Manual PK electric analysis projector three focus

Analyze the three focus application scenarios The actual experience of the projection product friends will know that the first step to adjust the projection screen is focus. Focus, in essence, is the focal process of the lens. Only when the picture is successfully focused, the user can observe clear and sharp pictures.
At present, the focus of the projector mainly includes manual focus, semi-automatic focus, and automatic focus. Although the application methods of these three types of focusing methods are all different, they all use the focusing method to achieve a clear picture.
After understanding the basic process of focusing the projector, we will focus on this article today, in the actual application experience of the projector user, what three kinds of focusing methods mentioned above are more comfortable, and the operation is smoother. In order to deepen the understanding of the current projector focus function.
Return to heart! Intuitive manual focusing without bending The manual focusing method of the projector is mainly achieved by rotating the focus ring. The more advanced laser televisions are more special. Some models use the focus stick on the side of the camera to focus, and some laser televisions do not have a zoom function or a focus function.
By adjusting the focus ring and the focus lever, the user's focusing process becomes more intuitive. As long as the depth of field is within the picture, the user can quickly observe whether the picture is in focus. This feature is suitable for users who need to constantly move the machine. Even under poor light conditions, the user can quickly achieve focus.
It should be pointed out here that the ultra-short-reflection-reflector projector cannot zoom at present. This is because the zoom function adjusts the focal length, and the reflective ultra-short focal projector generally uses a fixed-focus lens, which cannot adjust the focal length, and can only achieve functions such as digital zoom. Therefore, users who purchased reflective ultra-short-focus projectors usually can only find a manual focus ring or a manual focus stick.
Advanced features! Smooth semi-autofocus smoothness The semi-autofocus mode of the projector is relatively simple. There is only one way, that is, it is achieved through remote control buttons. Press the remote focus button for a long time to complete the semi-autofocus result. Throughout the process, the user can constantly adjust by watching the focus indication pattern on the screen.
Some models on the market in order to simplify the remote control button will set a function switch button at the bottom of the remote control, making the volume button function as an auto focus button. When the user is in use, the functions can be switched by simply pressing the bottom button. This type of button will usually be marked "F" or "fn" and so on.
In terms of application experience, this kind of semi-autofocus function is smoother, and users can usually complete it by pressing a key instead of pressing a button. This focusing method can adapt to the situation where the operator and the host are far away. As long as the host can receive the remote control signal, the operator can complete the picture adjustment.
One-button operation! Wide prospects for autofocus In many focus methods, the most promising application is real-time autofocus. It can realize the application operation experience of liberation of the operator's hands. As long as the focus instruction is issued, the host can complete the focusing by itself without the operator constantly observing and adjusting.
In order to achieve auto focus, some models use dual-lens autofocus to achieve more accurate focusing results. Currently, there are three main implementations of the automatic focus function of the projector. The first one is the one-key focus of the remote control through a specific remote control button, and the second one is the click of the relevant application to realize the system's one-key focus. The third kind is that the host fuselage has the focal entity key, can complete the fuselage key presses a key to focus.
These three methods are suitable for different application scenarios. If the operator is far away from the host itself, remote control operation is more suitable. If the body is hoisted, it may be more tedious for the remote control to constantly adjust the ceiling. It is better to find the corresponding function directly from the system. If the host computer itself uses the form of table casting and often moves it, the host button itself will be more reasonable with the focusing entity button.
According to the application scene to choose different focusing products We have mentioned in the above three kinds of focusing methods, namely manual focus, semi-automatic focus and fully automatic focus. The six sub-classes are divided into more detailed: manual focus ring, manual focus lever, semi-automatic remote focus, fully automatic remote focus, automatic system home page focus, and automatic host physical key focus.
So many focusing methods are actually designed for the projector to adapt to different application scenarios. The manual focusing mode is suitable for the situation where the operator and the host computer are close to each other. The operation experience is more intuitive, and it can also adapt to changing scenes and improve the portable application experience. The semi-autofocus mode can adapt to the distance between the operator and the host. The adjustment process is smoother and the entertainment experience is stronger. The automatic focusing method is more suitable for application scenarios where efficiency is required and the projection environment is variable. The entire adjustment process can liberate the hands of the adjuster, and this operation experience is more favorable to users who need to participate in the meeting.
The three types of focusing methods have no advantages or disadvantages, but the projection products using the automatic focusing method have indeed received more and more attention. On the one hand, the popularity of commercial projection products is gradually increasing, people are pursuing efficient use of the products, and on the other hand, the progress of the technology has made the automatic focusing process more direct and effective, and people no longer need to spend too much. The time is waiting for the operation of the motor. It is believed that in the next development of projection products, the application prospects of fully automatic focusing will be even broader, and we will also experience a period of change in projection technology. How will the final result, we will wait and see.

Colored Glass

Colored glass is a kind of optical filter. According to the wavelength classification, it can be divided into sharp-cut filters (L, Y, O, R), sharp-cut filters (W series), and ultraviolet filters (UV-series). Infrared emission filter (IR, RM), blue filter (B), green filter (G), light balance filter (LA, LB), color compensation filter (C), neutral density filter Light sheet (ND), heat absorption filter (HA) multi-band calibration filter (V, HY).
We provide colored glass filters for a wide range of fields such as cameras, optical instruments, physics and chemistry, educational materials, industry and medical care, and can provide spectral characteristics and dimensions according to your requirements.
