A picture recording apparatus which can record a picture on a write-once medium having an element which specifies a first size on a recording area assigned to data saving in edit processing, and an element which subtracts the first size from a remaining amount of recording area in the write-once medium to calculate a second size secured for recording, characterized in that a recording size is managed using the second size as an upper limit of a recordable size, and that an editing area is secured using the first size as a lower limit.

Picture recording apparatus

In an image recording/reproducing apparatus capable of handling a hard disk and an optical disk, when just-recording on the hard disk has been requested, if a residual recording capacity of the hard disk is more than a residual recording capacity of the optical disk that is in a non-recorded state, a compression encoding rate for image information is set by regarding the residual recording capacity of the hard disk as being equal to the residual recording capacity of the optical disk in the non-recorded state.

Image recording/reproducing apparatus and method

In a method of detecting motion vector data indicative of motion of a partial area in an input picture from any area on a reference picture, a first distortion between a partial area constructed by fields of the input picture and a partial area constructed by fields of the reference picture is calculated as a first evaluation value; a position of the partial area constructed by the fields of the reference picture at which the first evaluation value becomes the minimum value is detected; a search window on a frame of the reference picture is set on the basis of a detected position of the partial area constructed by the fields of the reference picture previously detected; and a second distortion between a partial area constructed by a frame in the set search window and a partial area constructed by a frame of the input picture is calculated as a second evaluation value, and a position of the partial area constructed by the frame of the reference picture at which the second evaluation value becomes the minimum value is detected. Therefore, the frame vectors can be detected on the basis of the field vector detection positions, so that the amount of calculations required to retrieve frame vectors can be reduced markedly, without degrading the detection precision of the frame vectors.
