The Legend of the Dragon King

There were many ways to drive a lens. The following were some common ways to drive a lens: - ** Fuseline-driven AF-lens **: The driving source comes from the body of the AF-DSLR camera. There was a transmission mechanism in the lens that was connected to the manual focusing ring. When the "MG/FA" focusing mode selection lever on the camera body was turned to the "FA" position, the transmission shaft of the FA motor in the camera body extended out to fit with the lens transmission shaft and was driven by the FA motor of the camera body. However, during autofocus, the manual focus ring on the lens would rotate. When using the AF-mode, the focus ring could not be touched, and the mechanical structure of the focus ring was relatively loose. - ** Lens-driven AF-lens **: The body only sends focus signals and power to the lens. All mechanical movements are completed in the lens. There is no mechanical connection between the lens and the body. - ** Automatic Aperture Driving Method **: - ** Video Driver (DV) lens **: The drive circuit board of the aperture motor is installed in the lens. The camera is used to output the image signal to the drive circuit board, and then the drive circuit board changes the aperture motor to change the aperture. However, the cost and construction are relatively expensive. - **Video Drive Automatic Aperture **: Control the lens through three wires. One of them is the video trigger signal to start the aperture and control the size. The other two are the DC12V power wires to drive the motor. - **DCDriver (DD) lens **: Cooperate with some camera manufacturers to transfer the drive circuit board originally installed in the lens to the camera. The lens does not need a drive circuit board. The camera directly changes the aperture motor by the output of the camera's DC-current. The cost of a camera with a DC-drive interface was slightly higher (some circuits were added), but the automatic aperture lens was small and cheap because it did not contain a drive circuit. - ** DC-driven auto-aperture lens **: The lens is controlled by four wires, two of which are DC12V, and the other two control wires control the aperture size by sensing the illumination of the external light source through the light sensing point in the lens. If the camera has two aperture driving modes at the same time, the specific definition of whether it is the DV or the DD driving mode must be set by the switch or the OSD menu. - ** P-Iris **: A new type of automatic and precise lens aperture control. Its main purpose is to set the best aperture position, so that the center and the best part of the lens can be used to improve the image quality. It can reduce optical errors and achieve the best image quality in terms of contrast, resolution, and depth of field. - ** Driving method according to the type of focusing motor **: - ** DC-direct current motor **: Converts direct current electric energy into mechanical energy, low cost and high power. There were two ways to use lens products. One was to directly drive a large-volume focusing lens group (commonly used in medium-frame and super-large aperture lenses), but the movement was large. The other was to minimize and mute it for low-end products to control costs. However, the focusing speed was not fast. - ** ultrasonic motor and its variants **: Commonly used for mid to high-end single-lens reflex lenses. The lens was driven by converting ultrasonic vibrations into kinetic energy. It had the characteristics of fast focusing, quietness, and full-time manual focusing. The ring-shaped ultrasonic motor was powerful and quiet. The compact ultrasonic motor was used for low-end or compact products. However, in terms of video shooting, due to the excessive inertia, it did not perform well when changing the driving direction frequently or moving slowly (but Canon's NANO USM motor had been improved). - ** Stellar Stepping Drive **: With the rise of video creation, the motor rotation can be controlled according to the increase or decrease of the pulse signal, and the start and stop response is good. Compared to the ultrasonic motor, it was quiet, small, had little inertia, and fast response. It could meet the needs of video shooting. It was divided into lead screw type and compact gear type. - ** Voice coil motor **: The principle is to control the stretching position of the spring by changing the magnitude of the direct current in the coil of the motor in the permanent magnetic field, thus driving the up and down movement. It has the characteristics of high speed and high precision. It is also widely used in the field of mobile phone lenses. It has strong driving force, fast speed, silence, and fast response. It is suitable for driving large-caliber focusing lenses and also suitable for video focus tracking. - ** Driving method of specific lens **: - In some electronic devices, when the lens and the driving part are used for optical image stabilization, the rows of the pixels in the second image frame can be determined according to the image area in the first image frame, the output timing of the rows of the pixels can be determined according to the exposure timing of the second image frame, and the driving part can be controlled to drive the lens to perform optical image stabilization and move it to the initial position at the corresponding timing. - Some lens components could achieve the integration of the driving components and the lens by connecting part of the lens to the shell and other structures, thus simplify the sealing design of the lens components (indirectly involving the driving related structural design of the lens). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The questions in the primary school math competition were difficult. Take the AMC8 competition as an example. It included elementary school mathematics, elementary school Olympiad mathematics, and junior high school mathematics knowledge. It was difficult for junior students. The 25 questions had different difficulty levels: 1 - 5 were easy to get points;6 - 10 were simple but easy to trap;11 - 15 were medium difficulty, which tested the understanding and application of the test points;16 - 20 questions were more difficult, which examined the comprehensive application and required high reverse thinking and calculation ability;21 - 25 were the finale questions, which had challenging knowledge points and had freedom and difficulty. Moreover, students of different systems would encounter different difficulties when facing mathematics competitions like AMC8. This also reflected the difficulty of the primary school mathematics competition questions. At the same time, the Mathematical Olympiad questions were also suitable for those who had experience in the Olympiad, outstanding sixth graders, junior high school students, and extremely outstanding fourth graders and fifth graders. This also meant that it was difficult for ordinary primary school students. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
