Title: Binarization processing method for image
Inventor: KITAGAWA KATSUICHI
IPC: G06T5/00
Filed: 1987-03-09
Abstract: PURPOSE:To accurately extract an object from a background by finding out a mean value of luminance and its standard deviation and finding out a threshold based on an operation formula by using the obtained values and a parameter. CONSTITUTION:The mean value X of the luminance of an image and its standard deviation alpha are found based on image date in an image memory, the threshold Th is determined by using the obtained values X, sigma and a previously set parameter K based on the operation formula of X+Ksigma and the image data read out from the image memory are binarized on the basis of the threshold Th. Even when the background luminance of an image is changed due to the change of illuminating conditions or a measuring object, when there is no object, or when the area of an object is unclear, the threshold is automatically set up to a proper value and the extracting accuracy of the object from the background can be improved.

Title: Automobile sunshade automatic controller
Inventor: FUJIWARA MASANAO
IPC: B60J3/02
Filed: 1981-04-09
Abstract: PURPOSE:To facilitate automatic control of sunshade of an automobile equipped with a roof window by detecting intensity of sunshine by a sensor and controlling the sunshade according to the output thereof. CONSTITUTION:The roof window 3 is opened or closed by manually handling a switch 11. When the roof window is opened, the electric power is fed to the automatic control system, and an optical sensor 8 outputs signals depending upon the intensity of sunshine. A comparator 13 compares this output with the output from a point setter 12. When the sensor output exceeds the setpoint, a close signal is input to the control circuit 10, and a motor 7 rotates in reverse direction to close the roof window. With the manual switch 11 kept on, the roof window is opened again when sunshine becomes weak by the open signal output from the comparator 13. With the manual switch 11 off, this automatic opening and closing is not provided. Thus, the automatic control of sunshade is facilitated for persons in the car.
