from a checkerboard (AKA chessboard) pattern. The big benefit of using the checkerboard is that there are looser framing requirements than with other kinds of test targets. While checkerboard lacks the color and tone analysis provided by SFRplus and eSFR ISO, these features are not available on the high precision chrome on glass substrate, so the checkerboard is the optimal pattern for this test.

Using Sharpness to Measure Your Autofocus Consistency

Autofocus plays a major role in many camera system applications with variable focus, including consumer electronic devices. Camera systems must be able to focus at a variety of distances. Optical systems on cameras only allow a certain range of distances from the camera to be in focus at once (this is often known as the depth of field, or depth of focus). (more…)

Imatest Version 4.4

Imatest is pleased to announce the release of version 4.4, which includes the following features:

Support for all 2016 Camera Phone Image Quality (CPIQ) standard metrics for mobile device image quality. CPIQ serves as a way to assess and communicate image quality to the vast majority of consumers who are unsure how to judge and compare device image quality. See a full CPIQ overview.

Auto-focus, Auto White Balance, and Auto Exposure (AAA) metrics for faster image adjustments. AAA metrics were created to address the video image quality aspects that most affect user experience.

Sinusoidal Siemens Star Target

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…)

SFRreg Target

The SFRreg test target consists of a slanted-edge quadrant pattern enclosed within a circle. It is used for measuring MTF and lateral chromatic aberration. A test image typically contains several targets that are automatically detected and analyzed by Imatest 4.2. (more…)

High Dynamic Range Target, ITI LED Lightbox

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…)
