摘　　要：传统的胶囊内窥镜采集并传输模拟式图像,抗干扰能力弱,帧率低,分辨率低,该文提出了一种新型的数字式胶囊内窥镜,该胶囊采集传输数字式图像,帧率达到30帧/秒,分辨率为400×400像素。图像在胶囊内部压缩,在上位机上实现图像的解压缩和插值。根据胃肠道图像特点,该文提出了一种新型的插值算法,利用图像平面之间的关系,得到较高质量的彩色图像。Traditional capsule image collects and transmits analog image, with weak anti-interference ability, low frame rate, low resolution. This paper presents a new digital image capsule, which collects and transmits digital image, with frame rate up to 30 frames / sec and pixels resolution of 400×400. The image is compressed in the capsule, and is transmitted to the outside of the capsule for decompression and interpolation. A new type of interpolation algorithm is proposed, which is based on the relationship between the image planes, to obtain higher quality colour images.
