Release 3.5 includes ISO sensitivity analysis

 

ISO sensitivity (also called ISO speed), is included in Release 3.5 of both Imatest Master and Industrial Testing (IT) packages. ISO sensitivity is a measure of how strongly an image sensor and/or camera responds to light. Both Saturation-based and Standard Output Sensitivity, as described in ISO 12232, are calculated, but the measurement procedure has been considerably streamlined as compared to the ISO specification.

Imatest Partners with ON Semi to Speed CMOS Sensor Configuration

CMOS sensor R&D is enabled by Imatest

There are no shortcuts in the process of CMOS image sensor configuration. There is only a myriad set of tasks: setting sensor registers; capturing images; conducting tests; and analyzing results – a cycle that is repeated again and again to achieve an ideal configuration. From medical devices to mobile-phone cameras to military targeting systems, CMOS image sensors support a diverse range of imaging applications. (more…)

Imatest 3.1 released

Multiple files can be read and averaged (and saved) to facilitate measurements of fixed-pattern noise (in Stepchart, Colorcheck, and Light Falloff) and image stabilization (SFR). Highly distorted regions of interest (ROIs) can be analyzed with Colorcheck and Stepchart. New ΔE measurements and hot/dead pixel options have been added to Light Falloff.

Imatest 1.2 Released

RAW files are supported for a large number of digital cameras using Dave Coffin’s dcraw program. Files are converted with minimal signal processing— no sharpening or noise reduction. This allows the true performance of cameras and the behavior of raw converters to be analyzed.

Chromatic Aberration is now measured as percentage of the distance from the image center. This is an improvement over area in pixels because CA tends to be proportional to that distance. (more…)
