The BIT-HPF-104H Projection Splicing and Blending Processor, also known as an edge blending processor, is a professional high - end graphic processing device specifically designed for large - screen projection seamless splicing systems. Its core function is to splice and blend multiple projector display units into a single ultra - high - resolution logical display. This enables the clear presentation of full - screen content such as ultra - high - resolution electronic maps, geographic information systems (GIS), industrial flowcharts, and industrial monitoring data.
Built with a pure hardware architecture, the BIT-HPF-104H eliminates the need for an operating system. This design not only ensures instant boot - up but also avoids issues like slow startup speeds, hardware conflicts, and computer viruses that are common in PC - based architectures. With an average mean time between failures (MTBF) exceeding 30,000 hours, the device can operate continuously for over a year, making it highly reliable for long - term, critical applications.
As a high - end product developed based on screen splicing processors, the BIT-HPF-104H is an all - in - one blending and splicing device. It supports 4K HDMI input and can process and output 2 - 4 channels of high - definition signals in real - time. In terms of blending, the system is equipped with essential functions such as fusion edge feathering, color correction, and geometric correction.
Compared to traditional split fusion and splicing systems, the BIT-HPF-104H offers significant advantages. Its modular and compact system structure simplifies installation and debugging processes. Additionally, it is easier to upgrade and maintain, reducing both operational and maintenance costs for users.
The fusion edge feathering feature of the BIT-HPF-104H is crucial for achieving seamless image transitions. It works by linearly adjusting the image intensity in the overlapping areas of two projectors. This adjustment ensures that the image intensity in the overlapping region matches that of the non - overlapping areas on either side of the fusion edge. The end result is a fused image with uniform intensity and consistent color, completely eliminating visible seams between projected images.
To adapt to various projection display technologies, the device comes with multiple built - in linear Gamma curves. Moreover, users can customize any linear Gamma curve to match specific projector types, including LCD projectors, DLP technology projectors, and laser projectors. This flexibility ensures optimal image quality regardless of the projection equipment used.
In any fusion display project, variations in brightness and color between different projectors are inevitable, even when using projectors of the same brand, model, and production batch. The BIT-HPF-104H addresses this issue with its advanced color and brightness correction capabilities.
The device supports color gamut correction technology. This allows for independent adjustment of the image output by each projector. By fine - tuning the color parameters of individual projectors, the BIT-HPF-104H ensures that the colors displayed by all projectors are consistent. This not only enhances the overall visual effect of the fused image but also maintains color accuracy, which is critical for applications such as medical imaging, art exhibitions, and product design reviews.
Projection surfaces are not always perfectly flat, especially in complex scenarios like curved screen fusion, circular screen fusion, and spherical screen fusion. The BIT-HPF-104H's arbitrary geometric correction function is designed to handle these challenging situations.
The device supports correction for arbitrary curved images. It generates independent grids and enables pixel - level adjustments. Users can set custom nodes to perform local adjustments, ensuring that the projected image is accurately aligned and corrected on irregular screens. This capability makes the BIT-HPF-104H suitable for a wide range of fusion systems, including spherical screens, dome screens, folded screens, and wave - shaped screens.
For applications requiring immersive 3D visual experiences, the BIT-HPF-104H offers passive 3D fusion functionality. In a 3D projection system composed of at least two projectors, each projector lens is equipped with a polarizing filter with an opposite direction. These filters are used to project left - eye and right - eye images respectively.
Viewers wear passive polarizing glasses, where the polarization direction of each lens matches that of the corresponding polarizing filter in front of the projector lens. This ensures that the right eye only sees the right - eye image and the left eye only sees the left - eye image. The human brain then combines these two images to create a 3D perception.
The BIT-HPF-104H overcomes the limitations of single - projector 3D systems, which have restricted projection area and resolution. By enabling edge blending of multiple projectors, it allows for larger - area and higher - resolution 3D stereoscopic effects, expanding the application scope of 3D projection technology.
Projector light leakage is a common issue, where projectors emit a certain amount of light even when displaying a fully black image. When two projectors are used in a fusion setup, this light leakage results in a bright band in the overlapping area during dark field display.
The BIT-HPF-104H's dark field compensation mechanism solves this problem by increasing the light intensity of the non - overlapping areas. This compensates for the bright band caused by light leakage in the overlapping region, ensuring a smooth and natural transition of the dark field image. Regardless of whether the projectors use DLP or LCD technology, the device's unique light leakage band processing technology effectively eliminates the bright band, enhancing the contrast and overall image quality of the fused display.
Unlike PCI bus - based structures that use time - division multiplexing technology, the BIT-HPF-104H adopts backplane switching technology. This technology provides each input and output channel with an independent data channel. As a result, the edge blending processor can transmit all video data in parallel at all times, guaranteeing the real - time nature of video data exchange in the system.
Even in large - scale splicing and fusion systems with a large number of projectors, the BIT-HPF-104H ensures real - time video data transmission without frame loss. This is particularly important for applications that require real - time video display, such as live broadcasts, sports events, and industrial process monitoring.
The BIT-HPF-104H is a single - clock pure digital image processing device. All signals within the system are processed simultaneously under the control of the system's main clock, achieving full - system synchronization. This fundamental design eliminates signal asynchrony issues that can cause image tearing and distortion.
When playing high - speed dynamic videos, the fully synchronized processing ensures that the images displayed on all projectors are aligned perfectly. The result is a 整齐,smooth, and distortion - free large - screen image, providing viewers with an exceptional visual experience.
