Precise contrast range measurement of digital cameras
be more than three or four patches in saturation. Running the image through the OECF analysis of the iQ-Analyzer you get dynamic range, noise behavior, Signal to noise ratio, ISO speed, and white balancing as a result. Especially for some of the noise...

A day with ‘the movies’: Testing digital cinema-quality cameras
tested the cameras using the TE42v2, a specialized test chart that permits the measurement of resolution, visual noise, dynamic range, texture loss, and many elements of image quality. So, how do we test image quality in ‘moving pictures’? Just as we...

Consumer cameras and their HDR mode - what are they doing?
More and more cameras provide a so-called High Dynamic Range (HDR) mode these days. If the scene that you want to get onto your memory card has a too strong contrast, this mode will help to maintain the shadows while keeping the highlight. Because the...

Is image quality relevant for cameras in ADAS?
classification, a typical task for ADAS. HDR & Noise Common scenarios for an automotive camera tend to have a very high dynamic range, i.e., the difference between the darkest regions and the brightest regions of a scene. A typical example is a car...
