摘要:
In an image coding apparatus for encoding and decoding multi-level image data with block truncation coding, multi-level image data is divided into second blocks (e.g., 6*6 pixels) which is larger in size than a first block (e.g., 4*4 pixels) to be coded. Average value and gradation level amplitude are calculated on a second block, and encoding and decoding are performed on a first block by using the average value and gradation level amplitude. When a pixel not adjacent to the first block is included in an end of the image or the like in a second block, data of the actual pixels are used for the pixels having no data. Thus, deterioration of the image quality can be reduced.

In a system for variable-length coding, when image data of a plurality of documents are compressed and stored in a compression memory, the image data is divided into a plurality of areas. Then, attributes are discriminated for each area, and the result of the attribute discrimination is written to an attribute memory. Attribute counters count the numbers of the discriminated attributes. A variable-length compression section compresses the code data with a compression method in response to the attribute data written to the attribute memory, and the compressed data is written to a compression memory.

In an image processor, after the background of input image data is removed, the image data are divided into a plurality of areas, and the attribute of image is discriminated for each area. The image data after the background removal is compressed according to the result of attribute discrimination. The amount of the background removal can be controlled. Preferably, the amount of the background removal is controlled according to the discriminated attribute. Then, the background can be removed without artificial feeling in a reproduced image.

The amount in offset of toner or the like is used to determine two points sandwiching lattice points of input data and divide the region between the two points equally in N−1. The output values at the two points and each point equally dividing the region are obtained to calculate gradients m1-m8 between any two adjacent ones of the points. Then, difference values dm1-dm7 in gradient between any two adjacent ones of the straight lines are calculated and (N−1) lattice points serving as dividing points are selected from the difference values in descending order. It should be noted that N is smaller than M. Then, the input and output values of the determined (N+1) lattice points N0-N4 are plotted and they are bounded by straight line and thus plotted to linearly interpolate the output data for the input data. Thus, an image processing apparatus can be provided capable of precisely modifying output images with reduced memory capacity.

A pixel interpolating device using the IM-GPDCT method and capable of preventing noise generation divides an original image into a plurality of blocks and picks up a block to be processed as a target block. Further, an image peripheral to the target block is extracted as a peripheral image. By using the peripheral image as an extension region, DCT transform is carried out. Thereafter, the peripheral image is magnified, and the IM-GPDCT processing is carried by using the magnified image.

An action figure fabrication toy in which a preselected action figure torso is placed in the center of the toy and individual body parts for the action figure are then placed in separate chambers arranged circumferentially about the center on opposite sides. The toy is then activated and one body part from each chamber is selected and automatically attached to the preselected torso, in order to form a composite action figure comprised of the torso and each of the selected body parts from each of the separate chambers.

The present invention provides a technique for eliminating the effect of the thermal drift and other variances and to improve the observing or manipulating accuracy of a scanning probe microscope or atom manipulator by using the technique to correct the aforementioned change in the relative position of the probe and the sample due to heat or other factors during the observation or manipulation. To obtain an image of the sample surface at the atomic level or perform a certain manipulation on an atom on the sample surface, the present invention can be applied to a probe position control method for controlling the relative position of the probe and the sample while measuring an interaction between the objective atom on the sample surface and the tip of the probe. In the present method, the relative position of the probe and the sample are changed while the probe is oscillated relative to the sample in two directions parallel to the sample surface at frequencies of f1 and f2 (S1a). Meanwhile, a point (or characteristic point) where the frequencies f1 and f2 disappear from the measured value of the interaction working in the direction perpendicular to the sample surface is detected (S1b). Then, the relative movement of the probe and the sample is controlled so that the measurement value thereby detected is maintained (i.e. the characteristic point is tracked; S1c), and the speed of the aforementioned relative movement is determined (S1d). Subsequently, the relative position control is corrected using the detected speed (S2).

A compressor is provided for guiding lubricating oil separated from the discharged refrigerant by an oil separator to a radial bearing supporting a drive shaft through an oil supply hole. A rotating member that rotates together with the drive shaft is provided adjacent to the radial bearing on the drive shaft, and lubricating oil is supplied to the radial bearing via a gap between an external surface of the rotating member and an internal surface of a circular hole that supports the rotating member. An oil support groove, which alternately communicates with the oil supply hole and the discharge hole every time the rotating member rotates once, is provided on the external surface of the rotating member, and the lubricating oil flowing in from the oil supply hole is intermittently discharged into a drive chamber via the groove and the discharge hole.
