摘要： Disclosed is a method for controlling the shapes of FM-AM mixed halftone dots on the multi-bit depth imaging apparatus. In the prior art, since the reproduction of the shapes of the dots in various gradations is absolutely based on the theory of random error diffusion and is influenced by the dynamic controlling output mechanism for the multi-bit dots, it is hard to assure the controllability of the shapes of the dots in a certain gradation. Based on the prior art, the dynamic statistic algorithm with adjacent output gray levels is introduced to assure the controllability of the shapes of the dots and solve the problem of random change of the shapes of the dots due to the randomicity of the error diffusion. According to the disclosed method, the features of the multi-bit imaging apparatus can be achieved fully in light of the requirements of the dots on the basis of the original method for multi-bit FM-AM mixed screening using error diffusion based on dual-feedback. The effect of FM-AM mixed halftone screening can be achieved under low resolution with controllable shapes of the dots. The problem of granular sensation can be solved during the practical output of the mixed halftone dots so as to assure the smooth effect of the gradations.

摘要： Disclosed is a method for processing FM-AM mixed halftone images on a multi-bit depth imaging apparatus, which relates to a method for producing halftone dots in the field of image hard copying. In the prior art, since it is hard to avoid the impact of the error diffusion for the output apparatus to control the mixed dots with multi-bit imaging depth based on the error diffusion, the output of the mixed dots with multi-bit imaging depth cannot satisfy requirements of the apparatus. According to the method of the present invention, the dynamic algorithm for controlling the multi-bit mixed dots is used for screening based on the existing mixed screening process using dual-feedback error diffusion. Furthermore, multi-bit halftone images with high quality and rich gradations can be output by the multi-bit depth imaging apparatus. The method of the present invention can solve the phenomenon of sawtooth in the margins of the mixed dots output by the conventional single-bit apparatus and obtain the FM-AM mixed dots with the effect of high resolution and continuous gradations, which are output under low resolution.

摘要： Fault tolerance may be achieved in a branched optical communication system such that a fault in one optical path may not affect optical signals coupled from a healthy optical path. In general, a flexible branching unit is configured, when adding and dropping channels, to select channels from a healthy path and not from the faulty path (e.g., a trunk path or a branch path) to prevent non-uniform channel loading on the trunk path after the branching unit. In this manner, a fault detected on the trunk path may not affect signals from the branch path and a fault detected on the branch path may not affect signals from the trunk path, thereby providing fault tolerance. A flexible branching unit may also be capable of adjusting the number and selection of channels that are added and dropped at the branching unit.
