Abstract: An information processing apparatus having first and second buses, includes: a read/write command unit transmitting a read command or a write command to the first bus; a read command unit receiving a read command from the second bus; a write command unit receiving a write command from the second bus; and a command unit transmit the read command and the write command to the read/write command unit based on the read and write commands received by the read command unit and the write command unit. Further, the command unit stops transmitting the read command, and, while stopping transmission of the read command, change a transmission order of the read and the write commands so that the read/write command unit transmits the write command with higher priority than the read command.

Abstract: A CPU determines whether the intended use of the image data to be stored in a plurality of HDDs has a first-type purpose, which requires storing temporarily stored image data for carrying out output processing of the image data, or a second-type purpose, which requires long-term preservation of the image data. If the first-type intended use is determined, a first-type mode for saving is selected, wherein the image data to be stored are divided and each divided set of image data is stored into one HDD. If the second-type intended use is determined, a second-type mode for saving is selected, wherein the same image data part is saved in a plurality of storage means.

Abstract: In a digital copier which allow the quality of an output image to be adjusted in a plurality of levels, a scanner reads a document image and generates corresponding image data. An analog-to-digital converter transforms the image data to a pixel-by-pixel electric signal. The electric signal is written to an image memory. An image processing section reads a particular portion of the image (e.g. one-fifth in the subscanning direction) out of the memory repeatedly, while changing density each time. The results of such processing are sent to a recording section and printed on a single paper as a combined image. As a result, partial images representative of a particular density each are printed on a single paper. This not only promotes easy evaluation but also saves papers.

Abstract: An image processing apparatus for image compression and decompression in which occurrence of moire in a reconstructed image is eliminated. The apparatus includes an encoder part for encoding an image into a compressed image, and a decoder part for decoding the compressed image into a reconstructed image. The encoder part includes an input part, a predictive coder, a subtracter, an ADCT encoder and a code memory. The predictive coder and subtracter act to remove high-frequency components prior to the calculation of the DCT coefficients by the ADCT encoder, thereby preventing moire in the reconstructed image.

Abstract: An image processing apparatus in which a moire occurring in a half tone area can be eliminated by a suitable filter. A plurality of data blocks comprising N*N pixel data are transformed by means of a two-dimensional orthogonal transform so as to obtain an N*N matrix transformation factor block. An evaluation block is prepared which comprises N*N transformation factors each of which is the mean value of the absolute values of corresponding factors from a data block being considered and data blocks surrounding the data block to be determined. Mean values A[i] and B[i] (i=0 to L-1) of predetermined transformation factors are calculated, A[i] being mean values of factors included in a number L of first areas consecutively positioned along a diagonal line of the evaluation block, B[i] being mean values of factors included in a number L of second areas positioned adjacent to and lower in frequency to the corresponding first areas.
