Publication number: 20140085174Abstract: A liquid crystal display includes a liquid crystal panel and a first to nth control substrates (n is an integer which is 2 or greater) which control the liquid crystal panel. When the first control substrate enters an operable status, the first control substrate transmits a readiness signal to the second control substrate which is at a next stage, and when the nth control substrate determines that the nth control substrate receives a readiness signal from a control substrate at a previous stage and is in an operable status, the nth control substrate transmits a readiness signal to the first control substrate, thereby being able to suppress a synchronization failure between the plurality of control substrates which are provided in a liquid crystal display.Type: ApplicationFiled: May 17, 2012Publication date: March 27, 2014Applicant: Sharp Kabushiki KaishaInventor: Akihiko Inoue

Patent number: 8503721Abstract: An image judgment device stores element characteristic information for each element of a characteristic part of a sample object and first and second positional information defining a position of each element, selects the first or the second positional information, and acquires image characteristic information for a partial image in an image frame considered as an element specified by the first positional information based on a first axis. The image judgment device also extracts image characteristic information for a partial image in an image frame considered as an element specified by the second positional information based on a second axis (which is acquired by rotating the first axis), specifies element characteristic information for an element corresponding to a position of the partial image, and judges whether the characteristic part appears in the image frame with use of the specified element characteristic information and the extracted image characteristic information.Type: GrantFiled: December 12, 2008Date of Patent: August 6, 2013Assignee: Panasonic CorporationInventors: Hiroto Tomita, Akihiko Inoue

Publication number: 20110273489Abstract: A gradation change detection circuit determines whether a gradation value has been changed from a previous frame. In at least one example embodiment, a first frame memory stores, when the gradation value is changed, a gradation value before change. A hold count calculation circuit determines a hold count indicating the number of frames inputted after the change of the gradation value. A second frame memory stores the determined hold counts. An emphasis conversion circuit performs a process of emphasizing a change in gradation value on a video signal, and makes a degree of emphasis smaller with a larger hold count. A liquid crystal panel is driven based on a video signal obtained by an overdrive circuit. By this, double optical responsivity occurring due to overdrive drive is prevented.Type: ApplicationFiled: January 7, 2010Publication date: November 10, 2011Applicant: Sharp Kabushiki KaishaInventor: Akihiko Inoue

Patent number: 7953283Abstract: A portable terminal including an input unit (1001), through which images are entered, an encoding unit (1002) operable to encode the input images, thereby providing encoded data, a transmitting unit (1003) operable to transmit the encoded data to a communication counterpart, a receiving unit (1006) operable to receive communication counterpart-related information from the communication counterpart, and a mode-determining unit operable to determine an encoding method. The mode-determining unit receives the information on each of the self-terminal and the communication counterpart, thereby providing the determined encoding method. As a result, even when each of the self-terminal and the communication counterpart retains a sufficient level of remaining battery power, the encoding method is properly changed to suppress unwanted power consumption, whereby communication between the self-terminal and the communication counterpart can be made for a longer period of time.Type: GrantFiled: January 16, 2006Date of Patent: May 31, 2011Assignee: Panasonic CorporationInventor: Akihiko Inoue

Patent number: 7929000Abstract: In one embodiment of the present invention, a frame interpolation process circuit performs an interpolation process on a video signal in units of frames. A time-division gradation process circuit performs gradation level conversion for distributing brightness for one frame cycle to two sub-frame cycles, i.e., first and second sub-frame cycles. A gradation level change detection circuit detects whether a gradation level of each pixel has changed between consecutive sub-frames. For any pixel having its gradation level changed, an overshoot process circuit outputs, instead of an output signal of the time-division gradation process circuit, a video signal obtained by subjecting an output signal of the frame interpolation process circuit to gradation level conversion for emphasizing a temporal change of the signal. A predetermined-times higher speed process circuit may be added to this circuit configuration, or may be substituted for the frame interpolation process circuit.Type: GrantFiled: November 30, 2007Date of Patent: April 19, 2011Assignee: Sharp Kabushiki KaishaInventor: Akihiko Inoue

Patent number: 7903129Abstract: A simple double-speed process circuit 60 outputs a video signal V1 twice at a double speed in units of frames. A time-division gradation process circuit 50 performs gradation level conversion on the video signal in order to distribute brightness for one frame cycle to two sub-frame cycles, i.e. first and second sub-frame cycles. An overshoot process circuit 40 performs gradation level conversion on the video signal in order to-emphasize a temporal change of the signal. A drive circuit 20 drives liquid crystal display elements 31 using a video signal V2 obtained through processing by the three circuits. A frame interpolation process circuit may be added to this circuit configuration or may be substituted for the simple double-speed process circuit 60. This makes it possible to improve moving image display performance, while making up for a lack of response speed of the display elements.Type: GrantFiled: June 15, 2007Date of Patent: March 8, 2011Assignee: Sharp Kabushiki KaishaInventor: Akihiko Inoue
