These scores, trusted by the industry, are backed up by exhaustive protocols that gather hundreds of measurements run in DXOMARK’s state-of-the-art laboratories. With DXOMARK you can display the cameras with three different views - Grid, List or Graph in order for you to have the best solution to compare the filtered results.

根据 DXO 的测试结果可以看到 索尼相机在10bit RAW格式下可以输出15档动态范围。 一般来说相机的动态范围在14-15档左右被认为是比较高的水平。 具体到dB值，可能会有所差异，但通常会超过100dB。 可见采用使用raw图的像素code值，导入动态范围公式计算出来dB并不能准确体现图像传感器的动态范围水平。 人眼动态范围怎么测试的？ 人眼视觉的动态范围指的是人眼所能感知到的最暗和最亮光线的比值。 测试办法： 最小可觉差法: 逐渐降低光源亮度，直到受试者无法感 …

Dynamic range corresponds to the ratio between the highest brightness a camera can capture (saturation) and the lowest brightness it can capture (which is typically when noise becomes more important than the signal — that is, a signal-to-noise ratio below 0 dB). A value of 12 EV is excellent, with differences below 0.5 EV usually not noticeable.

The range of luminance values between the darkest and brightest perceptible points in an image. DXOMARK encourages its readers to share comments on the articles. To read or post …

2023年7月13日 · Derived from DxOMark data using Photographic Dynamic Range (PDR) criteria. Measured Photographic Dynamic Range (PDR) is available for many cameras and is generally preferred when available. Note that the x-axis is ISO Setting and not a "measured" value. Keep this in mind particularly when comparing to the Ideal lines.

Meet the demands of high-performance imaging with 170 dB Dynamic Range, designed for rigorous, repeatable testing in advanced sensor applications like autonomous vehicles.

下面的数据对比完全按照DXO的标准，分成信噪比SNR 18%，动态范围Dynamic Range，色阶范围Tonal Range，以及色彩准确性Coloe Sensitivity四项，每项都按DXO的方法计算像素增益。
