Đề bài: The picture below shows how a digital Single-Lens Reflex (SLR) camera works. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
The diagram illustrates the operating mechanics of a digital Single – Lens Reflex camera. In short, the camera works by moving a mirror up and down through the press of a button known as the shutter.
When the shutter is untouched, light travels through a series of lenses to reach a mirror that blocks the CMOS sensor behind it. The light is then reflected perpendicularly upwards to a penta-mirror and got redirected to an opening at the back. Through this opening, the image reaches the photographer’s eyes, enabling the camera holder to view the exact picture that is going to be taken.
Once the shutter is released, the reflect mirror swings up, lying flat. The light can now reach the digital sensor to be processed, and the captured data is subsequently processed in the CPU. The final photographed data is displayed on a screen and got stored in the memory card. (150 Words)
