それなら逆にimshowが必要です。

**This function should be followed by cv::waitKey function** which displays the image for specified milliseconds. Otherwise, it won't display the image. For example, waitKey(0) will display the window infinitely until any keypress (it is suitable for image display). waitKey(25) will display a frame for 25 ms, after which display will be automatically closed. (**If you put it in a loop to read videos, it will display the video frame-by-frame**)

**The function only works if there is at least one HighGUI window created** and the window is active. If there are several HighGUI windows, any of them can be active.
