IPC: H04N5/225
Filed: 2001-02-22
Abstract: PROBLEM TO BE SOLVED: To detect more than one face in an image so as to improve the quality of a captured image by adding a value to image capturing processing. SOLUTION: A method for determining the presence of a face from image data is performed by comparing facial models for searching more than one face candidate regions with facial probabilities to previously screen the image data with a first algorithm, and by performing operation on the face candidate region with a second algorithm by pattern matching so as to check each face candidate region and to confirm the presence of a face in the region. As for detection level, a combination of the first and second algorithm has a higher performance than the individual algorithm. A digital camera includes a memory for storing an algorithm and an electronic processing unit for processing image data with algorithm so as to determine the presence of more than one face in the scene.  The facial data is used for controlling exposure parameter of image capturing or for producing processed image data that associates color balance to the presence of faces.

When temporary stop instruction is not received during the reception of the image data, received picture data are raster-developed (S6) and the printer changes to printing processing (S7).  When the temporary stop instruction is transmitted from the computer during printing (S8), the printer operates, until the processing of transfer paper during printing is completed. When the processing is completed, the printer awaits for the next instruction from the computer, while remaining pictures are kept stored in a HDD. If there is no temporary stop instruction given during the printing, the printing of image data for each page is completed (S9), and printing operation is terminated, after the whole pages have been printed (S10 and S11).

Title: Tensioner
Inventor: KOSUGE HIROSHI
IPC: F16F9/50
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a tensioner capable of preferably following a large variation of a vibration mode and realizing a damping thereof by utilizing a fluid pressure by a fluid generally used. SOLUTION: The hydraulic tensioner utilizes a circulation resistance obtained when a viscous oil in a cylinder 3 receiving an insertion pressure flows in a gap of slide surfaces of the cylinder 3 and the plunger 4 when the plunger 4 is inserted into the cylinder 3 filled with the viscous oil. For example, a stepped part is axially provided on the slide surface of the inserted plunger 4 side. A distance of the gap can be varied by whether or not the stepped part is inserted into the cylinder 3 and the circulation resistance of the fluid is varied to change a damping force of the hydraulic tensioner. The hydraulic tensioner is applied to a belt of which a tension vibration mode is varied. A large damping force is generated when the vibration of the belt is large and a small damping force is generated when the vibration of the belt is small.  Thereby, a stable action of the belt is obtained without making the tension excessively large.
