| 20090219276 | DRIVING DEVICE AND DRIVING METHOD FOR IMAGE DISPLAY DEVICE - A display driving device and method capable of canceling an offset voltage while suppressing a delay in outputting an image signal to the display device by the time required for the image signal to be completely received in the display device. In an exemplary embodiment, when an image signal is input to an operational amplifier, a pixel of the display device, to which a voltage based on the image signal is applied, and an output terminal of the operational amplifier are connected to each other. The image signal is input to the operational amplifier, and, when charges corresponding to an offset voltage generated in the operational amplifier have accumulated in a capacitor, the image signal is input to the operational amplifier together with the charges accumulated in the capacitor while the connection between the pixel and the output terminal of the operational amplifier is maintained. | 09-03-2009 |

The switch circuit includes an n-channel type field effect transistor. The control unit applies the first control voltage to the n-channel type field effect transistor, so that the n-channel type field effect transistor transits from a non-conductive state to a conductive state. | 06-30-2011 |
| 20120001952 | DRIVING CIRCUIT AND DISPLAY APPARATUS - A driving circuit includes a pair of operational amplifiers, one producing an analog voltage output of positive polarity, the other producing an analog voltage output of negative polarity. An output switching circuit interchanges these outputs between a pair of data lines. One or both of the operational amplifiers includes a parasitic diode having one terminal connected to the output terminal of the operational amplifier and another terminal normally connected to a power supply voltage of the operational amplifier. When the output of the operational amplifier is switched, a protective switching circuit temporarily disconnects the parasitic diode from the power supply of the operational amplifier and instead connects it to a power supply line carrying a voltage high enough, or low enough, to ensure that the parasitic diode is not forward biased by the existing voltage on the data line to which the output is switched. | 01-05-2012 |

| 20080304104 | Image processing apparatus and method for processing an image - An image processing apparatus performs authentication of users. A first and second user inputs first and second user information, respectively, through an input section. A controller controls the authentication section to perform first authentication of the first user information, and controls the job execution section to execute the first job if the first authentication is successful. The controller controls the job execution section to halt execution of the first job upon an interrupt by the second user, and to execute the second job when the first job remains interrupted. A memory stores interrupt information indicative of a status of execution of the first job when the interrupt occurs. The controller controls the authentication section to perform second authentication of the first user information after the second job has been completed, and then controls the job execution section to resume execution of the first job if the second authentication is successful. | 12-11-2008 |
| 20100245899 | Image forming apparatus - A job managing section stores print jobs as jobs-in-queue when they are received through a receiving section. Each job contains original user information. Each job is a currently executed job when it is being executed by an executing section. An error detecting section obtains error information from the executing section upon an error in the currently executed job. An updating section stores the currently executed job as a job-on-hold into the job managing section if a determining section determines that the currently executed job should be placed on hold. A log-in authenticating section performs authentication of an operator user based on the operator user information inputted by the operator user. Upon successful authentication, a user name comparing section determines whether the operator user information and the original user information contained in the job-on-hold coincide. If they coincide, a displaying section indicates to the operator user that a job-on-hold exists. | 09-30-2010 |
| 20120062915 | PRINTING DEVICE AND PRINT JOB CONTROL METHOD - A printing device includes a receiving part receiving print job data, an analysis part, a memory part, an image forming part that executes a print process of image information using first and second consumable products and that includes a remaining amount detecting part, and a print control unit that controls the print process. When the remaining amount of the first consumable product is detected to be lower than a predetermined amount, the print process using the first consumable product is temporarily suspended, the memory part stores the image information and the print information of the print job data that are sequentially received by the receiving part. When the print information for another print process not using the first consumable product is stored in the memory part, the print control unit deletes information relating to the print job data of the suspended print process. | 03-15-2012 |
