Title: Detection of inter-row space
Inventor: MINEWAKI TAKAKUNI
IPC: G06K9/36
Filed: 1991-02-15
Abstract: PURPOSE:To detect the inter-row space under less influence of skew by selecting a reference point of a row circumscribed rectangle in accordance with the skew direction. CONSTITUTION:Not only row circumscribed rectangles 22 to 24 and character circumscribed rectangles 25 are extracted but the skew direction of rows is detected from the picture of an input document, and reference points of row circumscribed rectangles 22 to 24 are selected in accordance with the skew direction. The standard row pitch is obtained based on size information of character circumscribed rectangles 25, and the standard row pitch is subtracted from the distance between reference points of circumscribed rectangles 22 to 24 of preceding and succeeding rows in the direction perpendicular to rows and the subtraction result is divided by the standard row pitch to obtain the number of space rows between preceding and succeeding rows. Consequently, the inter-row space is accurately extracted regardless of skew of rows.

Abstract: PURPOSE:To prevent the occurrence of a hazard, e.g., toxication trouble, due to CO, by a method wherein gradient of an increase in a room temperature is detected, the size of a room is calculated from a gradient value, a timer cycle responding to the computed size of a room is decided, and an alarm expediting ventilation of a room is reported. CONSTITUTION:If, when a combustion amount of a burner is identical, a heater is used in a wide room, a rise in a room temperature is slow, and DELTAt is small. In the case of a small room, a room temperature is suddenly raised, and gradient DELTAt is increased to a high value. A computing part 26 computes the gradient DELTAt has the size of a room containing a ventilation rate. A timer part 27 sets a timer time depending upon the size of a room determined by the computing part 26. When combustion is continued for a timer time, an alarm part 28 reports ventilation. Simultaneously with an alarming output from the alarm part 28, a safety timer 30 is actuated. If no ventilation is made until a timer is completed, a safety shut off part 31 is actuated, and a safety valve 10 is closed to stop combustion. When it is decided that ventilation is made before completion of the safety timer 30, the safety shut off part is not operated, combustion is continued, and a timer part 27 starts counting again.
