Key Features of the Product
A 3-axis-stablized gimbal camera is boasted by the Phantom 4Pro which comes from DJI. This drone has a 20MP camera which has the capability of taking shots up till 4K/60fps video with the help of 1" CMOS sensor. The photo captured by its camera bursts till 14 fps. The hull is upgraded from the last version of Phantom 4 and now features magnesium alloy that is constructed to increase the rigidity and reduce the weight. The Flight Autonomy method has added a sensor that is dual rear-vision in addition to the infrared sensing. This allows obstacle sensing in nearly 5 directions and the avoidance of the same in 4 directions.
Gimbal Camera that comes with a 1" CMOS Sensor – An onboard camera has been featured for the first time in Phantom line: it has 1-inch 20-megapixel CMOS sensor and a lens which is custom-engineered and made up of 8 elements that are arranged to settle in 7 groups. A mechanical aperture is boasted by the camera which eliminates the distortion of the rolling shutter occurred at the time of capturing the images of fast moving images or when the drone is flying at a very high speed and has a good mechanical focus.
1 inch CMOS Sensor- For the better image quality, the size of the sensor is often taken as an important factor and not the number of pixels. The reason behind this is very simple as a larger sensor comes with a better signal-to-noise ratio, dynamic range and a boosted low light performance. The 1" 20MP CMOS sensor fitted inside the Phantom 4 Pro is 4 times the size of Phantom 4's 1/2.3" sensor. The sensor here uses high pixel range and therefore provides a maximum ISO till 12,800 and increased contrast.
H.264 and H.265 4K Video Recording - The making of a powerful video aids H.264 4K videos at 60 fps or H.265 4K at 30 fps. Both of these are recorded in a 100 Mbps bitrate. The high processors and sensors are capable of making sure that each and everything gets captured and carries almost every detail of the image.
Production-Optimized 4K- The enhanced way of video processing makes it more easy to capture the videos in cinema- and production- optimized DCI 4K (4096 x 2160) at 60 fps with a bitrate of 100 Mbps. H.265 video codec at 30 fps in 4K resolution is also supported by the Phantom 4 Pro. For any bitrate, H.265 has the ability to double the amount of processing of image as H.264. This processing results in significantly enhancing the quality of the image from an extra efficient compression. In order to make the most of the image data for the grading of color, it should be recorded in the high dynamic range D-log mode.
High-Resolution Lens - The camera of Phantom 4 Pro comes aerial-optimized with a wide angle lens of f/2.8 and 24 mm equivalent focal length. 8 elements are featured under it with 2 aspherical that are arranged in 7 groups. All fit into smaller and a more compact frame.
Mechanical Shutter – The act of capturing the images has been a difficult task when the camera is in the air at the time of flight. Therefore, this drone takes the help of a mechanical shutter and a prime lens with large aperture. With the lowest mechanical shutter speed which is 1/2000 second, it eliminates Jello-effect and motion blur that come as a result of shooting with an electronic rolling shutter. You can improve the effect by using the highest speed of electronic shutter that is 1/8000 second. The burst mode with the power of shooting at 14 fps at 20 megapixels allows catching the perfect shot.
Remote Controller with Lightbridge HD Video Link - The controller of Phantom 4 Remote comprises of combined controller that has an upgraded system of Lightbridge HD video transmission which comes added with the support of 5.8 GHz transmission. The power to pick between 5.8 GHz and 2.4 GHz helps the pilots to get pass the interference and remove the lag in the image that is caused while flying the drone in an area having extensive use of 2.4 GHz frequency. In general, the 2.4 GHz frequency is used by the Wi-Fi video transmission systems that work with the help of a controller using a 5.8 GHz frequency.
Lightbridge HD Video Link - The method of Lightbridge HD video transmission used in Phantom 4 Pro takes the help of TDM (Time Division Multiplexing) to send the signals, thus, allowing it to send the controller signals and get signals of video transmission at the same frequency. Since the 2.4 GHz frequency band gets affected by many factors, therefore, 5.8 GHz band is used as it enhances the reliability of transmission. When it is turned on, the level of the local signal gets evaluated and the transmission frequency that has the lowest level of interference gets chosen automatically.
