For a device in our High-end segment, the impressive camera performance of the Google Pixel 7 rivaled that of the Ultra-Premium Google Pixel 7 Pro. With both two models having the same primary camera and a nearly the same ultra-wide camera, the major difference in the setup is that the Pixel 7 is not equipped with a tele module like the Pixel 7 Pro. But as our results showed, that didn’t deter from the Pixel 7’s excellent camera experience.

In still images, the Pixel 7 delivered nice skin tones and natural white balance in most test conditions. Target exposure was accurate, with a wide dynamic range and nice contrast, making the Google device a great option for portrait photography. The autofocus was fast and accurate, test images showed high levels of detail, and artifacts were well under control, with only some aliasing noticeable. On the downside, some noise was noticeable in the shadow areas of the frame.

Zoom performance was where the Pixel 7 lagged behind the Pixel 7 Pro, due to the lack of a dedicated tele lens and a narrower field of view on the ultra-wide camera. In video clips, the Pixel 7 delivered good exposure and a wide dynamic range. The autofocus reacted swiftly and kept moving subjects in focus. Detail was good, especially in bright light, and the stabilization did a good job of keeping things steady. However, temporal noise was visible, especially in HDR and low-light scenes.

DXOMARK tests video at the settings that provide the overall best quality. In the case of the Pixel 7, this was  4K resolution at 30 frames per second, with the HDR10+ option disabled.

Test summary

About DXOMARK Camera tests: DXOMARK’s Camera evaluations take place in laboratories and in real-world situations using a wide variety of subjects. The scores rely on objective tests for which the results are calculated directly by measurement software on our laboratory setups, and on perceptual tests in which a sophisticated set of metrics allow a panel of image experts to compare aspects of image quality that require human judgment. Testing a smartphone involves a team of engineers and technicians for about a week. Photo, Zoom, and Video quality are scored separately and then combined into an Overall score for comparison among the cameras in different devices.

About DXOMARK Camera Photo tests

For scoring and analysis, DXOMARK engineers capture and evaluate more than 2,600 test images both in controlled lab environments and in outdoor, indoor and low-light natural scenes, using the camera’s default settings. The photo protocol is designed to take into account the main use cases and is based on typical shooting scenarios, such as portraits, family, and landscape photography. The evaluation is performed by visually inspecting images against a reference of natural scenes, and by running objective measurements on images of charts captured in the lab under different lighting conditions from 1 to 1,000+ lux and color temperatures from 2,300K to 6,500K.

Google Pixel 7 Photo scores

The photo tests analyze image quality attributes such as exposure, color, texture, and noise in various light conditions. Autofocus performances and the presence of artifacts on all images captured in controlled lab conditions and in real-life images are also evaluated. All these attributes have a significant impact on the final quality of the images captured with the tested device and can help to understand the camera’s main strengths and weaknesses.

Highest Score

Exposure and color are the key attributes for technically good pictures. For exposure, the main attribute evaluated is the brightness of the main subject through various use cases such as landscape, portrait, or still life. Other factors evaluated are the contrast and the dynamic range, eg. the ability to render visible details in both bright and dark areas of the image. Repeatability is also important because it demonstrates the camera’s ability to provide the same rendering when shooting several images of the same scene.
For color, the image quality attributes analyzed are skin-tone rendering, white balance, color shading, and repeatability. For color and skin tone rendering, we penalize unnatural colors but we respect a manufacturer’s choice of color signature.

Autofocus tests concentrate on focus accuracy, focus repeatability, shooting time delay, and depth of field. Shooting delay is the difference between the time the user presses the capture button and the time the image is actually taken. It includes focusing speed and the capability of the device to capture images at the right time, what is called ‘zero shutter lag’ capability. Even if a shallow depth of field can be pleasant for a single subject portrait or close-up shot, it can also be a problem in some specific conditions such as group portraits; Both situations are tested. Focus accuracy is also evaluated in all the real-life images taken, from infinity to close-up objects and in low light to outdoor conditions.

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. 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.

Texture

Texture tests analyze the level of details and the texture of subjects in the images taken in the lab as well as in real-life scenarios. For natural shots, particular attention is paid to the level of details in the bright and dark areas of the image. Objective measurements are performed on chart images taken in various lighting conditions from 1 to 1000 lux and different kinds of dynamic range conditions. The charts used are the proprietary DXOMARK chart (DMC) and the Dead Leaves chart.

Noise tests analyze various attributes of noise such as intensity, chromaticity, grain, structure on real-life images as well as images of charts taken in the lab. For natural images, particular attention is paid to the noise on faces, landscapes, but also on dark areas and high dynamic range conditions. Noise on moving objects is also evaluated on natural images. Objective measurements are performed on images of charts taken in various conditions from 1 to 1000 lux and different kinds of dynamic range conditions. The chart used is the Dead Leaves chart and the standardized measurement such as Visual Noise derived from ISO 15739.

Bokeh is tested in one dedicated mode, usually portrait or aperture mode, and analyzed by visually inspecting all the images captured in the lab and in natural conditions. The goal is to reproduce portrait photography comparable to one taken with a DLSR and a wide aperture. The main image quality attributes paid attention to are depth estimation, artifacts, blur gradient, and the shape of the bokeh blur spotlights. Portrait image quality attributes (exposure, color, texture) are also taken into account.

About DXOMARK Camera Zoom tests

DXOMARK engineers capture and evaluate over 400 test images in controlled lab environments and in outdoor, indoor, and low-light natural scenes, using the camera’s default settings and pinch zoom at various zoom factors from ultra wide to very long-range zoom. The evaluation is performed by visually inspecting the images against a reference of natural scenes, and by running objective measurements of chart mages captured in the lab under different conditions from 20 to 1000 lux and color temperatures from 2300K to 6500K.

The Google Pixel 7’s main difference to the Pro version is the lack of a dedicated tele camera. It relies on digital zoom on the primary camera and cropping instead. As a result, Pixel 7 tele zoom images offered lower levels of detail, even at moderate zoom factors. Exposure and color were very similar to the Pro version. The Google Pixel 7 also comes with a slightly narrower ultra-wide module. Overall, the Pixel 7 ultra-wide was close to the 7 Pro, though. Both produced accurate target exposure, autofocus, and a fairly high level of detail. However, the Pixel 7 often showed a slightly stronger white balance cast.
