三星 Galaxy S24 Ultra 在 DXOMARK Camera 测试中表现出色，在主摄像头 2 亿像素图像传感器、一系列新的 AI 功能以及最新的骁龙 8 Gen 3 芯片的一臂之力下，整体性能比其前身 S23 Ultra 略有改善。我们的测试人员特别喜欢该三星手机在高光下拍摄的人像照片，色彩鲜艳自然，某些照片感觉比苹果 iPhone 15 Pro Max 更加真实。我们很难说人工智能到底对图像质量做出了多大程度的贡献，但可以肯定的是，新的人工智能工具和三星现有的成像技术极大地改善了某些图像的呈现。
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。
S24 Ultra 得益于新的 HDR 格式和三星成像的结合，在曝光类别中表现非常出色。与上一代 S 系列相比，我们的测试人员可以观察到该手机在多个方面都有显着的改进。在 HDR 屏幕上观看时，HDR 格式可以在亮部和拍摄对象之间产生更自然的对比度。S24 Ultra 得益于三星的图像调整，曝光表现与我们之前测试的 iPhone 15 Pro Max 非常相似。但在一些棘手的条件下，该设备出现了一些轻微的面部曝光问题，而且表现不如 iPhone 15 Pro Max 等一些竞品，因为在连拍一系列图像时，色调映射存在轻微的不稳定问题。
Autofocus irregularity and speed: 1000Lux Δ4EV Daylight 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 1000Lux with Daylight 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.
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.
在高光下，S24 Ultra 图像噪点得到了相当好的控制，但在典型的室内照明下，图像噪点变得相当明显，表现不如 iPhone 15 Pro Max 等竞品，有时甚至落后于其前身 S23 Ultra。在低光条件下，S24 Ultra 的表现更接近竞品的水平，尤其是手持拍摄时。
三星 Galaxy S24 Ultra 在视频变焦方面表现非常出色，与 iPhone 15 Pro Max 旗鼓相当。捏合变焦稳定且相当流畅，视频中没有任何卡顿现象，曝光也相当稳定。不足的是，从一个摄像头模块切换到另一个摄像头模块时，白平衡转换非常明显。由于该三星手机总共配备了四个模块，因此这个问题比摄像头模块较少的设备更大，但整体的拍摄体验仍然宜人。
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.

三星 Galaxy S24 Ultra 在高光条件下呈现出漂亮、自然的视频细节，锐度略低于 S23 Ultra。转向较暗的场景时，经常可以观察到细节不足的问题，只有一些边缘仍然清晰，但脸部则失去了很多皮肤纹理和主要特征。整体细节表现接近 S23 Ultra，但在大多数情况下无法与 iPhone 15 Pro Max 相提并论。

评鉴伪像时，我们使用 MTF，并测量实验室中的 SFR 图表上的振铃，我们也使用 LED 通用计时器进行帧率测量。对自然视频进行视觉评鉴时，我们特别注意混叠、量化、块状和色相偏移等伪像。伪像越严重，越频繁，所扣分数就越多。下面列出主要的伪像和相应的扣分。
Main video artifacts penalties
这款最新的 Galaxy S 系列设备总体上很好地控制了视频伪像，几乎没有任何伪像影响了用户体验。然而，该摄像头拍摄的高对比度和饱和色彩有时可能会导致画面明亮元素周围以及面部出现明显的色相偏移。在低光下录制时，移动的被摄体上会出现一些重影，与之前的 S 系列机型几乎相同，但这些问题在 iPhone 15 Pro Max 上控制得比较好。
三星 Galaxy S24 Ultra 能够提供自适应帧率，在高光和室内使用 60fps，与 iPhone 15 Pro Max 相当，因此在我们的测试中，感知的运动非常流畅。在低光条件下，帧率降至 30 fps，以便在较暗的光照条件下获得良好的整体质量。
