Abstract: In order to provide a noise removal method for removing noise signals mixed into an image signal without deteriorating picture quality of the overall image, such zigzag noise signals that the difference between the output levels of two pixels adjacent to each other along a noise generation direction alternately takes positive and negative vales at least three times are detected from noise signals mixed into an image signal. Then, a specific pixel is noted among a plurality of pixels corresponding to the noise signals, for calculating a mean value of the output levels of the noise signals with reference to the specific pixel and correcting the output level of a noise signal corresponding to the said specific pixel with the said mean value.

Abstract: OSD data YD includes a color designating signal As and a color changing signal Ex. When a color register number is designated by the color designating signal As, a color storage unit 41 outputs an appropriate color signal. A Y signal is branched from the outputted color signal and subjected to a modulating process by the color changing signal Ex. The Y changing signal obtained by the modulating process is merged with a Cb signal and a Cr signal so as to form new color signal. The OSD data YD with changed color is subjected to a synthesizing process with image data XD according to the predetermined mixture ratio.

Abstract: It is an object of the present invention to prevent an image distortion from occurring by using a line memory of small memory capacity. For example, an image is decomposed into strip regions 12, and each strip region 12 is filtered together with certain excess data 14 from a neighboring strip region 12 to prevent an image distortion from occurring at the boundary between the strip regions 12 while executing band decomposition on the strip region 12 which is smaller in size than the entire image with a smaller line memory. In the band decomposition, a line memory which supports band decomposition of, for example, 3 decomposition levels is repeatedly and recursively used, whereby band decomposition of deeper decomposition levels is executed without any problems. In this manner, line-based wavelet transform for deeper decomposition levels is executed with a small line memory. Also reverse wavelet transform is executed in the similar manner.

Abstract: A lock structure of a spherical bearing restrains an outer race from turning relative to a housing with a simple structure. It is provided with protruding portions formed on a periphery of one side of a bearing hole of the housing. A flange is formed on one side of the outer race. Meanwhile notches (engagement portions) are formed in the flange, which are brought into engagement with the protruding portions. An annular V-shaped groove (staking groove) formed in the other side of the outer race is staked. With such a simplified structure, the spherical bearing can be locked to the housing while being restrained from turning relative thereto.

Abstract: A rolling bearing and a rod end bearing are provided with a tilt mechanism and a rotary mechanism that are mutually independent. The tilt mechanism has a non-lubricated type spherical sliding bearing structure. The rotary mechanism has a rolling bearing structure which may or may not be sealed. By means of the non-lubricated type spherical sliding bearing structure, a tilt of the shaft center is made possible, and by means of a sealed rolling bearing structure, problems such as a lubrication oil leak are avoided, and carrying out high speed rotation and continuous rotation become possible. Because the sealed rolling bearing structure of the rotary mechanism does not call for a shaft center tilt function at all, the material of the seal can be chosen such that it emphasizes sliding resistance and high durability.

Abstract: An object of the present invention is to reduce bit depth and word number of a LUT memory 12 as small as possible, while obtaining &ggr; conversion output data with accuracy superior to the bit depth. Outputting table output data Dout0 and Dout1 which are associated with first table input data RA0 addressed and inputted to the LUT memory 12 and second table input data RA1 obtained by adding “1” thereto, and interpolating them outside the LUT memory 12, thereby obtaining output data having a larger bit depth than the LUT memory 12. At this time, the speed of signal processing is improved by employing a dual port memory as the LUT memory 12 or using a register group for the single port memory. Also, when the second table input data RA1 overflows, a specific value is employed as an alternative.

Abstract: A memory control circuit includes a controller (1A) for controlling a RAM (13) conforming to the standard where source voltage is 2.5 V (SSTL2 standard), and a nonvolatile memory (14) conforming to the standard where source voltage is 3.3 V (LVTTL standard) via a control bus (10) and data buses (11, 12). The control bus (10) for transmitting an address signal and a control signal is shared by these memories (13, 14).

The number of signal lines can be reduced, and it is possible to prevent signals at high voltage level outputted from the nonvolatile memory (14) from being applied to the RAM (13) driven at low voltages, to cause an occurrence of malfunction at the RAM (13).

Abstract: A broadcast program is contiguously stored to a real-time storage means in a program server. The stored program is read from the real-time storage means and sent to a receiver when the receiver sends a request to the program server to send the stored program to the receiver so that the receiver may show the stored program. Retrieval of the stored program is similar to replaying a program stored on a video tape recorder.

Abstract: An image conversion device is provided with a first buffer area for storing either one of even field and odd field of inputted dot sequential data and a second buffer area for storing the other thereof. A data transfer control circuit controls in such a manner that, during a period in which one of the two fields is written in the first buffer area, the other field, stored in the second buffer area, is read out in a color field sequential format, and during a period in which the other field is written in the second buffer area, the other field, stored in the first buffer area, is read out in a color field sequential format. A pixel interpolating circuit carries out an insertion-interpolating process on the field read out from the image storing unit, and outputs the resulting data. Thus, it becomes possible to prevent color breaking at the time of displaying motion images on a color field sequential type display by using a buffer area having a capacity of one frame.
