[What are the weak points?] Think about the advantages/disadvantages of "digital inner mirrors" that spreads rapidly

Level comparable to mirrors

Toyota Gran Ace, which appeared as a full -size wagon that can be selected from 4 rows and 8 people, is 5 in length..3m.Since the digital inner mirror is standard equipment, the backward view is secured even when riding the capacity.

Writing: HAJIME AIDA (Hajime Aida) edited: TETSU TOKUNAGA (Toru Tokunaga) Recently, the "digital inner mirror" has been adopted one after another. [Photo] Digital room mirror type draleco [2 camera type] (26 sheets) The image of the camera installed at the top of the rear window is reflected on the liquid crystal display installed instead of the room mirror (mirror). Not only, but also for mini cars, there are a wide range of examples. Some models have spread this system to the side mirror. This is due to the revision of the international standards for back mirrors and the use of the "camera monitoring system" instead of the back mirror. In Japan, the security standards were revised in June 2016, making it possible. As a background, the liquid crystal display has been able to demonstrate sufficient abilities with resolution and brightness, and the display has been performed almost in real time. In other words, the fact that the device reached the display ability comparable to the conventional mirror, which is a mirror, brought this realization. So what are the benefits of digital inner mirrors? The biggest advantage is that the visible range is greatly expanded. The room mirror is installed at the top of the driver seat. Therefore, from this position, the rear can only be confirmed through the rear window. If a person is riding in the rear seat or loading luggage, the back will be almost invisible depending on the situation. In that regard, the digital inner mirror monitors a camera video installed at the top of the rear window, so the backward can be displayed without any effect in the car. This can be said to be particularly beneficial for long -body models such as minivans. The size of the viewing angle is also a great advantage.

The advantage of adjusting the brightness of the viewing angle and the night road

In the Mitsubishi mini car, the EK series, you can select a digital inner mirror (a digital room mirror in Mitsubishi) in the manufacturer OP.

In the digital inner mirror, the projected range depends on the angle of view of the camera, so you can get a considerable view depending on the specifications. In addition, if the camera sensor has enough room, it is possible to change the range to be reflected up and down and left and right. In addition, the back view does not worsen as a design that raises the rear deck or narrows backwards due to the design. There is no doubt that this will lead to safe driving. As a room mirror, you can save the trouble of adjusting the angle for each driver. Despite being a digital inner mirror, the displayed liquid crystal display is the same as a TV or smartphone. In other words, even if the angle to be watched changes, the direction of the projected image does not change at all. In the past, there was an inverted phenomenon in which the screen darkened depending on the viewing angle, but a large liquid crystal display with a wide viewing angle was developed, and there was almost no problem. You can no longer think that digital inner mirrors need to change the angle anymore. And there is an advantage that I could not get with another mirror. That is brightness. Camera used in monitoring systems, not limited to digital inner mirrors, can be reflected brightly in the daytime even at night if the sensitivity is enhanced. Of course, the problem of increasing the sensitivity will increase the number of noise, but the camera used for in -vehicle monitoring has improved noise reduction processing, and this problem is almost solved. So are there any disadvantages? Unfortunately, digital inner mirrors may not be happy to let go. For better or worse, it's all about checking the back through the LCD display.
