We all use cameras today, as they are so conveniently integrated into our cell phones, and most of them are of good quality, even though the primary use of your cell phone is intended to be calling and texting and not taking photos. Most cell phone cameras use the CMOS image sensor, which is decent with processing light, so your pictures on darker days could have lesser quality. However, there is another type of image sensor, the CCD camera sensor which does better work on the quality of the pictures. The CCD camera sensor was designed at almost the same time as CMOS and it still has the lead in the CCD vs. CMOS race. The CCD camera sensor has its advantages and disadvantages, so let’s explain them.
The history of CCD camera sensor
The CCD camera sensor was designed in 1969 at AT&T Bell Labs. It was designed by Willard Boyle and George E. Smith and the first uses they wrote down for it were a delay line, a memory, or an imaging device. Soon after that followed the first working CCD camera sensor – it was an eight pixel imaging device. The development was very fast and by 1971 the Bell researchers could capture images with these simple devices. The CCD camera sensor development went on rapidly, and these sensors are still in use today.
How do CCD sensors work?
The CCD sensor, also called the charge-coupled device sensor, catches the light as electrical charge which is then converted into voltage signals. This conversion to voltage is usually done through a small number of pathways, sometimes just one, and it’s done a pixel at a time, while other pixels can be devoted to capturing light. This is the main difference with a CMOS sensor, where all the pixels are individually converted. The CCD camera sensor has better performance benchmarks in fields that require high image quality, but they also use more power than CMOS sensors. The CCD camera sensor usually has more quality and pixels because it was mass produced longer than the CMOS sensor.
Where are they used?
The CCD camera sensor is usually used in cameras that need high quality images, so they are used more by professional photographers and cameramen. Although the CCD camera sensor scores better in image quality, the CMOS sensor is catching up, because they invested much in boosting up their quality. The CCD camera sensor on the other hand is far more expensive because of the manufacturing process which is more complicated, but they also developed cheaper versions on expense of a bit of quality. Even thought the quality of such versions isn’t as high, they are still a very good choice and will deliver remarkable results. So, if you want to have top quality images, we recommend you to find the camera with this kind of sensor integrated, because you will be stunned when you see how much better the quality of images is when you use it.
