    摘要: 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. A filter selection signal is generated which corresponds to the number i when a condition is satisfied where A[i]>B[i] and A[i]>threshold value th1. The pixel data corresponding to the evaluation block is smoothed by the selected filter.

    摘要: An apparatus includes a function control device to provide a specific function to the apparatus, a network control device to control communication between the apparatus and other apparatus via a network, and a main control device to control operation of the apparatus. The network control device operates while communication with the function control device is being cut off when the function control device is not supplied with power, The function control device includes a user circuit to detect restarting of a power supply to the function control device, and establish communication with the network control device in response to detection of restarting of the power supply to the function control device. The main control device controls communication between the apparatus and the other apparatus, through communication established between the main control device and the function control device and communication established between the function control device and the network control device.

    摘要: An image area discriminating method surely distinguishes a character image area and a halftone image area printed on a single document in response to image data outputted by an image reader. An image of interest is divided into N.times.N blocks and subjected to two-dimensional orthogonal transform block by block to produce an N.times.N coefficient pattern. The blocks each is compared with coefficient patterns prepared beforehand and matching the characteristics of character images to see if the block lies in a character image area or in a halftone image area. The N.times.N coefficients may be replaced with N.times.N vectors. Then, a necessary number of vectors are selected out of the N.times.N vectors to generate a .upsilon.-dimensional coefficient vector, and it is compared with vecotrs prepared beforehand for character identification and matching the characteristics of character images.

    摘要: In a data processing apparatus of the present invention, a disk unit storing a disk is mounted on the apparatus such that the surface of the disk is parallel to the direction of a shock or an impact. This protects the disk unit and therefore the disk from the influence of shocks and impacts as far as possible.
