    • In an image processing method for obtaining a processed image signal from an original image signal representing an original image having a certain picture element density, a plurality of intermediate image signals which are different in frequency band are made on the basis of the original image signal. A plurality of transformed image signals are obtained by carrying out a transformation processing on the respective intermediate image signals on the basis of respective transformation functions, and a processed image signal is obtained from the transformed image signals. The transformation functions are defined by determining transformation function defining parameters for the transformation functions on the basis of the picture element density of the original image.

    • Output-size information G1 and reference-resolution information G0 are input to a zoom-rate section. The zoom-rate section derives zoom-rates M1 and M2, based on the output-size information G1 and the reference-resolution information G0. A reconstruction section reconstructs an image at the resolution level corresponding to the specified zoom-rate M1. A parameter-setting section derives an image-processing parameter K1 suitable for the resolution level of a reconstructed-image signal S1, based on the zoom-rate M1, reference-resolution information G0, and reference-processing parameter K0, and sets the derived parameter K1 to the image-processing section. The image-processing section obtains a processed-image signal S2 by performing image processing, using the image-processing parameter K1. A zoom-processing section performs a zoom process on the processed-image signal S2, using the zoom rate M2.

    • Band-limited image signals representing images, each of which is of one of different frequency bands, are formed from an original image signal representing an original image. A pixel vector at each of pixels in each of the band-limited images, which are represented by the band-limited image signals, is calculated. A noise component and an edge component of each of the band-limited images are separated in accordance with the calculated pixel vector. Smoothing processing for the noise component and/or enhancement processing for the edge component is performed on each of the band-limited image signals to obtain a processed band-limited image signal. A processed image signal is then obtained in accordance with the thus obtained processed band-limited image signals. The image processing is thus performed such that noise components contained in the image become imperceptible, and such that a structure pattern contained in the image becomes perceptible.
    • 由表示原始图像的原始图像信号形成代表图像的频带限制图像信号,每个频带是不同频带之一。 计算由频带限制图像信号表示的每个频带限制图像中的每个像素处的像素矢量。 每个带限图像的噪声分量和边缘分量根据所计算的像素矢量被分离。 对每个带限图像信号执行用于边缘分量的噪声分量和/或增强处理的平滑处理以获得经处理的带限图像信号。 然后根据由此获得的经处理的带限图像信号获得经处理的图像信号。 因此,执行图像处理,使得包含在图像中的噪声分量变得不可察觉,并且使得包含在图像中的结构图案变得可察觉。

    • A developing apparatus, an image formation apparatus and a process cartridge is provided. Even though the sealing materials of the initial developer container are stripped off in such a way that the process cartridge having the developing apparatus is tilted, the initial developer can be uniformly supplied along the central axis line of the developer carrier. The developing apparatus performs a self toner control and has an initial developer case 10 for containing the non-used initial developer 3c that is input into the developer containing space S. The initial developer case 10 is divided internally into a plurality of partition spaces 10b along the direction of the central axial line D of the developing sleeve 4, so that a plurality of partitions 10c is formed inside the initial developer case 10. Based on the opening 10a for inputting the initial developer, the partition surface F facing to the partition space 10b of each partition 10c is tilted from an imaginary plane G perpendicular to the central axial line D of the developing sleeve 4 toward one end H along the direction of the central axial line D of the developing sleeve 4.
