A hand deviation correction device for correcting hand deviation components of an image. The hand deviation correction device includes a deflection detection unit for detecting the state of deflection, a deflection state discriminating unit for discriminating at least willful deflection and deflection by hand deviation, as deflection state, based on deflection detection signals from the deflection detection unit and a deflection correction signal outputting unit for calculating a deflection correction amount from the deflection state discrimination unit based on the deflection state discriminating signal from the deflection state discriminating unit for outputting a deflection correction signal. By discriminating the state of willful deflection, such as that caused by panning or tilting, from non-wilful deflection caused by hand deviation, the amount of correction corresponding to the state of deflection, that is, the zero correction mount for panning or tilting and a calculated value of the correction amount for deflection caused by hand deviation, may be used.

Hand deviation correction apparatus and video camera

The invention provides a video camera system such as a supervisory system wherein the amount of calculation for motion detection is reduced to reduce the required capacity for hardware. An output of a video camera is sent to a data processing apparatus. In the data processing apparatus, an evaluation value calculation block extracts a video signal of each of a plurality of areas and calculates an evaluation value of the image for each of the areas. Further, a microcomputer calculates a reference value based on the evaluation value obtained in an ordinary state and stores the reference value, and then compares the reference value with a current evaluation value to detect motion of the image. Further, the microcomputer controls the position of the video camera so that the area in which the motion has been detected may be positioned at a central portion of the field of view of the video camera.

Video camera system and automatic tracking method therefor

An apparatus for reproducing signals recorded on a selected one of first and second discs of different diameters, such as, a relatively large diameter video disc and a relatively small diameter compact disc, has a disc-transporting tray mounted for substantially horizontal movement between a first or operative position within a housing and a second or disc-inserting and withdrawing position in which the tray projects substantially forwardly from the housing through an opening at the front of the latter, the tray having first and second disc mounting portions dimensioned for receiving and holding the relatively large and small diameter discs, respectively, and the second or relatively small-diameter disc mounting portion being disposed at a front part of the tray and substantially contained within the confines of the first or large-diameter disc mounting portion for minimizing the required size of the tray, and hence the overall size of the apparatus. Further, access to the second or relatively small-diameter disc mounting portion of the tray for inserting or withdrawing a compact disc may be had when the tray is only partly projected from the housing, thereby to reduce the time required for loading and unloading or exchanging a compact disc.
