Abstract:
Waveform equalization is carried out for a reproduction signal of a test signal recorded with data in each unit recording area of a recording medium by an adaptive type waveform equalization means while a tap coefficient is changed, and a tap coefficient at the time when the equalization signal approaches most closely to an ideal equalization signal is used as an optimum tap coefficient. The reproduction signal of data in each unit recording area is subjected to waveform equalization by using this optimum tap coefficient. In this way, a data reproduction apparatus can be obtained which can effect waveform equalization of data stably, reliably and quickly and can accomplish high density recording by a small scale circuit.

Abstract:
A position detecting section (20) detects the position of the viewpoint of the operator based on the output of the bisected light beam photodetector (2) of an eyeball movement measuring instrument. A position processing section (21) determines the central position of the vicinity area of the viewpoint based on the information from the section (20), and a size processing section (23) determines the size of the vicinity area based on the output of a lever (18) for changing the size. Video signals (10) are inputted to a code quantity reducing section (13) after the signals are encoded by means of a compressing section. A system control section (30) reduces the code quantity by controlling the section (13) so that the code quantity assigned to the other area than the vicinity area is smaller than the code quantity assigned to the vicinity area. Therefore, image data are encoded and compressed in real time in a limited code quantity and, at the same time, images having image qualities which are visually improved as high as possible to the user can be obtained at the time of encoding the image data.
Abstract:
A game machine system which is provided with a set top box (51) which is a receiver means that receives digital data distributed by utilizing a broadcasting system or communication system. A game machine (52) is inhibited from starting up a game software until the machine receives a software actuation allowance signal through the receiver means. Following the software actuation allowance signal, data with which part of data of the game software are replaced or data to be inserted into the software are sent. The data can be used as a commercial advertisement. Therefore, the game machine (52) judges whether or not a commercial advertisement is contained in the software. When no commercial advertisement is contained, the machine (52) is adapted not to be operated.

A shadow closer to reality is added to an object image with a high speed with a simple construction and simple processings. A shadow video signal V4 and a shadow key signal K4 are generated by a shadow signal generating unit (20) and the shadow key signal K4 is inputted to a real shadow signal generator (50), which generates a real shadow key by which a more realistic shadow is generated.
Abstract:
Transmitted light through a film which is obtained by applying projected light to an image information recording region of the film is directed to a photoelectric conversion means to acquire the image information by the photoelectric conversion. A deflecting means which deflects the transmitted light is provided. A 1st group of image information is acquired by the photoelectric conversion of the 1st transmitted light which is the transmitted light before the deflection by the deflecting means and is transmitted through a 1st recording region in the recording region. A 2nd group of image information is acquired by the photoelectric conversion of the 2nd transmitted light which is the transmitted light after the deflection by the deflecting means and is transmitted through a 2nd recording region in the recording region. The 1st image information group and the 2nd image information group are combined to generate synthesized image information. Thus a high resolution image acquisition device by which the high resolution image information can be acquired from the film with a simple construction can be realized.
Abstract:
The characteristic of nonlinear processing of image data are designated by means of a GUI and the processing results are immediately displayed. A personal computer (72) displays a GUI image for input on a monitor. When a user designates a nonlinear characteristic through an input device (70), the computer (72) extracts a polygonal line function representing the nonlinear characteristic and displays the function in the GUI image. In addition, the computer (72) generates a program used when a linear array type multiple-parallel processor (DSP80) executes the nonlinear processing specified by the extracted polygonal line function and downloads the program in the processor (DSP80).

A generator which comprises a 3-phase AC generator (11) that has a stator (38) arranged circumferentially around the rotating shaft (32) and a rotor (35) secured to the rotating shaft (32) and having an annular portion surrounding the outer circumference of the stator (38) and a manual rotary drive mechanism which includes a speed increase portion (13) in mesh with the gear (33) secured to the rotating shaft (32) and a manual rotary drive portion (12) engaged with the speed increase portion (13) and which drives the rotor (35) of the 3-phase AC generator (11) through the speed increase portion (13) and the gear (33) by the rotation of the manual rotary drive portion (12) to cause the 3-phase AC generator (11) to generate electricity. The diameter of the gear (33) mounted on the rotating shaft (32) of the 3-phase AC generator (11) is set larger than the diameter of the rotating shaft (32) and smaller than the diameter of the annular portion of the rotor (35).
Abstract:
A DAB receiver which facilitates program selection. The receiver is provided with a data table (31) on which sets of service IDs and time data indicating the serial programs are listed in the order of the broadcasting time and a data table (32) on which the programs are listed in the order of the dialing frequency of the programs. When the receiver is operated for selecting a program, whether or not the data which are coincident with the service ID of the program at the latest broadcasting time on the table (31) exist on the table (32) is checked. When the data exist on the table (32), the program of the service ID is selected. When the data do not exist on the table (32), another program is selected by repeating the same procedure on the service ID of the program at the next latest broadcasting time on the data listed on the table (31).
Abstract:
A clock generating apparatus applicable to a sample servo type magnetic disk. A clock pattern regenerative signal z(t) is digitized by an A/D converter (33), and the resultant signal is supplied to a phase comparator (52). The linear coupling of N-pieces of sample values and N-pieces of weighting coefficients is subjected to inner product computation in a computing element (61) to obtain a phase comparison error signal f( theta ) from a D flip-flop (62). This signal f( theta ) is analoged in a D/A converter (53), and the resultant signal is supplied as a control signal to VCO (51) via a loop filter (54), the phase of a clock signal CLK from the VCO (51) being controlled to obtain a clock signal CLK synchronous with the regenerative signal z(t). When coefficients the sum of which becomes zero are used as weighting coefficients, a signal f( theta ) not influenced by DC component on which the regenerative signal z(t) is superposed, can be obtained, and a clock signal CLK synchronized with a high accurancy with the regenerative signal z(t) can be obtained.
