Abstract

PURPOSE:To facilitate the preprocessing adapted for the purpose, by making the picture signal binary and by counting data of the picture pattern in accordance with the purpose. CONSTITUTION:Solar image 11 projected on the CCD image sensor is divided into faces 12, 13, 14 and 15 having 64X64 constitution. Data 0, 1, 2 and 3 are written into memories corresponding to thse divided faces. Therefore, when the sensor scans the region of face 12, memory outut 6 becomes 0, and data which passed through binary circuit 7 is led to the 0th counter of counter group 9 by multiplexer 8. Consequently, numbers proportional to areas of solar image 11 projected onto respective divided faces are counted by counters corresponding to respective divided faces. If the direction of picture converting device 1 is so determined by a computer that these divided areas are equal to one another, this direction becomes the center of the sun, and tracking is possible.
