Functions and actions of the camera processor

The camera processor is an electronic element that controls all its available functions and, in addition, provides pre-processing of the image.

Thus, we can say that the processor is nothing but the brain of the camera.

Functions and actions of the camera processor
The processor interacts with the main components of the camera:

Others that are responsible for shooting modes.
In addition, the processor:

Controls the image stabilization system, shutter, and aperture;
Selects the best exposure mode, lens focus;
Performs processing of information received from the matrix.
The camera software provides the ability to:

Use a variety of exposure metering and focus modes;
To apply the recorded software installation;
Make the noise level less;
Record photo and video files on the memory card and transfer them to other devices.
The processor of the camera and its functions

All characteristics of the processor do not contradict other elements of the system, they are in accordance with the class of the camera.

How does the processor work?
The digital camera processor accumulates information received from different sources.

To get an image, information about the pixel, color depth, and white balance comes from the matrix. Other parameters are taken into account for image generation.

Example of the processor working on landscape photography
Given example.

You select the landscape photo mode. As soon as you press the shutter button halfway to focus, the device immediately starts collecting information.

For example, a digital camera tries to find out the distance to an object, measure the illumination, and apply camera presets to set the exposure (illumination over the entire frame, over the Central area, and over the entire frame with an emphasis on the center).

After collecting information about the range, illumination, taking into account the settings set by the user and understanding that it is the landscape that is being photographed, the camera processor analyzes the received data and sets the final shutter speed and aperture.

The processor of the camera and its functions

For landscape photography, the aperture is set within F/8 – F / 11, and the shutter speed is calculated depending on the lighting.

When you fully release the shutter, the final information is sent to the processor. It looks like a ” raw ” RAW file.

The processor begins further processing this information to produce the final image.

Of course, you want to see a beautiful landscape, because the processor performs the following manipulations:

The sharpness and sharpness settings are set to a higher level;
Added color, saturation;
Illumination rises;
Adjusts the brightness of the scene;
Over-lights and gaps in the shadows are eliminated.
The entire path indicated by the unit of information goes from your first touch of the shutter release with your finger to recording the final image on the memory card.

In order to make the user’s life as easy as possible and minimize their participation, the processor performs all possible functions for them.

If you add the use of automatic mode here, the processor analyzes the scene before the shutter is released. It takes into account:

Presence of dynamic objects in the frame;
Presence of persons, children;
Movement of the camera itself;
Contour light.
Depending on the type of scene, the processor will select the best mode for shooting:

Focus type;
Need for long exposures;
The need to soften the image for a portrait or increase the sharpness for subject photography.
Of course, all this can be done by a photographer, taking pictures in manual mode and giving preference to subsequent independent processing in photoshop.

No matter how stable your camera is, its stability is completely useless when shooting moving objects. Only a short shutter speed will help freeze the movement. This is why when…

Modern cameras are equipped with a built-in exposure meter, which is able to automatically assess the level of illumination and select the appropriate values of the exposure parameters. If the…
