| What is computational photography and how did it affect phone cameras? |
Smartphone cameras have completely changed the photography process. Anyone can take unique and professional photos without the need for expensive cameras. Especially with techniques like computer imaging.
Here, taking pictures with the smartphone camera is not as easy as it seems to the user because the smartphone performs many operations to take pictures on the go. With the click of a button, many rely on computer imaging. Technique.
A modern smartphone camera can be considered as an independent computer, the imaging process relies on a dedicated processing core to convert the information received from the sensor into information that is displayed as a final image on the screen.
Computer photography in smartphone cameras
The recording process begins with the camera sensor, which is made up of several semiconductors that are highly sensitive to light. It ends when the last image is displayed on the smartphone screen.
The camera sensor of the smartphone is covered in red, green and blue. When the sensor collects information, the colors in the image are automatically assigned to those colors.
Of course, smartphones use various imaging algorithms to map and reset colors, eventually displaying true-color images that mimic the colors of the object being photographed.
The image goes through an additional step, which is to highlight the color and adjust the degree of change of the color level according to the algorithm provided to it. Mainly because the smartphone screen can display millions of colors and the phone camera can capture them.
At the end of the process, the smartphone camera converts the colors that are very close together into a single color. This is because the human eye often cannot distinguish between them.
One of the most important operations in computer imaging after editing and improving the image is to compress it so that it does not occupy a large storage space.
Photography has gone through many stages, including the process of defining the edges of each element of the image and increasing the clarity and saturation of the image. Over time, AI-based computer imaging could make this process easier and faster.
The importance of computer photography is reflected in the way some shooting modes work, such as background isolation or night photography. Perhaps the most prominent example of a phone with a high CP level is the Google Pixel.
