Texture & Acutance
One of the most important, and visible, measurements of image quality is the ability to accurately capture texture and edges. The Photo Module provides software and charts that provide Texture MTF and acutance, as well as Edge MTF and Acutance. Texture is measured using the provided reflective "dead leaves" chart that is IEEE-CPIQ compliant.

Tone curve
By varying the illumination, the Photo Module provides a complete picture of the tonal response of your device. This is an excellent way to benchmark both the linearity of sensor response and gamma of the encoded JPEG.

Dead / hot pixels (Raw)
The Photo Module identifies both dead and hot pixels found in Raw image captures, so that you can gather quality statistics or map them out as needed.

Color Sensitivity
By extending the notion of dynamic range to color, DxO Analyzer provides a measure of the color sensitivity of a sensor by calculating the total number of colors it can distinguish, subject to noise. The value is reported out as the number of bits required to encode all those colors.

Noise & Contrast
One of the most important, and visible, measurements of image quality is the ability to accurately capture texture and edges. The Photo Module provides soft and graphics formaware and charts that provide Texture MTF and acutance, as well as Edge MTF and Acutance. Texture is measured using the provided reflective "dead leaves" chart that is IEEE-CPIQ compliant.

Unique to DxO Analyzer is specialized HDR testing hardware that provides accurate contrast measurements ? including tonal ranges and tone curves ? up to 120dB (1,000,000:1) for testing your device’s extended-dynamic-range capabilities. All individual density patches of our HDR chart are uniform, so no defocusing is required to get accurate results. ISO sensitivity can also be measured according to ISO standard #12232.

Row / Column noise
Stripe noise, either in rows or columns, is much more visible than random noise, so controlling it is very important in achieving an effective camera design. DxO Analyzer measures both row and column noise by performing frequency analysis in both dimensions ? charting the results and allowing you to easily spot issues.

ISO Sensitivity (compatible with ISO 12232)
The Photo Module measures and charts actual gain compared to changes in light levels, consistent with ISO standard 12232.

Color
The accuracy of your device's Auto White Balance (AWB) is automatically calculated using DxO's (optional) proprietary closed-loop lighting control system featuring a range of industry-standard illuminants with a standard ColorChecker chart. Once the white balance is calculated, color fidelity and Metamerism Index are also measured. The lighting system also makes it simple to measure color fidelity and sensitivity under a variety of lighting spectrum and illumination levels ? down to just a few Lux.
