    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.

    摘要： A method and apparatus for adaptively selecting a coding mode for video encoding systems using the techniques of predictive coding, interpolative coding, motion compensation, discrete cosine transformation (DCT), adaptive quantization, or variable length coding. In one system, a value related to an amount of total code, which is composed of current video code and its coding parameters for each of the above coding modes, is determined, respectively, and a coding mode corresponding to the smallest value is selected. Then, the encoding is performed using the selected coding mode.

    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： An image-taking apparatus generates an output image from a photographed image obtained by photographing and displays this output image on a display screen of a display section. The image-taking apparatus includes a recognition processing section for recognizing a specific subject (facial region of a person, or a facial component such as eyes) included in the photographed image. Referring to results of this recognition, the image-taking apparatus evaluates the dimension of the specific subject in each photographed image. If the dimension evaluated is relatively large, a relatively small magnification ratio to be employed upon the generation of the output image from the photographed image is provided. If the dimension evaluated is relatively small, a relatively large magnification ratio to be employed upon the generation of the output image from the photographed image is provided. As a result, the dimension of the specific subject in the output image is kept substantially constant.
