发明名称 Video camera apparatus
摘要 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</= alpha <X or (1-X)< alpha </=1 and X</= alpha </=(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.
