20130208144 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, IMAGE PROCESSING PROGRAM - A flash detection unit calculates a line average luminance of each line of the current screen of image data and a screen average luminance of a past screen at least one screen before the current screen and compares the calculated line average luminance with the calculated screen average luminance to detect whether the current screen includes a line of high luminance due to a flash. A holding unit holds the past screen of the image data. A flash correction unit, if it is detected that some lines of the current screen have high luminance, replaces the lines having high luminance in the current screen with corresponding lines of the past screen held in the holding unit to correct the image data. | 08-15-2013 |
20130208356 | AUTOSTEREOSCOPIC DISPLAY APPARATUS - An autostereoscopic display apparatus includes a display in which color pixels of different colors are periodically arranged in a horizontal direction and color pixels of an identical color are arranged in a vertical direction, and a plurality of cylindrical lenses placed on the display and arranged parallel to each other, through which the color pixels are magnified and observed. When a pixel pitch of the color pixels in the horizontal direction is defined as px, a lens pitch of the cylindrical lenses is defined as L, an inclined angle of boundaries of the cylindrical lenses with respect to the vertical direction is defined as θ, and m is a positive integer, px, L and θ fulfill the formula (1). | 08-15-2013 |
20130208357 | AUTOSTEREOSCOPIC DISPLAY APPARATUS - An autostereoscopic display apparatus includes a two-dimensional display including color subpixels that are arranged in a horizontal direction and in a vertical direction, and a plurality of cylindrical lenses through which the color subpixels are observed. px is a horizontal pixel pitch of the color subpixels, py is a vertical pixel pitch of the color subpixels, Lx is a horizontal lens pitch of the cylindrical lenses, and θ is an inclined angle of boundaries to the vertical direction. Ax and Ay are relatively prime natural numbers, Ax is equal to or larger than two, and Bx is a minimum natural number by which a value GF indicated in the formula (2) represents an integer value. Px, py, Lx and θ satisfy the relational expressions represented by the formula (1) to the formula (3). | 08-15-2013 |
20130215326 | LIQUID CRYSTAL DISPLAY APPARATUS, AND DRIVING DEVICE AND DRIVING METHOD OF LIQUID CRYSTAL DISPLAY ELEMENT - A look-up table unit converts input video signal data of N bits into (M+F+D) bit data by performing inverse gamma correction and linear interpolation. An error diffusion unit converts the (M+F+D) bit data into (M+F) bit data by error diffusion processing. A frame rate control unit converts the (M+F) bit data into M bit data by frame rate control. A sub-frame data conversion unit, by using a gradation driving table and the M bit data, generates sub-frame data in which all sub-frames include a step-bit pulse respectively, and in which the number of sub-frames to be in a drive state every time the drive gradation increases by one, is increased one by one. | 08-22-2013 |
20130215335 | PROJECTION-TYPE IMAGE DISPLAY APPARATUS - A dynamic iris controller includes: a diaphragm and video-image controller including a video-image analyzer analyzing a picture signal, an association setting unit setting a diaphragm stop of a diaphragm mechanism, a color balance correction value, and a lightness correction value according to analysis data analyzed in the video-image analyzer, and a black period controller setting a black period in the picture signal according to a predetermined black time length; a diaphragm driver outputting a drive signal to the diaphragm mechanism so as to set the diaphragm stop of the diaphragm mechanism to be fully closed for the black period set by the black period controller and to set the diaphragm stop to have a value set by the association setting unit for the other period; and a video-image processor correcting color balance and lightness of the picture signal using the correction data set in the association setting unit. | 08-22-2013 |
20130218559 | NOISE REDUCTION APPARATUS, AUDIO INPUT APPARATUS, WIRELESS COMMUNICATION APPARATUS, AND NOISE REDUCTION METHOD - A speech segment of a voice sound is detected based on a first sound pick-up signal obtained based on the voice sound. A voice incoming direction of the voice sound is determined using the first sound pick-up signal and a second sound pick-up signal obtained based on a picked-up sound. A noise reduction process is performed to reduce a noise component carried by the first sound pick-up signal by using the second sound pick-up signal, wherein a noise reduction amount adjusted in accordance with the voice incoming direction is used in the noise reduction process. | 08-22-2013 |
20130218575 | AUDIO INPUT APPARATUS, COMMUNICATION APPARATUS AND CONDITION NOTIFICATION METHOD - The used condition of a simplex communication apparatus is notified with a light-emitting device attached to the communication apparatus. It is determined whether a communication mode of the simplex communication apparatus is a transmission mode or a standby mode. A sound pick-up state of a sound carried by a speech signal to be transmitted is determined if the communication mode is the transmission mode. The light-emitting device is controlled so that it is turned off, turned on or repeatedly turned on and off based on determination results of the communication-mode determination and the sound pick-up state determination. | 08-22-2013 |
20130223656 | WATERPROOF STRUCTURE AND ELECTRONIC EQUIPMENT INCLUDING THE SAME - A waterproof structure includes a housing, an electroacoustic transducer, a packing and an annular member. The electroacoustic transducer has a case formed with tone holes. The packing is interposed between the housing and the electroacoustic transducer and has a thin film part on a part opposed to the tone holes. The annular member is interposed between the thin film part and the case and surrounds the tone holes. A space surrounded by the thin film part, the annular member and the case is formed. The annular member is configured to bias the thin film part of the packing. | 08-29-2013 |
20130295306 | POLYESTER RESIN COMPOSITION AND A PRODUCTION METHOD THEREFOR - Disclosed are a copolymeric polyester resin composition having outstanding colour stability (transparency) and a production method therefor. The copolymeric polyester resin composition comprises: between 95 and 99.99 percent by weight of a copolymeric polyester resin having a structure which is obtained by the copolymerisation of a dicarboxylic acid component and a diol component that comprises isosorbide, and in which there is repetition of a dicarboxylic acid moiety derived from the dicarboxylic acid component and a diol moiety derived from the diol component; and between 0.01 and 5 percent by weight of an antioxidant selected from the group consisting of hindered phenol-based antioxidants, phosphite-based antioxidants, thioether-based antioxidants and mixtures thereof. | 11-07-2013 |
