20120320106 | VIDEO IMAGE DISPLAY DEVICE - Provided is a video image display device that emits light so as to degrade image quality of illegally camcorded video images, thereby making it impossible to use the illegally camcorded image contents. A video image display system includes a projector that generates a display image based on digital video image signals; and a screen on which the image generated by the projector is projected and displayed. On a backside of the screen, there is provided an infrared ray emitting unit that emits infrared light from a video image display surface during a period while video images are being displayed on the screen. A light amount of the infrared light varies with time. It varies at a time interval equal to or less than a time constant of auto-iris control of a content recording device. | 12-20-2012 |
20120315018 | VIDEO IMAGE DISPLAY DEVICE, ANTI-CAMCORDING METHOD, AND VIDEO IMAGE DISPLAY SYSTEM - Light other than visible light is emitted from a video image display section such as a screen, together with display images, so as to degrade image quality of illegally camcorded video images, thereby making it impossible to use the illegally camcorded image contents. A video image display system includes a projector that generates a display image; and a screen on which the image generated by the projector is projected and displayed. On a backside of the screen, there is provided an infrared ray emitting unit that emits infrared light from a video image display surface during a period while video images are being displayed on the screen. The infrared ray emitting unit includes a wavelength cut filter that substantially does not transmit a predetermined wavelength component close to a visible light region, among the light emitted from the infrared light source | 12-13-2012 |
20120314085 | VIDEO IMAGE DISPLAY SCREEN, VIDEO IMAGE DISPLAY SYSTEM, AND METHOD FOR DETECTING CAMERA USED IN ILLEGAL CAMCORDING - Provided is a technique for easily detecting a person who attempts illegal camcording, by using device(s) that removes non-visible light as an anti-camcording interference image from a video image containing the non-visible light. A video image display system includes: a screen that displays a video image; an infrared ray emitting unit that projects infrared rays together with the video image toward an observer; and an infrared ray camera that detects infrared rays reflected by a video camera owned by the observer. The infrared ray camera particularly detects reflection light from an infrared ray cut filter attached to the video camera of the observer. | 12-13-2012 |
20120086862 | VIDEO DISPLAY DEVICE, VIDEO DISPLAY METHOD, VIDEO DISPLAY SCREEN AND LIQUID CRYSTAL DISPLAY DEVICE - A video display system of the present invention includes (i) a projector that generates a display image in accordance with a digital video signal and (ii) a screen on which an image generated by the projector is projected and displayed. Provided behind the screen is an infrared-emitting unit that emits infrared light through a video display surface during a period of time in which a picture is being displayed on the screen. This allows invisible light to be emitted through a video display section such as a screen together with a displayed image, thereby degrading the image quality of a re-shot picture and rendering use of re-shot image content impossible. | 04-12-2012 |
20100205204 | HOMOLOGY RETRIEVAL SYSTEM, HOMOLOGY RETRIEVAL APPARATUS, AND HOMOLOGY RETRIEVAL METHOD - A homology retrieval can be performed with higher accuracy than conventional technologies when comparing a query sequence with a target sequence, and retrieving a similar location in the target sequence. The sequence information of a query sequence and a genomic-scale target sequence is acquired, the acquired information is compressingly converted into a compressed query sequence and a compressed target sequence in each of which a homopolymer region including two or more consecutive identical bases is replaced with a single base of the bases, the two sequences are compared, and a refining search is performed for a compressed target partial sequence that matches the compressed query sequence in the compressed target sequence. For the refined compressed candidate sequence and the query sequence, based on the information on the number of consecutive identical bases in the each of the sequences before compression, the number of consecutive bases is compared between the two compressed sequences for each corresponding base, and the degree of similarity indicating homology of the candidate sequence with the query sequence is computed from a degree of match or a degree of mismatch in the number of consecutive bases. By ranking and selecting an arbitrary number of candidate sequences having relatively high homology with the query sequence from this degree of similarity, it is possible to avoid the influence of the number of consecutive identical bases in a homopolymer region, thereby performing a homology retrieval accurately. | 08-12-2010 |
20100003686 | PROCESS FOR PRODUCING TETRACYCLINE INDUCIBLE GENE EXPRESSING CELL LINE AND CONDITIONAL GENE KNOCKOUT CELL LINE, AND USES THEREOF - It is intended to provide a method of screening a so-called Tc inducible gene expressing cell line, in which the expression of a gene of interest is regulated depending on the presence/absence of a Tc compound regardless of the type of cell, easily with high efficiency. A gene-of-interest expression vector for transfecting a gene of interest into the genome of a host cell and a TA expression vector that expresses a transactivator that is switched to be bound or not to be bound to a tet operator sequence depending on the presence or absence of tetracycline are prepared. The gene-of-interest expression vector is a vector with a bicistronic regulatory sequence arranged downstream of the tet operator sequence and promoter sequence and between a gene-of-interest coding sequence and a selection marker coding sequence. These vectors are transfected into a host cell, and cell lines in which the selection marker of the gene-of-interest expression vector is expressed are selected. Thus, inducible gene expressing cell lines can be obtained in which the expression of a gene of interest can be controlled with Tc. | 01-07-2010 |
20090170714 | MULTIWELL INCUBATION APPARATUS AND METHOD OF ANALYSIS USING THE SAME - A continuous temperature-gradient incubation apparatus designed to solve the problem of moving of liquid vapor generated on the high-temperature side toward the low-temperature side to thereby cause condensation. | 07-02-2009 |
