尽管三星 Galaxy Z Fold5 没有在 DXOMARK 摄像头中名列前茅,但它在我们的大多数测试类别中都取得了不错的成绩,并且能够在大多数拍摄条件下拍摄出漂亮的照片和视频片段。Galaxy Z Fold5 摄像头也比其前身 Z Fold4 略有改进。考虑到它们都配备有相同的摄像头硬件,Galaxy Z Fold5 稍微更好的表现应该完全要归功于更好的成像软件和微调。然而,对于用户来说,(仍属)创新的折叠设计和大屏幕无疑是高价位的 Galaxy Z Fold5 最值得注目的地方,但如果摄像头性能是用户的首要考虑因素,那么具有更传统外形的其他高端设备可以提供更好的拍摄效果。

三星 Galaxy Z Fold5 在为朋友和家人拍摄照片和视频时表现相当好。在人像场景中,拍摄对象的曝光度大致良好,即使在棘手的逆光条件下,摄像头也能在拍摄对象上保持良好的对比度。演色性很好,在照片和视频模式下肤色都很自然。散景模式下的图像效果也很自然,非常接近用户对数码单反相机和大光圈镜头的期望。美中不足是,该摄像头无法提供零快门时滞,这意味着它在拍摄运动场景中的决定性时刻时,比同类其他设备相形见绌。此外,它的景深相当窄小,导致集体合影中的后方被摄体失焦。
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。
在照片模式下,三星 Galaxy Z Fold5 在大多数使用情况下都表现良好。测标曝光始终准确,动态范围相当宽广,在高对比度场景中拍摄到良好的亮部和暗部细节。在色彩方面,有时会出现轻微的白平衡色偏,但仍处于可接受的范围内。在大多数情况下,自动对焦稳定而可靠。美中不足是,在所有测试条件下,都可以观察到图像噪点,噪点水平有时在帧的离散区域达到峰值。
Autofocus irregularity and speed: 20Lux Δ7EV Tungsten 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 20Lux with Tungsten 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.
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.
在纹理方面,即使在低光下,Z Fold5 也能产生不错的效果。精细细节保留得很好,仅有轻微的锐化,但 Z Fold5 的纹理性能无法完全与谷歌 Pixel Fold 相提并论。
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.
由于 Z Fold5 在所有光线条件下的噪点水平都很高,在此测试类别中还有一些改进的空间。我们的测试人员还注意到,在所有光照水平下,局部噪点比画面的其他部分还多。
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.
