摘要： An imaging device includes: an imaging element which outputs a signal based on an optical image projected to the imaging element by imaging; a correction lens which moves the optical image on the imaging element; a face detection unit which detects a person's face as an object from a judgment image based on the output signal from the imaging element and detects the position and the direction of the face in the judgment image; and an imaging control unit which controls the position of the correction lens in accordance with the position and the direction of the detected face. A layout-adjusted image is generated from the output signal from the imaging element after the control. More specifically, the position of the correction lens is controlled so as to obtain a layout-adjusted image of the golden cut when an attention is paid on the face position. Moreover, the position of the correction lens is controlled so as to increase the space in the direction in which the face is directed.

摘要： A motion vector detecting circuit and a motion video compressing system are disclosed. The detecting circuit detect a vector which direct from a spatial location of a current macroblock to a spatial location of a reference macroblock. The detecting circuit includes a first extracting circuit, a second extracting circuit and a searching circuit. The first extracting circuit extracts upper bits from each pixel data of the current macroblock. The second extracting circuit extracts upper bits from each pixel data of the reference frame. The searching circuit searches the upper-bits-extracted reference frame for a macroblock having the strongest correlation with the current macroblock by comparing the upper-bits-extracted current macroblock with the upper-bits-extracted reference frame and outputs the spatial location of the reference macroblock. The motion video compressing system includes the motion vector detecting circuit, a transform-coding circuit, a subtracter, a comparator and a controller. The transform-coding circuit codes inputted data into compressed. The subtracter calculates a difference between each pixel data of the current macroblock and each corresponding pixel data of the reference macroblock directed by the motion vector. The comparator compares an amount of data being obtained by the transform-coding the current macroblock with an amount of data being obtained by the transform-coding the differential macroblock. The controller controls the transform-coding circuit such that the transform-coding circuit outputs which of the compressed current macroblock and the compressed differential macroblock has a smaller amount of data.

摘要： A method is disclosed, for encoding a signal with a three dimensional image sequence using a series of left and right images. Each image in the left image series is a picture formed by non-interlaced or interlaced scanned left line images, and each image in the right image series is a picture formed by non-interlaced or interlaced scanned right line images. The left line images contained in the left picture are merged with the right line images contained in the right picture to produce an alternately arranged left and right line merged picture. The merged picture is encoded using an MPEG-2 compliant encoder.

摘要： A decoding start controller is capable of appropriately decoding pictures up to the final picture, even if the amount of the data stored in a bit-stream buffer is reduced, as a result of partial storage of the data in an internal local buffer. Further, the decoding start controller is capable of decoding extremely short bit-stream data. If completion information, which is sent from an input side of the bit-stream data and represents completion of input of the bit-stream data, is detected, a decoding start instruction signal is output to a variable-length decoder regardless of a value of VBV occupancy. In short, when the amount of the data stored in the bit-stream buffer connected to the decoder having the decoding start controller, is equal or greater than the value of VBV occupancy, the decoding start instruction signal will usually be sent to the variable-length decoder: namely, so-called decoding start control operation based on value of VBV occupancy. If the completion information is detected, the decoding start control operation based on the value of VBV occupancy is interrupted, and the decoding start instruction signal is output.
