摘要:
The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is open to a user, the received data is deciphered by a 1394 interface. In contrast, in the personal computer with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key by a 1394 interface, and a result of the decipherment is further deciphered using a session key by an application section.

A laser mark which will be the positioning mark for a secondary charged particle image in the charged particle beam apparatus is applied by moving the sample processing/observation area in the charged particle beam apparatus so as to come into the view field while performing an observation by an infrared microscope, and by a using a laser optical system disposed coaxially with an optical observation system, the mark made at the periphery of the processing/observation object area. Next, by a superposition of an infrared transmission image and a CAD data, the processing/observation object area and the laser mark are registered onto the CAD data. And, by a correlation of the registered data read from the charged particle beam apparatus and the secondary charged particle image, it is possible to accurately and easily determine the processing position.

摘要:
Obtains an image from which noise is removed upon compressing or decoding and displaying an image containing noise. To accomplish this, a subband to which a wavelet transform coefficient of interest belongs is checked upon entropy decoding, and when the coefficient belongs to a subband other than LL, decoding is aborted at a predetermined lower-limit bit plane, and all bits contained in bit planes from the lower-limit bit plane to the least significant bit plane are set at zero.

In order to eliminate noise from an X-ray image by obtaining transform coefficients of a wavelet transform based upon information contained in tile-by-tile image data and obtaining image data based upon these transform coefficients, the entirety of a pre-processed original image is segmented into a plurality of tiles (S301). Wavelet transform coefficients of each tile obtained by segmentation are output (S302). Each tile is subjected to texture analysis and the results of analysis are output (S303). Next, a coefficient conversion is applied to the wavelet transform coefficients of each tile based upon the results of analysis (S304). High-frequency components among the transform coefficients are subjected to coefficient conversion. Next, an inverse discrete wavelet transform is applied to the wavelet transform coefficients of each area that has undergone conversion, whereby an image from which noise has been eliminated is output (S306).

The present invention provides a portable electronic device including an operator block, a display block, detection means, and control means. The operation block has a plurality of operation buttons arranged in matrix. The display block, arranged in the vicinity of the operator block, is capable of displaying a screen divided into a plurality of areas corresponding to the arrangement of the plurality of operation buttons, displaying a cursor for selecting each the areas, and entering the selection by operation of each of the operation buttons. The detection means detects whether any one of the plurality of operation buttons has been operated. The control means positions the cursor to the area corresponding to the detected operation button and displays the cursor on the display block.

A matrix switch of an optical waveguide type which has low transmission loss variations and includes uniform grooves with a deep vertical cross section is provided. A switching part for selecting between a light path extending from an input port of a first set of optical waveguides 111-11m to an output port of the first set of optical waveguides 111-11m and a light path extending from an input port of the first set of optical waveguides 111-11m to an output port of a second set of optical waveguides 121-12n is arranged for insertion into a switching groove arranged at each of the intersections of the first set of optical waveguides 111-11m and the second set of optical waveguides 121-12n. Each of the switching grooves is arranged on an imaginary straight line connecting intersections of the first set of optical waveguides 111-11m and the second set of optical waveguides 121-12n.

A recording/reproducing medium having grooves, a land formed between the grooves, and land prepits formed on the land in which each of said land prepits has a most optimum design condition where a ratio (LLP Level/offset) between a voltage amplitude (LLP Level) of a land prepit detection signal and an offset level (offset) of an RF signal becomes more than about or where an amplitude change of an RF signal through the land prepit becomes minimum. The recording/reproducing medium can be one of a DVD-R and a DVD-RW.

A DTV operating screen is displayed on the CRT display screen of a DTV which is the controlling apparatus of a network. In the event that the user selects the DVHS from the buttons displayed on the DTV operating screen, data corresponding to the DVHS operation screen is input to the DTV, and a DVHS operation screen is displayed on the CRT display screen 61. The user operation executed regarding the DVHS operation screen are notified from the DTV to the DVHS, so the DTV can execute control corresponding to the operations of the user, without transmitting commands for directly controlling the DVHS.
