20090256969 | METHOD AND APPARATUS FOR ADJUSTING QUALITY OF A DISPLAYED IMAGE - Specific image quality adjustment of an image is performed according to a setting made by a user, and contrast compensation is performed such that a brightness is kept unchanged at the center of a specific color region larger than a predetermined size, regardless of the setting of the image quality adjustment. The image quality adjustment is performed by selecting one of a plurality of filters with different frequency characteristics according to the setting of the image quality adjustment, and then performing filter processing on the image by using the selected filter. The contrast compensation is performed upon the image that has undergone the filter processing, by using a contrast compensation value related to the selected filter. | 10-15-2009 |

20090079372 | Electric Motor, Drive System Employing Multiple Electric Motors, and Method for Controlling the Same - The motor according to one aspect of the present invention has an output waveform correcting unit for correcting the waveform of the output signal of a magnetic sensor during operation of the electric motor. ID codes for identification purposes are assigned respectively to a plurality of magnetic sensors. The output waveform correcting unit receives, from an external device, output waveform correction values for the magnetic sensors together with the ID codes, and stores the output waveform correction values for the magnetic sensors in memory. The drive system according to another aspect of the present invention has a plurality of electric motors, and a system controller connected to the plurality of motors via a shared communication line. Each electric motor has an identification code register that stores an identification code for identifying each electric motor. The system controller has an individual control mode in which operation of individual motors is controlled by transmitting commands to individual electric motors together with identification codes via the shared communication line. | 03-26-2009 |
20090195202 | Electric Motor, Method for Correcting Sensor Output for the Same, and Control Circuit - The electric motor includes a coil array having a plurality of magnetic coils; a magnet array having a plurality of permanent magnets; a magnetic sensor outputting an output signal that changes in analog fashion depending on relative location of the magnet array and the coil array; a drive control circuit; and an output waveform correcting unit. The output waveform correcting unit corrects the waveform of the output signal of the magnetic sensor based on the voltage level of the output signal of the magnetic sensor, in such a way that the output signal of the magnetic sensor is shaped to prescribed waveform shape during operation of the electric motor. | 08-06-2009 |
