如果CMOS克服噪声大的缺点，提高成像质量，CMOS就会超越CCD，成为图像传感器的首选。2012年8月，索尼发布了全新堆栈式传感器（Exmor RS CMOS），需要注意的是，它和背照式传感器并非演进关系，而是并列关系，堆栈式传感器的主要优势是在像素数保持不变的情况下，让传感器尺寸变得更小，也可以理解为，在与背照式传感器的像素数相同时，堆栈式传... 阅61 转0 评0 公众公开 20-01-01 23:46 |
手机摄像头的结构和原理大揭秘。通常所说的“XXX万像素”实际是指相机的分辨率，其数值大小主要由相机传感器中的像素点(即最小感光单位)数量决定，例如500万像素就意味着传感器中有500万个像素点，和手机屏幕中的像素数量决定屏幕是720p或1080p分辨率是一个道理。也就是说，前者1200万像素的手机比后者2000万像素手机的感光面积还要大，这样一... 阅1503 转1 评0 公众公开 20-01-01 23:46 |

Photography is actually just as much a science as it is an art — yet a large majority don’t realize what happens every time they push the camera’s button or open a smartphone camera app. So how does a camera work? Here’s what happens every time you press that button — and how to use a camera to take better pictur... 阅83 转0 评0 公众公开 20-01-01 23:37 |
The sensor is the part of the camera that actually ‘captures’ the image. It’s a complex integrated circuit that typically includes photodetectors – the key component that captures light – plus amplifiers, transistors, and often some form of processing hardware and power management. When the smartphone’s camera s... 阅51 转0 评0 公众公开 20-01-01 23:37 |
These sensors produce very high-resolution images, higher than many DSLR’s. The drawback with packing this many pixels onto the image sensor is that the pixels are tiny and not very sensitive in low light situations. Recently manufacturers have been producing 12-megapixel image sensors that have larger pixels and mu... 阅79 转0 评0 公众公开 20-01-01 23:35 |
How Cameras Work | HowStuffWorksA fully manual single-lens-reflex camera.A still film camera is made of three basic elements: an optical element (the lens), a chemical element (the film) and a mechanical element (the camera body itself).When light waves enter a piece of glass at an angle, one part of the wave will rea... 阅54 转0 评0 公众公开 20-01-01 23:33 |
With that in mind, a 5×7″ photo in print quality (300 DPI) would need to be shot at 3000 x 4200 pixels for best results, or about 12MP. Sound familiar? This is one of the many reasons why Apple and Google seem to have settled on the 12MP sensor: it’s enough resolution to oversample most common photo sizes, but ... 阅48 转0 评0 公众公开 20-01-01 23:32 |
