Google’s Android Image Quality Expert Pursues New Role With Imatest

Imatest is happy to welcome Jonathan Phillips, previous Google Android head of imaging, to the team as Vice President of Imaging. Under Phillips’ technical leadership, Imatest will be expanding its software features, equipment portfolio, and consulting services across imaging market segments. As the previous leader of image quality in Google’s Android organization, Phillips focused on the launch and establishment of Google’s Pixel phone line, particularly its camera and display image quality and features. In addition, Jonathan has an extensive background in image quality with NVIDIA and Kodak, and is a co-author of “Camera Image Quality Benchmarking”.

Such an announcement has grabbed traction among the tech and imaging industry, reaching companies such as BusinessWire and Colorado Photonics. Welcome to the team, Jonathan!

Logarithmic wedges: a superior design

We introduce the logarithmic wedge pattern, which has several advantages over the widely-used hyperbolic wedges found in ISO 12233 (current and older) and eSFR ISO charts. Logarithmic wedges will be available in eSFR ISO charts starting in 2022, and will be supported by Imatest 2021.2+.

The key advantage of logarithmic wedges is that charts with large fmax/fmin ratios work well for systems with a wide range of resolutions, unlike hyperbolic wedges, where large ratios cause high frequencies occupy excessive real estate and low frequencies to become highly compressed. The fmax/fmin ratio of the hyperbolic wedges in the ISO 12233/2017 chart is only 12.5:1 — insufficient for modern high resolution cameras.

Camera to Chart Alignment

Centering test charts is critical for image quality testing. If the camera is not properly aligned with the test chart, your image may not be suitable for analysis; you may not know if the results are truly indicative of the camera system, or from an error in positioning the chart.  (more…)

Long Range Testing with the OSCM10120 Target Projection Collimator

Introducing the CM10120 Collimator – a target projection collimator system that allows users to simulate long-range testing in confined spaces. This compact solution can be used for regional sharpness testing, making it useful for tasks such as setting focus or checking pass/fail criteria. The CM10120 includes adjustable distance simulation and is suitable for R&D, production, and end of line testing. To learn more about the CM10120contact us at sales@imatest.com.

Using images of noise to estimate image processing behavior for image quality evaluation

In the 2021 Electronic Imaging conference (held virtually) we presented a paper that introduced the concept of the noise image, based on the understanding that since noise varies over the image surface, noise itself forms an image, and hence can be measured anywhere, not just in flat patches.

You can download the full paper (in the original PDF format) here.

Real-time focusing with Imatest Master direct data acquisition

Speed up your testing with real-time focusing in Imatest Master 2020.2.

Recent speed improvements allow for real-time focusing and allow users to analyze images from two types of sources:

Although the majority of images traditionally analyzed by Imatest have been from files (JPG, PNG, etc.), three modules, which can perform a majority of Imatest’s analyses, support direct data acquisition, and can be used for realtime analysis.

Image Quality Testing for Webcams

Webcams are an increasingly vital tool for working remotely and staying connected with friends and loved ones. As such, webcam sales have experienced significant growth. We all know good and bad quality images when we see them, but quantifying a camera’s performance is critical for making design choices, sourcing components, and performing quality control. Developing these devices presents challenges common to the development of consumer cameras. (more…)

Correcting Misleading Image Quality Measurements

We discuss several common image quality measurements that are often misinterpreted, so that bad images are falsely interpreted as good, and we describe how to obtain valid measurements.

Describing and Sampling the LED Flicker Signal

High-frequency flickering light sources such as pulse-width modulated LEDs can cause image sensors to record incorrect levels. We describe a model with a loose set of assumptions (encompassing multi-exposure HDR schemes) which can be used to define the Flicker Signal, a continuous function of time based on the phase relationship between the light source and exposure window.

Validation Methods for Geometric Camera Calibration

Camera-based advanced driver-assistance systems (ADAS) require the mapping from image coordinates into world coordinates to be known. The process of computing that mapping is geometric calibration. This paper provides a series of tests that may be used to assess the goodness of the geometric calibration
