The RGB color filter is entirely based on the RGB values, and the main focus of these filters is towards the primary RGB colors. These filters work based on the selected color as this filter will reduce all pixels that are not of the chosen colors. Here we will discuss RGB color filter benefits and some of its demerits with applications.
What is the purpose of an RGB color filter?
In these filters, the R represents the maximum red value. The RGB Color Filter modules have high-resolution monochrome with QImaging’s line in CCD cameras to capture high-quality and remarkable color images. Color data is taken by consecutively receiving full-resolution pictures in each of the color planes. It enables the filter exchange between red, green, and blue states under the camera hardware’s direct regulator.
Moreover, the camera hardware offers precise timing to the filter module and highly synchronized. Thus, artifact-free imaging is much faster at the frame rate than most liquid-crystal filters, mechanically selected filters, and acoustic-optical, which need software control. Also, you can easily control the white balance through the software. This process is done when the filter RGB Color Filter is associated with the camera’s microelectronics with a single cable.
Filter format of the RGB filter
The format of these filters is divided into two parts slider modules and non-slider modules. There are different models as listed below.
1. RGB Color Filter (Slider Modules)
Slider’s modules enable the switching much easier between color and monochrome imaging. There are three types of RGB slider modules such as
This module enables the color filter part to have the movement out and in within the field.
This module slides do the in and out movement much efficiently of the optical path through the nosepiece.
This module slides easily in and out of the optical path through the analyzer slot.
2. RGB Color Filter (Non-Slider Module)
This module is dense, and you can easily replace or detached it for monochrome imaging.
Features of RGB filters
- Liquid-crystal filter element
- Consecutive acquisition of color
- Single-cable linking to Q imaging cameras
- Filter element effortlessly slides out of optical path (slider modules)
- Offers color even when the camera is in binning modes
- Hot-mirror filter
Benefits of RGB filters
- High-quality color images with high-resolution
- Filter color changes with no moving parts monochrome CCD cameras
- No vibration
- High sensitivity and speed
- Easy to install and use
- No optical-registration problems
- Controlled by QImaging cameras
- Full-resolution image in each color plane
- Integrated filtering of infrared light provides better color fidelity
- Enables quick switch between full-color imaging and high-sensitivity monochrome imaging without refocusing
Disadvantages of the RGB color model
Despite the benefits, there are some demerits of these filters, such as:
- It is non-useful for the recognition of colors and object specifications.
- It is a hardware-oriented system.
- It is problematic to regulate a specific color in the RGB model.
Applications of RGB filter
