摘要： In a memory consolidated image processing LSI for reading data, a DRAM for storing image data for a plurality of page ranges which are formed by segmenting an image plane corresponding to a display screen in order to page-access a memory region of the DRAM, and image data for a plurality of word ranges which are formed by segmenting each of the page ranges in order to word-access the memory region, is consolidated with an image processing circuit. The size of each of the page ranges is set so that the multiplied value of the power consumption per pre-charge in a power consumption model of a memory by an average number of pre-charges is the substantially minimum value, and the size of each of the word ranges is set so that the multiplied value of the power consumption per word access in the power consumption model of the memory by an average number of word accesses is the substantially minimum value. Thus, it is possible to reduce the power consumption when a page access and a word access are carried out, so that the memory consolidated image processing LSI can be mounted on a portable image processing system.

摘要： A motion vector estimating system comprises a current image storing unit 1, a reference image storing unit 2, a motion vector estimating circuit 3 for estimating a motion of a current image in relation to a reference image, and a global motion vector estimating circuit 10. The global motion vector estimating circuit 10 comprises at least a feature setting part 11 for setting and recording a feature being a partial region distinguishable from other regions of a principle object in a picture, a feature-coordinates extracting part 12 for searching the current image for the feature to extract the coordinates of the feature, and a feature-coordinates storing part 13 for storing the coordinates of the feature. When the feature-coordinates extracting part 12 extracts the coordinates of the feature from the current image, the motion vector estimating system derives a difference between the feature coordinates stored in the storing part 13 and the extracted feature coordinates on the basis of a feature presence information outputted from the feature-coordinates extracting part 12, in order to estimate a global motion vector. When the feature-coordinates extracting part 12 has not could extract the feature, the motion vector estimating system carries out the usual motion vector estimation. Thus, in addition to the usual motion vector estimation, the presence and coordinates of a feature are extracted from the whole screen of a picture to detect a motion vector to retrieve a correct motion vector at the initial stage of the retrieval, so that it is possible to save the electric power and decrease the estimation time.

摘要： A motion vector estimating system prepares a predetermined range of a frame/field of image data as a macro block, selects a plurality of proposed motion vectors in the reference region, calculates a signal-strength difference between pixels corresponding to each of the proposed motion vectors of current and reference images. The system comprises: an accumulating element for deriving an accumulation result in parallel on the basis of the signal-strength difference by means of accumulating circuits connected in parallel as a pipeline; an accumulation stopping element having separate stop circuits for separately stopping the accumulation of the accumulating element every n accumulating circuits; and a control element for controlling the supply of the current image data and the reference image data for proposed motion vectors for each of the accumulating circuits, and for outputting a separate stop signal to the accumulation stopping element for stopping the accumulation for the proposed motion vector of the accumulating circuits immediately after the accumulated value of the absolute values of the differences between the signal values of picture elements of the current image and the reference image exceeds a predetermined value. Thus, it is possible to suitably omit unnecessary accumulation in a pipeline processing for estimating a motion vector, so that it is possible to increase the processing speed and to decrease the electric power consumption.
