MJPEG Video capture device using MJPEG

An imaging apparatus includes at least one processor to implement: a re-sizer configured to re-size an image to a predetermined size, an encoder configured to encode the re-sized image, and a frame rate controller configured to calculate an actual bit rate of the encoded image for a preset period of time, compare a user-set target bit rate with the calculated actual bit rate, adjust a frame rate of the encoded image according to a result of the comparison, and output an encoded image signal at a user-set target bit rate irrespective of a complexity of the encoded image. 本发明提供种使用MJPEG压缩方法的成像设备。所述成像设备包括：大小调整器，被配置为调整图像大小到预定大小；编码器，被配置为对调整大小的图像进行编码；帧率控制器，被配置为针对预设时间段计算编码的图像的实际比特率，并将用户设置的目标比特率与计算的实际比特率进行比较，根据比较结果调整编码的图像的帧率，从而不考虑编码的图像的复杂度而以用户设置的目标比特率输出编码的图像的信号。
