Many people today use cameras on a daily basis, especially after their integration into cell phones and thus becoming available to almost everyone. As you already know, the quality of the pictures taken with such cameras isn’t really the best, and you may have always wanted to have a proper camera. Before you decide to buy one, you should do some reading – an expensive camera doesn’t necessarily mean it is the best for you. There are many different factors you should be aware of. If you want the highest quality camera and you done your fair amount of reading, you may decide to buy a CCD camera. Now you have to find the right one, and still do a bit of reading on CCD sensor sizes. Many people find it difficult to understand CCD sensor sizes and it can be hard to find someone who knows this. In this article, I will explain different CCD sensor sizes and investigate the question of whether size really does matter when it comes to CCD sensors.
CCD sensor sizes
Whenever you browse an online market to see which camera you would buy, you stumble across specifications such as aspect ratio, pixel size, sensor type and more. You may understand most of them and you may know what kind of aspect ratio you want, how many pixels it should have, and you decided you wanted a CCD sensor. There is one tiny thing you didn’t look up yet, and that is the CCD sensor sizes. CCD sensor sizes are usually marked as a “type” – the numbers you can find on them are usually in fractions, like 1/2.3” or 2/3”. This is actually larger than the real sensor – this sizes date back to sizes of TV camera cubes in the fifties. Also, compact cameras usually have smaller CCD sensor sizes and are not that sensitive to light.
What exactly do these numbers mean?
These CCD sensor sizes don’t represent the diagonal of the sensor; they represent the outer diameter of the glass envelope. Usually the sensor is two thirds of the written size. So to see the real CCD sensor sizes it’s best to calculate them using the two thirds rule. So if you want a camera that has the 1/1.7” type with an aspect ratio of 4:3 and the diameter of the tube being 14.941 millimeters, the real sensor size will be 7600 millimeters in width, 5700 in height and the sensor will be 9500 millimeters in diameter. You can find the CCD sensor sizes charts online so you can determine which size you want.
Does CCD sensor size matter?
You see that the price of the camera grows with CCD sensor sizes, so it must be important in some way. CCD sensor sizes determine the number of pixels, so the bigger the sensor, the more pixels your image will have and therefore it will be clearer. One thing you have to watch out when picking among CCD sensor sizes is that the size isn’t too big for the lens, because the image will seem like it fades out, and the edges of the field are dark, resulting in a tunnel effect.
