摘要： An image area extracting method for extracting the desired areas from the image accurately and efficiently. The rough boundary area, in which the boundary area is roughly assigned between the desired area and areas other than the desired area, is divided into a plurality of small areas. The area extracting procedure is executed on each small area and the desired area and areas other than the desired area are detected from each small area. The boundary area mask image is formed based on the detection result and the desired area is extracted based on the boundary area mask image. Thus, the desired area can be extracted from the image accurately and efficiently.

摘要： An apparatus and a method for generating time-series data, an apparatus and a method for editing curves and a recording medium having a recorded program in which the corresponding relation between curves at different time junctures is obtained from given corresponding points such as to prevent the curve shape from becoming dull due to smoothing. A candidate point string extraction unit checks the relation between the input point coordinate and the corresponding relation information to set each group of input points having the corresponding relation as a corresponding point string. An interpolation curve generating unit calculates an interpolation curve C(t) interpolating the corresponding point string along the time axis. An extraction time juncture extraction unit extracts the extraction time junctures ts of the corresponding point string for which the corresponding points are not acquired and calculates the curve I2(t) at the extraction time junctures ts and the passage position C(ts) of the interpolation curve I2(ts). The corresponding point calculating unit 105 calculates the corresponding point P(ts) at the extraction time juncture ts from the curve I2(t) and the passage position C(ts) of the interpolation curve I2(ts). A curve editing device is also provided by employing this time-series data generating device.

摘要： In this invention, when the portion from which a key signal .alpha. is to be generated of picture is caused to be foreground F, the portion except for the above is caused to be background B, and pixel value of pixels constituting that picture is designated at C, the key signal .alpha. is generated so as to satisfy the relational expression C'=(F-B).alpha.'('(prime) represents differentiation). In more practical sense, a change detecting section 10 calculates change C' of pixel value between pixels constituting picture, and an F-B detecting section 30 calculates difference F-B between the foreground and the background. In addition, an integral value calculating section 40 divides the change C' by the difference F-B to integrate the result obtained by divisional operation to thereby determine key signal .alpha.. As a result, precise key signal can be obtained in this invention.
