Abstract
A process for measuring the lamina size distribution comprises the steps of uniformly spreading sampled laminae over a conveyor and transporting the same; image-forming the conveyed lamina at a detection region having a given area by using a television camera each time when the lamina moves by a length corresponding to that of the detection region; storing in a memory binary video data which are converted from the video signal obtained by the image-forming; processing the stored video data to encircle continuous ones of the binary data which correspond to the lamina with a rectangular frame; counting the number of continuous ones of the binary data; converting the continuous ones of the binary data in the frame into the other ones binary data after counting; successively carrying out the same processing of different continuous ones of binary data to calculate the size of respective laminae; and measuring the distribution of the lamina size upon the basis of the calculation results.
