Understanding imaging of camera module

Camera imaging refers to the process of capturing and creating images using a camera. It involves the use of various components and technologies to capture light and convert it into a digital or analog representation of a scene.
The basic components of a camera imaging system typically include:

   1. Lens: The lens captures light from the scene and focuses it onto the camera's image sensor or film. Lenses play a critical role in determining the field of view, focal length, aperture, and image quality.
   2. Image Sensor or Film: The image sensor (in digital cameras) or film (in traditional film cameras) receives the focused light and records the image. Image sensors convert light into electrical signals, while film captures light on a photosensitive emulsion.
   3. Shutter: The shutter controls the duration of light exposure to the image sensor or film. It opens and closes to allow light to reach the sensor or film, determining the exposure time.
   4. Image Processing: In digital cameras, image processing algorithms are applied to the raw sensor data to optimize image quality, adjust colors, reduce noise, and enhance details. This processing may happen in-camera or during post-processing on a computer.
   5. Storage: The captured image data is stored in digital cameras on memory cards, while in film cameras, the image is recorded directly onto the film.

FOV (Angular Field of View)

AFOV stands for "Angular Field of View," which refers to the extent of the observable scene that a camera can capture. It represents the angle, measured in degrees, between the two extreme rays of the field of view (FOV) from the camera's lens.

The FOV of a camera module depends on various factors, including the focal length of the lens and the size of the camera's image sensor. A wider focal length or a smaller image sensor size generally results in a larger AFOV, while a narrower focal length or a larger sensor size leads to a smaller AFOV.

To calculate the AFOV of a camera, you can use the following formula:

AFOV = 2 * arctan (D / (2 * F))

AFOV is the Angular Field of View in degrees.
D is the diagonal dimension of the camera's image sensor.
F is the focal length of the camera lens.

Global shutter vs Rolling shutter

Rolling shutter cameras capture the scene line by line, from top to bottom, causing a time difference between top and bottom parts. Motion or camera movement results in the distortion known as the rolling shutter effect.

On the other hand, global shutter camera is designated to capture an image by simultaneously exposing all the pixels in its image sensor to light for a brief period of time. Unlike a rolling shutter camera, which scans the image sensor row by row, a global shutter camera captures the entire image instantaneously.

UVC protocol

The UVC protocol, also known as USB Video Class, is a standard protocol that defines how video streaming devices, such as webcams or digital cameras, can communicate with computers over a USB connection. It allows these devices to be easily recognized and used by various operating systems without the need for additional drivers or software installations.

Plug-and-Play: UVC is a plug-and-play protocol, meaning that when a UVC-compliant device is connected to a computer via USB, the operating system automatically detects and configures the device without requiring manual driver installation. This makes it convenient for users as they can simply connect the UVC device, and it will be ready to use.

Cross-Platform Compatibility: UVC is designed to work across different operating systems, including Windows, macOS, Linux, and Android. This compatibility ensures that UVC-compliant devices can be used with various devices and platforms seamlessly.

Video Streaming and Control: The UVC protocol defines the necessary commands and data formats for video streaming and control functions. It allows the video data captured by the device to be transferred over USB and decoded by the receiving software on the computer. It also enables control of parameters such as resolution, frame rate, exposure, and focus settings.

Device Enumeration: UVC provides a standardized way for the computer to enumerate and identify connected UVC devices. It allows the operating system to recognize the device's capabilities and features, making it easier for software applications to interact with the device.
USB Compliance: UVC operates within the USB framework and adheres to USB specifications. It leverages the capabilities provided by USB, such as data transfer rates, power management, and device configuration.

Application Support: UVC is widely supported by various software applications, including video conferencing software, video recording software, and video streaming platforms. This broad support ensures that UVC-compliant devices can be used with a wide range of applications without compatibility issues.
