最新的 OPPO 旗舰产品是最适合在昏暗条件下拍摄的智能手机之一，类似于其前身 OPPO Find X6 Pro。在我们的测试中，它在显示暗部细节方面表现出色，对比度良好，低光图像的细节良好，噪点非常少，在照片和视频中都是如此，该 OPPO 的噪点水平可与 iPhone 15 Pro Max 相媲美。
Oppo Find X7 Ultra – 动态范围宽广，细节恢复良好，噪点不多
测试摘要
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。
Autofocus irregularity and speed: 100Lux Δ4EV 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 4, which we denote by a Exposure Value difference of 4. 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.
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.
该摄像头得益于大型传感器的聚光能力，通常可以攝入丰富的细节，并能很好地保留精细细节。总体而言，除了 iPhone 15 Pro Max 在高光条件下捕获的 2400 万像素图像之外，Find X7 Ultra较大多数竞品都能更好地保留精细细节，

苹果 iPhone 15 Pro Max - 更大的 2400 万像素输出，因此可以保留非常精细的细节
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。
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.
在 14 毫米等效焦距下，该超广角摄像头的视场比 Find X6 Pro 略宽。然而，该模块使用较小的图像传感器，在我们的测试中，攝入的细节水平与华为 P60 Pro 或 Vivo X100 Pro 等竞品不相上下。尽管如此，总体而言，OPPO Find X7 Ultra 在各种变焦设置下都保持了相当高的图像质量，在中远距远摄时达到顶峰。
Oppo Find X7 Ultra Zoom Scores
This graph illustrates the relative scores for the different zoom ranges evaluated. The abscissa is expressed in 35mm equivalent focal length. Zooming-in scores are displayed on the right and Zooming-out scores on the left.
视频变焦
Oppo Find X7 Ultra 在视频模式下进行变焦拍摄时可拍出丰富的精细细节，而且噪点不多。尽管该手机增加了摄像头模块，但仍然将转换处理得很好，取景变化不大，在曝光和色彩方面也只观察到轻微的变化。但在手机市场上，苹果 iPhone 15 Pro Max 的转换仍然是最流畅的。
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.
