If you use DJI Action 2 to shoot in super slow motion, you can slide left and right in the center of the main interface to select the slow motion mode, click or swipe up the parameters at the bottom, select the required resolution and the corresponding speed change ratio on the slow motion setting parameters page, and then press the video button to start shooting. During the shooting process, you can click the lower right corner to switch the speed of slow motion. After the shooting is completed, you can click the playback button on the left side of the main interface to browse the material. If you use the Pocket Eye Sports Cameras/Eye Sports Cameras/Eye Mobile Platform 3, connect the device to the mobile phone. In the interface of the DJI Mimo App, gently press the "slow motion" button with your finger, swipe right on the camera screen to enter the option, then drag right to the option, and then pull down to select "slow motion". The Eye Sports Cameras can also use 8x slow motion to record related images. Read more exciting novels for free
The motion detection camera algorithm was usually based on the images collected by the camera at different frame rates, and the CPU calculated and compared them according to a certain algorithm. When there was a change in the image, such as someone walking by or the camera being moved, the corresponding operation would be triggered when the calculation result exceeded the predetermined range. Take the Kazuki camera as an example. The image captured by the camera was processed by the CPU algorithm. When the image was different from the image captured a second ago, the system automatically prompted an alarm. If a moving object was detected, the camera would turn on the recording function and push the alarm message to the phone. The PIS motion detection technology was based on the principle that objects above absolute zero emit infrared radiation. When a heat source such as a human body enters the detection range of the PIS sensor, the thermal element in the sensor senses the change in infrared radiation and transforms it into an electrical signal. After amplification, filtering, and comparison processing, it triggers an alarm or recording mechanism. It uses the difference between the current image and the background image to detect moving areas, but it is sensitive to dynamic scene changes such as lighting and external interference. In addition, there was also a motion detection energy-saving method based on the image comparison algorithm disclosed by Zhengyuan Wisdom, which included the steps of activating the motion detection device when the human body or the vehicle body entered the sensing range of the human body proximity sensor, assisting the camera unit to shoot through the lighting unit, transmitting the image to the external host for division, marking, and other operations. Finally, the image in the memory was finally processed by the computing processor using the image comparison algorithm and stored in the memory. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the motion camera is shaky, you can use the following methods to solve it: * * 1. The camera's own anti-shake technology ** 1. * * Image Stabilizer (CCTV)** - The principle was to place the CCDs on a stand that could move up, down, left, and right. First, it detected the shaking situation, including the direction, speed, and movement of the shaking. Then, it processed the detection signal to calculate the amount of movement of the CCD-based camera that could offset the shaking. Then, it used the mechanical movement inside the camera to compensate for the hand shaking to achieve anti-shake. 2. * * Image stabilization ** - It was to offset the vibration by moving the lens horizontally or vertically. The longer the focal length of the lens, the better the anti-shake effect of the lens. In low light conditions, the anti-shake effect of the lens can also perform better because it can be used as an independent working unit without affecting the focus and dimming system of the camera sensor. However, lens anti-shake could only reduce the shaking when shooting with a hand-held camera, but it could not completely eliminate it. It might not be effective or even counterproductive when shooting special scenes such as shooting birds, long exposure, stacking, etc. 3. * * Five-axis anti-shake (Take Oppo as an example)** - It can achieve anti-shake operations such as pitch, swing, horizontal translation, vertical translation, and rotation in a narrow body space. The maximum anti-shake range of horizontal translation and vertical translation can reach +3 °. Technically, it used software algorithms to distribute the split shake data to the two moving components of the lens and sensor, and then used a motor or memory metal to drive the lens or sensor to produce displacement to achieve anti-shake. This anti-shake technology improved the OIS anti-shake ability of conventional lenses by 65%, and the anti-shake accuracy was increased to 3.5 times. When capturing motion images such as skateboarding, it could make the image stable and the details of the character's movements rich. In dark scenes, it could also be used with self-developed algorithms to achieve the ultimate image. * * 2. Borrowing external equipment ** 1. * * Holding the Cloud Platform ** - For example, a hand-held cloud head like the Okugawa Smart XI had a three-axis anti-shake function. It also had the functions of switching between horizontal and vertical screens, remote shooting with gestures, and zooming with silk-smooth focus. Through the mechanical structure and electronic control of the cloud head itself, it stabilized the lens during sports shooting and reduced the lens shake caused by hand-held shaking. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sure. It depends on the medium and the style of the story. In film or video, slow motion is a common technique. In written stories, you can describe events in a way that gives the impression of slow motion through detailed and deliberate pacing of the narrative.
You can use descriptive language to create the effect of slow motion. For example, describe every detail of the action very precisely to make it feel like it's happening in slow motion.
There were some cameras on the market that supported night vision, but there was no explicit mention of whether they supported high-definition video recording. However, according to the development trend of camera technology, cameras now generally had infrared night vision and could record high-definition videos at night. The detailed information about the night vision high-definition camera recording required further investigation and research.
Night vision high-definition video camera was a camera with night vision and could record high-definition video. The following conclusion: There are some cameras on the market that support night vision, but there is no explicit mention of whether they support high-definition recording. However, according to the development trend of camera technology, cameras now generally had infrared night vision and could record high-definition videos at night. For example, Hikvision's 8-million-pel Starlight camera could not only record clearer videos, but also store them faster and save more memory. In addition, there were other brands of cameras that also supported high-definition night vision recording. Therefore, the night vision high-definition camera could record clear videos in the night environment.
