Title: Video camera device
Inventor: TAKASE SATOSHI
IPC: H04N5/232
Filed: 1992-12-24
Abstract: PURPOSE:To prevent the deterioration of the resolution of a reproduced image when the shake of a screen caused by the camera shake, etc., is corrected by moving equivalently the scanning area of an image pickup element by interpolation processing. CONSTITUTION:The camera shake quantity detected by a shake sensor 12 is sent to a control circuit 9 and a coefficient alpha is set in an electronic zoom processing circuit 7 in response to the detected camera shake quantity. The output signal of an image pickup element 2 is supplied to a signal processing circuit 6 and undergoes the interpolation processing through the circuit 7 by means of the coefficient alpha. Thus the position of a scanning area is equivalently and finely adjusted for the effective picture element area of the element 2 so that the shake of a screen caused by the camera shake, etc., is corrected. Furthermore the circuit 9 controls a scanning pulse generating circuit 5 in accordance with the camera shake quantity to read the picture elements of the element 2 in the different ways accordingly to the coefficient alpha whether it is approximate to or far from 1/2. Therefore the coefficient alpha set by the circuit 7 is always far from 1/2 and the deterioration of image resolution can be suppressed for the reproduced images.

Title: Digital centerline filter
Inventor: DONARUDO EMU TAAGOFU
IPC: H03H17/02
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a centerline filter for filtering all pulse spectra except single lines. SOLUTION: The centerline filter for a radar receiver 50 is the cascade connection of an analog filter 54A and a digital filter 58A. A signal is passed through the filter 54A, and oversampled by an analog-to-digital converter 56A. A sharp cut-off FIR filter is used as the filter 58A to remove the residual undesired lines.
