Best smartphone camera image sensor format size

A Camera Sensor Format is extremely significant as it defines the size and shape of a digital cameras imager sensordefining how the camera takes and transfers imagery, light, noise, and colors into pixels or an image.

Most manufactures and consumers alike lean towards lower camera sensor formats due to cost and technology requirements.

For example, the IPhone 5, 5s, 6, and Nokia Lumia 720 all utilize a 1/3” camera sensor format—as 1/2 and 1” involve substantially more expensive technology (size) and format, even with the most premium, best-selling smartphones.

When companies install camera sensor formats under the 1/2” sensor size, it avails for more economical based pricing, (unfortunately) lower quality technology, but requires less labor involved manufacturing, so it’s more profitable for the companies that produce them.

Ultimately, it will also come down to the type of image censor, such as CCD or CMOS (more common in today’s smart phones vs. CCD being more popular in high-end digital cameras), and what the image sensor size will be for each. Not only this, but performance is taken into consideration and will vary, as well as ability to function with higher or lower light pollution, to use it as an advantage to generate pixelated images, and the transfer speed of each image and the methods in which it applies.

Lastly, global shutter features on CMOS smart-phones play a large role in popularity as it increases the speed, yet depletes many smart-phones of image quality. This also includes a depletion of quality with moving images—or for example, panoramic imagery.
As CCD was the original technology utilized with global-shutter technology, CMOS will be slower to catch on to this trend and produce likewise quality imagery technology in their smart phones and cameras.

In the meantime, the blurring effects seen with CMOS technology and a 1/3” camera sensor format will continue to take place as this is considered a lower-end optic value and therefore suffers from less accuracy and speed in image capture to pixilation.

CCD vs CMOS sensor for Camera Mobile Phone/smartphone

While more pricy and power-consuming, CCD (Charge Couple Device) camera-sensors in today’s smart phones perform better and provide more accurate, detailed imagery in a wider picture than those using CMOS (Complementary Metal Oxide Silicon) technology.

Most modern smartphones today are made using CMOS technology because of its ability to pump out more images and utilize voltage (with less power consumption) to translate images captured into pictures. CCD sensor technology on the other hand, strictly uses light as its base for capturing images, and does so at the same time utilizing its internal silicon components, unlike most CMOS technology seen in smart-phone cameras.

CMOS is most desirable for smartphone manufacturers because it uses a low-power and more energy-friendly method between its output amplifier associated with each pixel or group of pixels captured in an image. Ultimately, the charge is converted into voltage, and then transferred into an analogue signal (using chip technology within a smart phone) and then in turn translated into your image.

Arguably, exposure to image capture is much more consistent with CCD technology, since it relies strictly on photons and silicon technology to generate electrons which represent an image.

Using electronic pulses CCD technology then relays to you (your smart phone) the image or images strictly reliant on light capture associated with the environment in which you took the image. While high moving total bandwidth performance in capturing images with smart-phones is desirable for most smart-phone users (users don’t like a long wait), CCD is still considered a more primal, high-performing, and accurate form of smart-phone camera technology.

For those that can afford it, CCD smart-phone camera technology makes sense, if they have the patience to wait for the transference of the image to be captured, translated, and loaded. CCD sensor technology, including in smart-phones, has always used a global shutter pixel technology, while CMOS technology, for example, has only recently picked up on and attempted to compete against CCD sensor technology with similar a technological approach.
