Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To easily decide an image processing parameter for emphasizing and suppressing a face image according to the size of the facial image included in an image. SOLUTION: An image indicated by image data S is displayed on a display means 2, and positions P1 and P2 of the width direction of a face image are designated by an inputting means 3 such as a mouse. An estimating means 5 calculates a distance between the positions P1 and P2 based on the designated positions P1 and P2, and calculates the size F of the facial image from this distance.

Title: Idle revolution control device for engine
Inventor: TAKAI AKIRA
IPC: F02D41/08
Filed: 1983-07-29
Abstract: PURPOSE:To effectively prevent the number of idle revolutions from dropping by allowing an external load to be substantially applied to an engine while delayed by prescribed time after turning a load operation switch on upon operating the engine with small fine low speed torque. CONSTITUTION:When, during a two cylinder operation, a cooler is operated by turning a load operation switch 24 on, a secondary target P22 of a bypass valve 16 is computed by employing a primary target position P21 of the bypass valve 16 and a correction amount DELTAP22 of the valve 16 yielded by previously anticipating the number of idle revolutions dropping by the cooler operation so as to correct said number to permit a final target value P0 of the valve 16 to be computed by said computed value and a correction amount DELTAP21 yielded on the basis of the number of revolutions. Based on this P0, the valve 16 is controlled, and further an initial value of a delay timer is decremented. A series of controls are repeated till the timer value reaches 0, and upon reaching 0, a solenoid clutch 25 is connected to operate the cooler. Hereby, the cooler is operated delayed by prescribed time after turning the switch 24 on, so that when the cooler load is actually connected, the number of idle revolutions has been already increased by the prescribed value. Thus, there is no dropping of the number of idle revolutions.

Filed: 1987-06-05
Abstract: PURPOSE:To improve an execution efficiency by comparing the address signal of a microprocessor and the output address signal of a latch circuit, outputted before it, and executing a refreshment when a refresh timer to extend an interval is timed out. CONSTITUTION:The microprocessor 1 accesses a memory 8 through a bus arbiter 7. Besides, the latch circuit 2 latches the address, outputted by the processor 1 in order to fetch an instruction. At every time when the instruction is newly fetched, its address and the output address of the circuit 2 are compared by a comparator 3. The comparator 10 compares the difference of the output of the comparator 3 and the output of a constant value generation circuit 9, an detects that a branch instruction is executed. The refresh timer 4 is not timed out if it is just after the branch instruction is executed, and when the timer 4 is timed out, a control circuit 5 executes the refreshment. Thus, the refreshment is not executed immediately after the execution of the branch instruction, and the execution efficiency can be improved.
