Title: Electric blanket
Inventor: INOUE MASAATSU
IPC: H05B3/00
Filed: 1987-07-16
Abstract: PURPOSE:To ensure enough warm feeling in lying on or below an electric blanket and save consumption power by determining preheating time depending upon room temperature via detection thereof. CONSTITUTION:The temperature of the room wherein an electric blanket is used, is inputted as a temperature signal to a microcomputer 10 via a thermistor 12 arranged within the blanket. The microcomputer 10 operates timer control time depending upon the room temperature and controls a thyristor 15 to turn ON and OFF until the termination of the operated timer control time via a comparison between a temperature signal obtainable as the voltage of a temperature sensing circuit 22 and the constant predetermined temperature. When timer operation terminates or there is no timer control demand signal, a comparison is made between a temperature signal obtainable as the voltage of a resistor 16 and a temperature signal from the temperature sensing circuit 22, thereby controlling the thyristor 15. As a result, pertinent preheating can be made regardless of a room temperature level.

Title: Image color quantizing method
Inventor: MORI YUICHI
IPC: G09G5/02
Filed: 1993-07-20
Abstract: PURPOSE:To enable a user to intervene in the number of assigned display colors in color quantization to a specific area in an image by producing a color histogram of a full color image with addition of a weight coefficient and deciding a display color based on the color histogram. CONSTITUTION:Asking a user about the setting propriety of the new color quantization weight, an area where the weighting should be carried out, is segmented in response to the operation of the user. Then, the color quantization weight coefficient is set for each area (102) by means of a mouse and a keyboard. The frequency value set in a color histogram for the picture elements included in an area where the weight coefficient is set larger than the default value can be relatively increased against the frequency value of picture elements included in other areas of smaller weight coefficients. Thus, the color quantization is carried out based on the color histogram (103, 104). By this, it is possible to assign many display colors to an area having large frequency in the color histogram and then to assign a small number of display colors to an area of small frequency respectively.
