摩托罗拉 Edge 40 Pro 在我们图像质量测试的大部分领域都表现出色。拍摄静止图像时，被摄体曝光和白平衡在大多数测试条件下都很好，尤其是在低光下和夜间拍摄时。该摄像头的自动对焦在高光下可以快速准确地工作，通常也会产生良好的纹理/噪点折衷。但是，我们的测试人员在棘手的高对比度场景中可以观察到一些对比度问题，此问题可能会导致剪切和色调压缩。
在视频方面，摩托罗拉 Edge 40 Pro 的排名低于同类中表现最好的设备，用户通常可以在相当静态的场景中录制高质量的视频影片。视频片段呈现准确的曝光和白平衡，细节尚可（但有一些轻微的过度锐化）。在相当静态的场景中，时域噪点得到了很好的控制。在录制过程中移动时，视频防抖并不总是有效，导致摄像头抖动比此类别中的最佳设备明显许多。
关于DXOMARK摄像头测试：在 DXOMARK 进行 Camera 评鉴时，我们在实验室和现实生活情境中拍摄各种各样的主题，然后根据客观测试和感知测试来进行评分。进行客观测试时，我们使用实验室环境中的测量软件直接计算测试结果；感知测试则是由一群图像专家根据一套复杂的度量标准，就需要人为判断的图像质量进行各个方面的比较。智能手机测试需要一个由工程师和技术员组成的团队进行大约一周的测试。他们分别对照片、变焦和视频质量进行评分，然后将这些分数合并为总分，以便在不同手机的摄像头之间进行比较。关于DXOMARK摄像头基准的更多信息，请点击这里。关于智能手机摄像头得分的更多细节，请点击这里。以下部分集合了我们在DXOMARK实验室进行的详尽测试和分析的主要内容。根据需求，我们可以提供更详细的性能评估报告。您可以与我们联系。
Edge 40 Pro 在拍摄静止图像时总体表现不错。在我们的测试中，该设备在照片模式下的主要优势在于能够在各种条件下（包括低光）拍出相当自然的白平衡。它的整体曝光相当准确，但在逆光场景和对比度强的场景中，曝光会有些不准确，并且还出现了一些对比度问题。该摄像头成功地在图像细节和降噪之间保持良好的平衡，从而产生良好的细节水平。美中不足的是，我们的测试人员观察到一些不雅的图像伪像，包括色彩量化和融合伪像。自动对焦通常是准确的，但在大多数情况下速度较慢。
在我们的测试中，Edge 40 Pro 的自动对焦呈现了很多光线，但也有一些暗部。它在对焦被摄体方面表现得很好，只有很少的自动对焦失败。然而，在按下快门按钮和拍摄图像之间存在明显的延迟，这意味着在移动场景中很容易错过决定性的瞬间。
Autofocus irregularity and speed: 100Lux Δ7EV TL84 Handheld
This graph illustrates focus accuracy and speed and also zero shutter lag capability by showing the edge acutance versus the shooting time measured on the AFHDR setup on a series of pictures. All pictures were taken at 100Lux with TL84 illuminant, 500ms after the defocus. On this scenario, the backlit panels in the scene are set up to simulate a fairly high dynamic range: the luminance ratio between the brightest point and a 18% reflective gray patch is 7, which we denote by a Exposure Value difference of 7. The edge acutance is measured on the four edges of the Dead Leaves chart, and the shooting time is measured on the LED Universal Timer.
在此示例场景中，摄像头在模特从画面右侧的墙壁经过时被触发。在生成的图像中，我们可以看到图像的拍摄略有延迟，模特已经离摄像头更近了一步。这种延迟并未出现在诸如荣耀 Magic5 Pro、苹果 iPhone 14 Pro 或谷歌 Pixel 7 Pro 等同类产品中，这些手机都几乎可以立即拍摄照片。
DXOMARK CHART (DMC) detail preservation score vs lux levels for tripod and handheld conditions
This graph shows the evolution of the DMC detail preservation score with the level of lux, for two holding conditions. DMC detail preservation score is derived from an AI-based metric trained to evaluate texture and details rendering on a selection of crops of our DXOMARK chart.
在噪点测试中，我们分析在现实生活中和在实验室图片上拍摄的图像噪点的各种属性，例如强度、色度、颗粒和结构。就自然图像而言，我们特别注意面部、风景以及阴暗区域和高动态范围条件下的噪点。我们也会评鉴自然图像中的运动物体上的噪点。我们在 1 到 1000 勒克斯之间的各种照明条件以及不同类型的动态范围条件下对着图片进行拍摄，并对所拍摄的图像进行客观测量。我们使用枯叶图并进行标准化的测量，例如源自 ISO 15739 的视觉噪点。
在低光下，在实验室中测得的噪点水平与比较设备相似，但在高光下和典型的室内照明条件下则噪点略多。
Visual noise evolution with illuminance levels in handheld condition
This graph shows the evolution of visual noise metric with the level of lux in handheld condition. The visual noise metric is the mean of visual noise measurement on all patches of the Dead Leaves chart in the AFHDR setup. DXOMARK visual noise measurement is derived from ISO15739 standard.
DXOMARK CHART (DMC) detail preservation score per focal length
This graph shows the evolution of the DMC detail preservation score with respect to the full-frame equivalent focal length for different light conditions. The x-axis represents the equivalent focal length measured for each corresponding shooting distance and the y-axis represents the maximum details preservation metric score: higher value means better quality. Large dots correspond to zoom ratio available in the user interface of the camera application.

如果 Edge 40 Pro 还有一些需要改进的地方，那就是远摄变焦。在我们的测试中，该摄像头在几乎整个远摄变焦范围内都拍出了较少的细节。1200 万像素传感器与（相对较短的）50 毫米远摄镜头相结合，无法提供我们在最佳同类设备上看到的纹理和细节，尤其是在中远距远摄变焦时。

在光线充足的情况下，Edge 40 Pro 在视频模式下可以摄入丰富的细节，但是，在棘手的光线条件和低光下可以观察到轻微的细节损失。我们的测试人员还注意到一些轻微的过度锐化，移动元素上的纹理完整性伪像也会偶尔造成场景的整体呈现不自然。
