HDR Auto Focus OV64B40 CMOS 4K Motion Tracking Camera Module

Product Introduction:

This HDR Auto-Focus OV64B40 CMOS 4K Motion Tracking Camera Module is a high-performance imaging product developed by SincereFirst through integration, leveraging the company’s 30 years of experience in the optical device and module industry. It perfectly combines high resolution, strong environmental adaptability, and precise focusing capabilities. At the core of the module is a 64MP pixel sensor, which supports ultra-high-definition 8K@30fps video recording and high-frame-rate 4K@60fps video output. In 4K@30fps mode, EIS can be activated to effectively reduce shooting jitter. The sensor has a size of 1/2 inch, with a single pixel dimension of 0.7μm×0.7μm, and supports 4-pixel binning technology—this technology can equivalently merge pixels into 1.4μm large pixels to optimize low-light sensitivity. Meanwhile, the module integrates HDR and ML-PDAF functions; when combined with an auto-focus motor, it enables fast focusing and motion tracking in complex lighting environments.

In terms of optical design, the module has an Effective Focal Length (EFL) of 4.74mm, with a minimum focusing distance of 28.1cm. It is equipped with an F1.79 large aperture to enhance light intake efficiency, and its field of view covers 79.4°DFOV, 67.2°HFOV, and 53.2°VFOV, while optical distortion is controlled at an excellent level of <1.5%. The lens adopts a 6P (6-element) structure to reduce optical aberrations. For data transmission, a MIPI high-speed interface is used to ensure efficient data transfer. The module is precision-assembled in Class 10/100 COB cleanrooms, adopting SMT technology (RoHS), back-illuminated technology, and AA (Active Alignment) process—achieving a balance between product miniaturization, reliability, and outstanding image quality.

Product Advantages & Features

Millisecond-Level Focusing Speed: Traditional contrast autofocus requires repeated “searching” for the focal point to achieve clear imaging, leading to obvious delays and the “focus hunting” phenomenon. ML-PDAF technology embeds a large number of dedicated phase detection points at the sensor pixel level; it can instantly sense changes in the distance and direction of objects, just like the human eye, and directly drive the lens to move to the in-focus position. This predictive focusing reduces the focusing time to the millisecond level, significantly increasing the success rate of capturing fast-moving objects and fleeting expressions.
High-Quality Low-Light Imaging: In low-light environments, 4-pixel binning technology upgrades the equivalent pixel size to 1.4μm. Combined with the F1.79 large aperture to boost light intake, ML-PDAF still maintains high focusing accuracy in low light, avoiding the out-of-focus issue of traditional cameras in dim conditions. This ensures that human faces and scenes can be quickly locked even in nighttime or indoor scenarios, outputting clear images with rich details.

3. Stable Shooting in Dynamic Scenarios: The fast tracking capability of ML-PDAF works in synergy with 4K@60fps high frame rate and EIS anti-shake, ensuring “accurate focusing, no motion blur, and no blurriness” for moving images. Moreover, SincereFirst provides one-stop OEM/customization support; it can conduct hardware and software adaptation optimization for customers’ devices, flexibly meeting diverse system integration needs ranging from consumer electronics to industrial vision.

4. Exquisite Craftsmanship and Reliable Quality: The entire module is built based on SincereFirst’s over 30 years of industry experience in optical devices and camera modules, as well as its strict quality system. The AA process ensures micron-level alignment between the lens and the sensor, the 6P lens structure guarantees edge resolution, and the MIPI interface enables delay-free data transmission. All products come with an after-sales commitment of 1-year replacement service and 10-year warranty, providing customers with long-term and stable usage assurance.

Product Application

Mini Action Cameras: The fast focusing capability meets users’ needs for capturing outdoor sports and street moments, and can clearly shoot details of food textures and handicrafts. It is suitable for low-light scenarios such as nighttime camping and indoor gatherings—even portable devices can output professional-grade image quality. At the same time, its miniaturized design conforms to the core requirement of “slimness and portability” for such devices.
Vehicle Recognition Systems: It can achieve ultra-fast tracking, quickly capturing and recognizing license plates of high-speed moving vehicles. This ensures clear imaging the moment a vehicle passes through the monitoring area, significantly improving the accuracy of license plate recognition and system efficiency, and providing reliable front-end perception capabilities for intelligent traffic management.
Smart Door Locks: It can quickly lock onto the faces of visitors at the door; even in backlit or low-light nighttime environments, it can accurately recognize facial information, avoiding the problem of “blurry faces caused by slow focusing” in traditional door lock cameras. Low distortion ensures no image stretching, facilitating accurate judgment of on-site conditions during remote viewing.
AR/VR and Eye Tracking: It can track the fast-moving hands or eyes of users in real time, providing near-zero-latency visual feedback for metaverse interactions. Its compact size also makes it highly suitable for integration into lightweight AR/VR headsets.
