    Abstract: A movement vector detection apparatus has a detecting circuit for detecting a movement vector of an image with relation to a change amount of image density value in a determined time at an arbitrary position of the image and a space gradient of image signal at the arbitrary position, and a setting circuit for suitably setting a dimension and a shape of a unit operation area to output the movement vector in response to a space frequency of the input image.

    Abstract: A shakeproof camera includes a focus detection circuit for detecting a focus state from an image pickup signal output from an image pickup element, a luminance detection circuit for detecting a luminance from the image pickup signal, a shake detection circuit for detecting a shake vector of an image from the image pickup signal, and a control circuit for fetching outputs from the above detection circuits and performing focus control, exposure control, and shakeproof control. The detection circuits outputs the detection results during a vertical blanking period. The control circuit preferentially performs an arithmetic operation for shakeproof control on the basis of an output from the shake detection circuit and then performs other control operations.

    Abstract: The objective of the present invention is to provide a simple and accurate process for extracting an object from an image, which is used to impose a great load for an operator. According to the present invention, an image processing apparatus comprises an object extracting unit, for performing a predetermined process for image data for a position or an area that is designated and for extracting a specific object from an image, an outline part deciding unit, for selecting and authenticating an arbitrary segment of an outline obtained by the extracting unit, and an outline synthesis unit, for linking and synthesizing together the outline segments that are authenticated. Since a closed curve is formed by synthesizing the outline segments obtained by repeating the above process, and the outline of the object is thus determined, the outline segment that is extracted from the image and matches the correct outline of the object is sequentially selected and authenticated. The thus authenticated outline segments are linked and synthesized to gradually form the overall outline of the object.
