Analysis of Key Technical Specifications of Camera Modules

Image Sensor: This is the core component of a camera module responsible for converting light signals into electrical signals. Common types of image sensors include CCD and CMOS.

Image Signal Processor（ISP\DSP）: This is used to process the raw image captured by the image sensor, including color correction, contrast enhancement, and noise reduction, to improve the quality of the final image. The working principle involves the light the object being focused by the lens, converted into electrical signals by the CMOS or CCD integrated circuit, and then processed into digital image signals by the internal image. These signals are output to the DSP for further processing, and finally converted into standard GRB, YUV, etc. format image signals.

Lens: This is responsible for focusing light onto the image sensor. Different types of lenses are suitable for different application scenarios, such as wide-angle lenses for large scene shooting and tele lenses for distant target shooting. Lens design utilizes principles of light such as straight-line propagation, reflection and refraction, wave nature, interference, and diffraction., the material and coating of the lens can affect color reproduction and light transmission. Common lens constructions include 1P, 2P, 1G1, 1G2P, 2G2P, 4G, etc., all of which function as a convex lens.

Resolution: This refers the level of detail that a camera module can capture, typically expressed in pixels. Higher resolution means clearer and more detailed images.

Frame Rate: This indicates the number image frames transmitted per second. A high frame rate provides smoother images.

Sensitivity: This refers to the sensitivity of the camera module to light, affecting the imaging in low-light conditions.

Focal Length: The focal length of the lens determines the image formation, field of view, depth of field, and perspective strength.

Of View (FOV): This reflects the shooting range of the image, related to the focal length.

Aperture: This is an adjustable optical mechanical diaphragm located inside lens, used to control the amount of light passing through the lens.

Depth of Field: When an object is in sharp focus, all objects within a certain distance front of and behind it will also appear sharp.

Voice Coil Motor (VCM): This is used to achieve auto-focus function by adjusting the position of the lens to present a image.

IR-CUT Dual Filter: This is a filter system built into the camera lens group that can automatically switch filters based on the strength of external light to the best imaging effect.

Light Guide: This is used to guide light into the interior of the camera module, improving image quality.

Light Source Component: This is in conjunction with the light guide to provide additional light for the camera module, especially in low-light conditions.

Fixed Focal Length Lens and Zoom Lens: A fixed length lens has a fixed focal length, while a zoom lens can change its focal length to adjust the shooting range and perspective.
