摘要： A system of detecting a motion vector for an object block in a current frame of an orthogonally transformed video with respect to a stored reference frame. The motion victor is detected by: extracting a predetermined pattern of lower frequency components from the object block; orthogonally inverse transform the extracted lower frequency components within the pattern to yield the pattern of pixel data; searching the reference frame for a block having a maximum correlation with the pattern of pixel data; and calculating the motion vector from the object block to the block having a maximum correlation. As an orthogonal transform, DCT (discrete cosine transform) is preferable. Creating a row and a column image comprising sums obtained by adding all the pixels in each column and each row of the object block and applying the above searching and calculating process to the row and the column image enables the motion vector detection from a normal or noncompressed video.

摘要： The method involves performing intra frame coding of a non-compressed picture frame to produce one compresses picture frame which is then decoded to produce one reference picture frame. Inter frame coding is performed between the non-compresses picture frame and another reference picture frame to produce another compressed picture frame (615). The frame (615) is decoded to produce a third reference picture frame. An independent claim is also included for a stepwise image quality complementary type coding apparatus.

摘要： A video signai conversion apparatus converts DV-format encoded compressed video data to MPEG format data, by utilizing motion flag information contained in the DV data which specifies for each of respective DCT blocks whether interlaced-frame mode DCT processing or progressive-field mode DCT processing has been applied to the block when executing DV encoding. The motion flag information can be used by a procesing mode selection section (16) to determine various MPEG encoding modes to be applied in units of MPEG macroblocks, such as selecting respective macroblocks to be subjected to interlaced-frame mode DCT processing by an orthogonal transform processing section (17) when the set of motion flags corresponding to the blocks constituting that macroblock are judged to indicate no substantial amount of motion for the macroblock, and to select progressive-field mode DCT processing when a substantial amount of motion is judged to exist. The amount of MPEG processing can thereby be readily reduced, without deterioration of image quality.
摘要翻译： 视频签名转换装置通过利用包含在DV数据中的运动标志信息将DV格式编码的压缩视频数据转换为MPEG格式的数据，该运动标志信息为每个DCT块指定是否隔行帧模式DCT处理或逐行场模式DCT处理 在执行DV编码时已被应用于块。 运动标志信息可以由处理模式选择部分（16）使用，以确定要以MPEG宏块为单位应用的各种MPEG编码模式，诸如通过正交变换来选择要进行隔行帧模式DCT处理的相应宏块 处理部分（17）当判定与构成该宏块的块相对应的运动标志的集合指示不存在宏块的实质运动量时，并且当判断存在大量的运动时选择逐行场模式DCT处理 。 因此可以容易地减少MPEG处理的量，而不会降低图像质量。
