The device includes a record paper conveying device which rotates around a record paper carrier body to convey a paper sheet around the carrier body by gripping the leading edge of the paper sheet. In this arrangement, the carrier body, against which a recording head abuts during a recording operation, is rotated following the movement of the paper sheet by a friction force between the platen part and the recording paper sheet. In one embodiment, the carrier body is stationary, and accordingly, the conveying speed of the record paper sheet is determined only by the drive speed of the conveying device so that the record paper sheet can be precisely conveyed.

Novel immunochemical assay reagents comprising combinations of (A) a carboxyl-containing water-soluble mono-olefinic polymeric compound combined with a hapten or its chemically modified product, or a hapten-supported latex resulting from the chemical linking of the hapten-bound polymeric compound to a polymeric latex, with (B) a hapten antibody, or a hapten antibody-supported carrier; and a method for immunochemically determining haptens by using the aforesaid reagent. This reagent is very stable and can be stored for an extended period of time without degradation. It enables transition from an agglutination inhibited pattern to an agglutinated pattern to be discerned clearly and rapidly with high sensitivity.

A fault recovery system of a ring network based on a synchronous transport module transmission system, having a fault data writing unit for writing, when an input fault is detected by a node, fault data in a predetermined user byte in an overhead of a frame flowing through both a working line and a protection line running in opposite directions to each other. By detecting the fault data in a supervision node or a node just before the fault position, the supervision node or the node just before the fault position executes a loopback operation.

An apparatus for printing video images is disclosed. First the percentage of backlighting or people in the image is detected. That is, the probability of the presence of backlighting or people is detected. Then, the density gradation table is modified based on the detection result, and the presence of backlighting or the presence of people in the image is evaluated based on optical information, to select the best density gradation table from among plural density gradation tables, or to synthesize the best density gradation table. A luminance table is generated using the optimized density gradation table, and gradation correction of the image is then accomplished using that luminance table.

A level difference of an upper pixel on an upper scanning line placed over an attentional pixel and a lower pixel on a lower scanning line placed under the attentional pixel, a level difference of the upper pixel and a lower left pixel, a level difference of the upper pixel and a lower right pixel, and a level difference of the lower pixel and an upper left pixel and a level difference of the lower pixel and an upper right pixel are derived. These level differences are compared with each other, and a line having a smallest level difference is detected and an effective interpolation line information is generated. Moreover, the level difference of the upper pixel and lower pixel is compared with the level difference of the upper right pixel and lower left pixel, and a smaller is set as a first interpolation line. In a similar manner, a second interpolation line is derived, and an ultimate interpolation line is selected from the first interpolation line, the second interpolation line and a line connecting the upper pixel and lower pixel on the basis of the effective interpolation line information.

The present invention discloses a missing pixels interpolating method and an apparatus using the method. The method forms a second image from a first image by interpolating a plurality of pixels constituting the first image with a plurality of first pseudo-pixels in such a way that they neighbor to the pixels diagonally and with a plurality of second pseudo-pixels in such a way that they neighbor to the pixels vertically and horizontally. The method comprises the first process of computing values of the first pseudo-pixels using a first monotonous increasing non-linear function, and the second process of computing values of the second pseudo-pixels using a second monotonous increasing non-linear function. The primary derived functions of the first and second monotonous increasing non-linear functions are upwards convex, the domains of definition of input values thereof are consistent with the respective ranges of mapping values, and only one input value other than the limits in each domain of definition is equal to its mapping value. The only one input value and the mapping value are the central neighborhood values of the domain of definition and the range, respectively.
摘要:
An image data processing apparatus for generating a font with contour lines expressed with gradations comprises a font ROM for storing a binary font data. An output port is provided for reading a target pixel with ambient pixels arranged in 3.times.3 matrix of the binary font data stored in the font ROM. A shift register produces an address data based on the binary data read from the font ROM. A look-up table has 2.sup.3.times.3 elements in which multilevel values in commensurate with the pixel patterns included the 3.times.3 matrix. One data of the multilevel data is output from the look-up table by designating one element by said address data, and is used as a gradation data of the target pixel. Thus, pixel of font can be expressed with a gradation, the jagged contour of the font is reduced.
