The difference and connection between the camera and the human eye
There were the following differences and connections between the camera and the human eye: ** 1. The difference ** 1. ** In terms of structure ** - The human eye was composed of the retina, iris, pupil, and retina, while the camera was generally composed of a lens group, aperture ring, shutter, and sensor. The structure of the human eye was more complicated and precise. - The human eye could be seen as a fixed-focus lens camera. Its equivalent focal length from the retina to the retina was about 25mm, and the pupil diameter could shrink by 2mm and expand by 7 - 8 mm. The focal length of the camera varied according to the type of lens, and its optical structure was obviously different from that of the eye in terms of design and function. 2. ** In terms of performance ** - ** Dynamic Range **: The human eye has a large dynamic range. It can recognize details under different lighting conditions, from strong light to low light. It can see more details under different lighting conditions. Its contrast ratio can reach 100,000: 1. Although the dynamic range of the camera was constantly improving, it was difficult to maintain a clear image under extreme lighting conditions like the human eye. - ** Field of view **: The human eye has a horizontal field of view of about 120 degrees and can observe a wide range of scenes. The camera's field of view was usually small. Although some cameras could achieve wide-angle shooting, there was still a gap between the field of view and distortion control. - ** Three-Dimensional **: The human eye has two independent visual systems (two eyes), which can produce three-dimensional vision. Cameras usually only had one lens (some had special designs such as dual-lens, but the principle was different from that of the human eye), so they could not naturally produce three-dimensional vision like the human eye. Even if they were simulated by software algorithms, the effect was still far from the natural three-dimensional sense of the human eye. - ** In terms of the concept of pixelation **: Although some people mentioned that the human eye had a high number of 576 million pixelated and took up 65% of the brain's "memory," this concept of pixelated was not exactly the same as the concept of pixelated in man-made cameras. The pixelated of a camera was defined based on the number of physical pixelated points on the sensor, and the pixelated increase of a camera was more of a technical means to increase the number of pixelated points on the sensor. The principle of imaging in the human eye was more complicated and was not purely based on this similar concept of pixelated points. 3. ** Function ** - The human eye was a biological organ with an auto-focusing function. It could quickly auto-focus at different distances to see clear images. It was also an indispensable organ for humans to perceive the world, obtain visual information, and communicate with emotions. Cameras were a type of mechanical and electronic equipment. Their main function was to record images. Although some advanced cameras had autofocus, the principle of implementation was different from the human eye. Moreover, the camera itself did not have biological attributes such as emotional communication. ** 2. Contact ** 1. ** Principle of imaging ** - From the perspective of the light path structure, the human eye and the camera had almost the same imaging principle. They both focused the light onto the imaging surface (the retina of the human eye, the sensor of the camera) through the lens (the human eye's corneas and other parts equivalent to the lens). 2. ** Function Analogy ** - To a certain extent, the camera imitated the visual function of the human eye. For example, when shooting pictures and recording scenes, it was to obtain visual information and preserve it in some form. For example, the development of modern camera technology, such as multi-camera simulation of different angles of view of the human eye (wide-angle, telephoto, etc.), simulation of the human eye's auto-focus and adaptation to different light functions, etc., were all based on the visual function of the human eye to carry out technological improvements and innovation.

A Hundred Years of Dream
China's century-old aircraft carrier dream stemmed from the historical lesson of being invaded by the sea by the great powers in modern times. At the end of the Qing Dynasty, China lost its sea power and was invaded by foreign powers. The suffering of modern China began at sea. The failure of the Beiyang Navy proved that bought strength was not true strength. After the founding of the People's Republic of China, for a long time, due to economic and other factors, they could only build a coastal navy. In the 1990s, the US aircraft carrier violated China's sovereignty during the Taiwan Strait crisis and the "Milky Way" incident, which strengthened China's determination to develop a strong navy and have aircraft carriers. The older generation of China leaders had a strong interest in aircraft carriers. For example, Premier Zhou Enlai expressed that he was unwilling to see an aircraft carrier. After the reform and opening up, China's economy developed rapidly, providing conditions for the construction of the navy. In 2012, China's first aircraft carrier, the " Liao Ning ", was delivered to the Navy. It was originally the sister ship of the former Soviet Union's " Kuznetsov ", the " Varyag ". The construction of the Soviet Union was not completed after the disintegration of the Soviet Union. It was successfully modified after being purchased by China in 1998. Prior to this, in order to accumulate aircraft carrier technology, China had also purchased the Soviet Union's " Kyiv,"" Minsk," and Australia's " Melbourne " aircraft carrier for research. In the end, it chose the " Varyag " as the first aircraft carrier because its overall design was similar to modern Western aircraft carriers and its displacement was suitable for long-distance operations. From a global perspective, the development of aircraft carriers in various countries was also a history that witnessed the development of naval forces and the improvement of comprehensive national strength. For example, the United States aircraft carrier developed from a costly first-generation aircraft carrier during World War II to the George W. George W. All of this reflected the importance of aircraft carriers in modern navies and national strategies. It was also the embodiment of countries pursuing the development of aircraft carriers to realize the century-old aircraft carrier dream. The novel " Hundred Years of Spaceship " is equally exciting.
