Filed: 1983-10-24
Abstract: PURPOSE:To supress unnecessary sound and to collect efficiently voices of plural speaking persons by arranging one microphone element at the center and four microphone elements on circumferences of concentric circles, and constituting a sound-collection system by changing the weight at the center and on the circumference. CONSTITUTION:A microphone element 5 is installed at the center and in addition, microphon elements 1-4 are installed on circumferences of concentric circles.

IPC: H04N5/349
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain a still image with high resolution whose dynamic range is extended with a memory of a small capacity. SOLUTION: A plurality of images with different exposure are obtained at a 1st image pickup position and stored in a memory 5. A D range magnification DSP 7 reads the images and composites them to obtain one still image whose dynamic range is extended and the image is stored in a memory 6. Then picture elements are shifted to a 2nd image pickup position and the similar processing is conducted at this position to obtain a still image whose dynamic range is extended, and the image is stored in the memory. Since a plurality of still images whose dynamic range is extended are stored in the memory by conducting the processing above at a plurality of image pickup positions, a picture element deviation DSP 9 and an FR processing YC generation DSP 10 are used to process the still images to obtain a still image with high resolution whose dynamic range is extended.

IPC: G03B9/02
Filed: 1987-08-07
Abstract: PURPOSE:To reduce the size and weight of a motor-driven stop device and to control the stop tool closely by forming a 1st gear plate of a magnetic body and eliminating the need to arrange a magnet on a surface facing a 2nd gear plate, and driving the stop tool through the differential rotation between the 1st and 2nd gear plates. CONSTITUTION:When a control current flows through winding 16 in order, magnetic flux is produced in the axial direction of the 2nd gear plate 15 to attract the 1st gear plate 11 and 2nd gear plate 15, and a 1st tooth part 11b and a 2nd tooth part 15a engage each other in order. Then the 1st and 2nd gear plates 11 and 15 differ in the number of teeth and one is restrained from rotating, so the other gear plate which is restrained rotates to drive the stop tool 18, thereby opening and closing an optical path through the sliding of stop blades. Further, the 1st gear plate 11 is made of the discoid annular magnetic body and a magnet need not be arranged separately, so the whole device never increases in size axially.
