The camera module clock is the signal frequency that makes the integrated circuit operate. The MCLK (Master Clock) refers to the basic clock input for the integrated circuit. In contrast, the PCLK (Pixel Clock) refers to the clock for the data output from the integrated circuit.

The camera module exposure time is the time for which the sensor is exposed to light. It can be adjusted within a range of a few milliseconds to a few dozen milliseconds. This exposure is the brightness index of the image. The Auto Exposure (AE) function automatically adjusts the exposure according to the ambient brightness and IC register settings.

The camera module's white balance is the correction applied to adjust the hue in color cameras. And Auto White Balance (AWB) is a function that automatically adjusts the white balance according to color information from the surroundings or the settings of the IC register.

IR/NIR, in relation to camera modules, refers to infrared and near infrared light in wavelengths of roughly 840 nm to 950 nm. These wavelengths of light cannot be seen with the naked eye, but can be picked up by image sensors, and are sometimes used. IR Cut Filters (IRCF) are optical filters that block infrared light.

The camera module depth of field describes the range over which the entire image is in focus. This is referred to as "shallow" or "deep". And the F value gives the aperture of the lens. Generally, a small F value results in a shallow depth of field, and a large F value results in a deep depth of field.

A camera module's image circle refers to the circle or range over which the light that passes through the lens forms an image. The way the image looks is determined by the size of the image circle and the size of the light receiving area of the image sensor. The optical axis is the center of the image circle and the axis of the optical center.
