本文为电视图像质量的研究提供了渊博而精粹的基础，必将促进我国高清晰度电视的发展。

In global mode, annular omnidirectional images are captured by using skip subsampling mode to guarantee high frame rate, and then unwrapped to cylindrical panoramic images containing global scene information of 360 degrees. In local mode, the location and size of sampling window of image sensor are reconfigured according to the position of interested region, thereby only a corresponding rectangle region of omnidirectional images is captured by using pixel-by-pixel mode, and then unwrapped to a high- definition local perspective image of the corresponding view angle. Finally, a hardware design based on DSP+FPGA is presented.

在全局模式下，为保证采集帧速率，使用行列跳跃模式采集完整的环状全向图，并将其展开为包含360°全局信息的柱面全景图像；在局部模式下，根据感兴趣区域的空间位置设置采样窗口大小及位置，以逐像素采样模式只采集全向图中相应的一块矩形区域，并将其展开为对应视线方向上高清晰度的局部透视图；最后给出了DSP+FPGA结构的系统硬件设计方案。
