Abstract
The present invention relates to a video camera apparatus which can automatically correct an image vibration, such as a handling or the like electronically. A control circuit changes an interpolation coefficient .alpha. of an interpolation processing circuit in response to a detected output from a vibration detecting apparatus or an output from a motion vector calculating apparatus that detects a vibration of a video signal. Also, the control circuit controls a scanning pulse generating circuit that derives a scanning pulse for scanning the imager. The scanning pulse generating circuit changes a combination of two scanning lines that are to be interpolated by the interpolation processing circuit using the interpolation coefficient .alpha. by changing the scanning state of the imager when 0.ltoreq..alpha.<X or (1-X)<.alpha..ltoreq.1 and X.ltoreq..alpha..ltoreq.(1-X) if X is a limited value of the interpolation coefficient .alpha. and the limited value X is a value smaller than 1/2. Thus, a resolution of a reproduced picture based on the video signal thus obtained by the above interpolation processing can be prevented from being deteriorated.
