New Delhi,27th June 2023 OPPO is known for innovations in smartphone photography, and now, with its Reno 10 Pro+, it brings its new periscope lens design to the camera module. This setup reduces what could be a thick camera bump to make this device the slimmest and lightest periscope telephoto handset in the industry.
The periscope design creates a 3x optical telephoto setup that delivers beautifully-proportioned portraits with a soft bokeh background. It even compresses distant elements in a scene—like monuments, buildings, and mountains—to bring them closer to your portrait subject for more dramatic snapshots.
Periscope Design Telephoto Portraits
Stacking lens—one over the other—to create optical zoom and/or telephoto lens results in thicker camera bumps on a smartphone. OPPO’s periscope lens is a workaround for this vertical height constraint.
Usually, when light enters the camera, it goes through the lens array straight to the sensor. But with the periscope design, the stacked lens and the sensor are turned sideways. In the Reno 10 Pro+, for instance, the optically-stabilised telephoto lens is offset by 90 degrees to focus light onto the image sensor after it travels through a prism; this results in a telephoto lens module that does not protrude too far out from the phone. The Reno10 Pro+ has a periscope module that is 0.96mm thinner than other devices.
With the OPPO Reno10 Pro+’s 3x telephoto lens, you can shoot portraits from a distance—just like you would with a DSLR—for more natural facial proportions, devoid of any mild fish-eye distortion that you would get from smartphone cameras that force you to shoot from closer. These portraits boast a natural optical bokeh that separates the subject from the background to add depth to photographs.
In outdoor settings, the telephoto lens also compresses the gap between the portrait subject and distant elements in a scene—monuments, buildings, and mountains—to create dramatic but well-composed portraits.
At 64MP, this telephoto portrait camera is the highest megapixel telephoto portrait camera in the industry—backed by a 1/2-inch image sensor—that lets you snap portraits with up to 3x telephoto with OIS; you also get 120x hybrid zoom. The closest focus distance of this camera is 25cm.
In low light, the telephoto lens excels at enhanced light gathering for brighter and clearer portraits with reduced noise while preserving the natural ambience of the scene.
In keeping with its legacy, the Reno 10 Pro and Pro+ pack three other impressive shooters to complement their telephoto cameras.
Their 50MP main snapper comes with the Sony IMX890 sensor and a 1/1.56-inch ultra-large sensor size for high light intake. It also supports OIS and all-pixel omnidirectional focus for added stability and clarity.
When combined with the new colour calculation engine, TurboRAW2.0, the Reno 10 Pro+’s process speed for night-time photography has increased by 54%, the capture success rate of quick snapshots by 7%, and the dynamic range of the photo by 11% for overall accurate colours and richer details when compared to the Reno 8 Pro*.
The Reno 10 Pro and Pro+ also sport the 8MP Sony IMX355, a 112° ultra-wide-angle camera with a 1/4-inch sensor. Its exceptional sensitivity to light produces clear images even in dark environments, while its rapid frame rate of up to 120FPS makes it ideal for shooting fast-moving objects. The IMX355 boasts a broad dynamic range that allows it to preserve details in bright and dark areas of a photograph.
And finally, you get the 32MP Sony IMX709 sensor with AF for selfies and precise facial recognition even in low light. This RGBW sensor on the front camera is customised for OPPO, where the colour W (white) is inserted into each RGGB pixel array; this increases the light intake by 60% when compared to general RGGB lens. It is backed by a 1/2.47-inch sensor and a 90° FOV for wider selfies.
To further enhance image processing, the Reno10 Pro+ packs the Ultra-Clear Imaging Processing Engine—powered by Qualcomm’s Snapdragon 8+ Gen 1 platform—for ultra-clear photos where every detail is preserved with remarkable precision.
Anti-reflective Lens Coating
To ensure that a maximum amount of light reaches the sensor, the camera lens on the Reno 10 Series comes with ALD (atomic layer deposition) coating that prevents green and red glare. This reduces light reflectivity by up to 70% to ensure that unwanted reflections are minimised for clearer and more vibrant images.
Additionally, the spin-coating process is applied to the blue glass to create a uniform thin film with nanoscale thickness. This coating absorbs infrared light and prevents stray light. It further enhances the optical performance to deliver sharper and more precise images while minimising unwanted artefacts caused by stray light.
OPPO AI and NPU
Like all OPPO devices the camera setup on the Reno 10 Series leverages proprietary algorithms, filters, and photo-editing tools for the beautification of portrait images.
Additionally, the Reno 10 Pro+ comes with camera algorithms that kick in for 4K videos to fuse two frames of long- and short-exposure image information in real-time to widen the original dynamic range four times. Simultaneously, the AI Noise Reduction (AINR) algorithm intelligently identifies noise pixels in night-time videos and denoises each frame for noise reduction. Also, the Reno 10 Pro+ utilises an AI Depth algorithm that has undergone extensive training with millions of images. It calculates the distance between objects and characters in the background to create a precise depth map for beautiful bokeh.
It is only after these processes are completed by OPPO algorithms that the data is transferred to the Snapdragon 8+ Gen 1 SoC for exposure and colour adjustments via the independently developed 3A (Autofocus, Autoexposure, Auto white balance) algorithms to result in natural-looking, evenly-exposed videos.
