دوربین 2 مگا پیکسل OV2640 - با فلت 20mm

Description:

The OV2640 2-megapixel camera is a CMOS image sensor with a resolution of 1632×1232. Despite its small size and low operating voltage, it provides all the features of a single-chip UXGA camera and image processor. This module uses an SCCB interface (similar to I²C) for internal settings and allows receiving 10-bit sampled data in full-frame, sub-sampling, and windowing modes.
The OV2640 camera's maximum frame rate at UXGA resolution (1632×1232) is 15 frames per second, giving users full control over image quality, data format, and transmission method. Additionally, it supports various output formats, including RAW RGB, YUV/YCbCr 4:2:2, RGB565/555/444, and GRB 4:2:2, making it ideal for image processing and machine vision applications.
This compact camera module features an advanced internal image processing system, including gamma correction, white balance adjustment, saturation control, color correction, noise reduction, and dead pixel correction. These features ensure high-quality output images with minimal noise.
In terms of hardware, this module operates on a voltage range of 1.7V to 3.3V and includes an internal LDO regulator to supply 1.2V to the core. It has extremely low power consumption, using less than 20μA in sleep mode. The standard lens field of view (FOV) is 70 degrees, and the sensor's pixel size is 2.2µm × 2.2µm. The signal-to-noise ratio (SNR) is 40dB, and the dynamic range is 50dB, making it a reliable choice for various applications.
The OV2640 module uses OmniVision’s advanced imaging technology, which applies image processing algorithms to minimize issues such as Fixed Pattern Noise (FPN), Tailing, Floating Noise, and other image distortions, producing sharp, stable, and high-quality color images.
Due to its compact size, low power consumption, and versatile output compatibility, the OV2640 camera module is an ideal choice for embedded systems, machine vision, IoT applications, robotics, surveillance, and facial recognition systems. It is also well-suited for microcontrollers like ESP32 and Arduino, making it accessible for developers to integrate into their projects.
