One of the main features available on the BT820B is the LVDS video input allowing users to integrate video streams of up to 1920 x 1200 at 60fps on to their displays. An internal real-time video image processing engine on the BT820B can be leveraged by users to apply effects onto incoming video streams via simple command driven operations. MCU resources can be saved by allowing the BT820B to enhance incoming video streams via its video processing capabilities, such as fish-eye effect reduction and gaussian blurs.
Image processing capabilities of the BT820B include:
- 调整大小: 轻松从输入的视频流生成缩略图。
- 模糊处理: Create more appealing user interfaces by blurring the background while keeping the foreground sharp.
- Rotating: Rotate the video easily and apply to shapes (such as cubes) for impressive visual effects.
- 灰度转换: 将图像转换为黑白。
- 特殊效果: 包括: 变暗处理:, 亮度增强:, 反相处理:, 阈值处理:, 对比度增强:, 对比度降低:, 曝光过度处理, 色调分离, Pseudo-HDR, 高级伪 HDR, and 组合 HDR.
- 直方图生成 计算并显示图像直方图用于图像分析。 利用 直方图 来 评估图像的亮度分布,有助于 增强图像处理和优化
