An uprated camera is equipped with a 1-inch Megapixel sensor capable of shooting 4K/60Fps video and burst mode stills at 14 fps. The adoption of Titanium alloy and magnesium alloy construction increases the rigidity of the Airframe and reduces weight, making the Phantom 4 Pro similar in weight to the Phantom 4. The Flight Autonomy system adds dual rear vision sensors and infrared sensing systems for a total of five-directions of obstacle sensing and four-directions of obstacle avoidance.
The onboard camera has been redesigned to use a 1-inch 20-megapixel CMOS sensor. A custom engineered lens made up of eight elements is arranged in seven groups, it is the first DJI camera to use a mechanical shutter, eliminating rolling shutter distortion which can occur when taking images of fast moving subjects or when flying at high speed. In effect, it is as powerful as many traditional ground cameras. More powerful video processing supports H.264 4K videos at 60fps or H.265 4K at 30fps, both with a 100Mbps bitrate. Advanced sensors and processors ensure everything is captured with more image detail and the image data needed for advanced post-production.
Sensor size is more important to image quality than the number of pixels because a larger sensor captures more information in every pixel, improving dynamic range, signal-to-noise ratio, and low light performance. The 1-inch 20-megapixel CMOS sensor in the Phantom 4 Pro is almost four times the size of the Phantom 4's 1/2.3in sensor. It uses larger pixels and has a maximum ISO of 12800 as well as increased contrast. It is good enough for images to be used immediately, while also capturing enough detail for advanced post-processing.
The resolution and contrast of a lens is critical to image quality, because only a quality lens can capture sharp, vivid photos at high resolutions. The brand new Phantom 4 Pro camera has an aerial optimized F2.8 wide-angle lens with a 24mm equivalent focal length. It features eight elements – 2 aspherical – arranged in seven groups that fit into a smaller, more compact frame. Its images are consistently detailed with low distortion and low dispersion, ensuring that photos and videos are sharp and vivid. For the first time ever with a DJI camera, MTF (Modulation Transfer Function) results have been made public, so people can get a better understanding of lens performance.
Aerial imaging is not only used to capture landscapes; it brings new perspectives to everything from action scenes to motor racing. Capturing objects moving at high speed has always been a challenge for flying cameras using an electronic shutter. This is why the Phantom 4 Pro is the first DJI Phantom to use a mechanical shutter and a large-aperture prime lens. A mechanical shutter with a max speed of 1/2000s eliminates rolling shutter distortion which can occur when taking images of fast moving subjects or when flying at high speed. The electronic shutter has also been improved with a max shutter speed of 1/8000 seconds, and a new Burst Mode shoot capable of shooting 14 fps at 20 megapixels to catch the perfect moment.
FlightAutonomy is expanded with an additional set of high-resolution stereo vision sensors placed at the rear in addition to the pair placed at the front as well as infrared sensing systems placed on the left and right sides. This network creates a total of 5-direction of obstacle sensing and 4-direction of obstacle avoidance, protecting the Phantom 4 Pro from more obstacles and giving filmmakers the confidence to capture more complex images.
Three sets of dual vision sensors form a 6-camera navigation system that works constantly to calculate the relative speed and distance between the aircraft and an object. Using this network of forward, rearward and downward vision sensors, the Phantom 4 Pro is able to hover precisely in places without GPS when taking off indoors, or on balconies, or even when flying through windows with minimal pilot control. In the unlikely event that front and downward sensors are unable to operate, the aircraft can still hover in place using the rear stereo vision system. The Phantom 4 Pro also is able to fly in complex environments at a flight speed of up to 31mph (50kph) while avoiding obstacles in its path. In Narrow Sensing Mode, the Phantom 4 Pro narrows its sensing scope enabling it to see in more detail and fly through small spaces.
The Phantom 4 Pro is the first DJI aircraft to use an infrared sensing system. Placed on the left, and right sides of the aircraft, these measure the distance between the aircraft and any obstacles using infrared 3D scanning. When in Beginner Mode and Tripod Mode, these sensors have a horizontal field of view of 70° and a vertical field of view of 20°, providing a wide view of the scene to the sides of the Phantom, and a maximum range of 23ft (7m). Traditional ultrasonic sensors only have a detection range of 3-5m and may be confused when affected by propeller vibration. The infrared sensing system is able to sense larger areas and measure the distance between the aircraft, identifying the closest objects accurately while avoiding interference, providing more reliable sensing and protection.
A 5.5in 1080p screen integrated with the Phantom 4 Pro + offers 1000 cd/m2 of brightness, more than twice as bright as conventional smart devices. As the DJI GO app is built into the screen, hardware and software can be fully optimized, allowing you to edit and share instantly. A five-hour battery life makes the Phantom 4 Pro + a complete aerial imaging solution. The integrated upgraded Lightbridge HD video transmission system supports dual frequencies for greater interference resistance and a maximum video transmission range of 4.3mi (7km)*.
Intelligent Flight - Draw
Draw is a brand new technology for waypoint control. Simply draw a route on screen and the Phantom 4 Pro will move in that direction while keeping its altitude locked. This allows the pilot to focus on camera control and enables more complex shots. There are two Draw modes that can be used in different scenarios.
The Phantom 4 Pro automatically recognizes subjects, follows and captures them as they move, making it easier to get complex shots. Following fast-moving objects can be very challenging, but advanced image recognition algorithms used by the Phantom 4 Pro allow it to recognize and track the object while keeping it in frame. This new algorithm also recognizes more subjects, from people to vehicles to animals, and will adjust its flight dynamics to match, ensuring smoother shots.
