20130222359 | DISPLAY DEVICE, DISPLAY METHOD FOR SAME, AND LIQUID CRYSTAL DISPLAY DEVICE - When an idle period is started, a voltage of the control signal is changed from a value H to a value L. As a result, the analog amplifiers provided in the signal line driver circuit are switched from the normal state to the low-driving power state. At this time, the data signal lines are set to have a constant potential. A gate voltage is changed from Vgh to Vgl at the same time as when the control signal was changed from the value H to the value L. As a result, the gate of each TFT returns to the OFF state from the ON state. The control signal remains at the value L until the idle period is over. In other words, when the next driving period is started, the voltage of the control signal is changed from the value L to the value H. As a result, the analog amplifiers in the signal line driver circuit are switched back to the normal state from the low-driving power state. | 08-29-2013 |

20110150350 | ENCODER AND IMAGE CONVERSION APPARATUS - It is an object to provide a method of calculating a coding cost by which the magnitude relation of the amounts of generated codes can be estimated with high accuracy. A cost calculation part generates a differential block between a coding object block and a prediction block. Hadamard Transform is performed on the differential block to generate a frequency component block. A conversion factor matrix is generated with the information of a quantization matrix reflected thereon.

20110158325 | IMAGE CODING APPARATUS AND IMAGE CONVERSION APPARATUS - A statistical value calculation part specifies macroblocks positioned around an object macroblock and calculates a minimum average value of activities of the macroblocks. When images of the macroblocks are flat and the minimum average value is smaller than an activity of the object macroblock, the minimum average value is set as an adjustment value. A correction factor determination part determines a correction factor on the basis of the adjustment value and a factor determination table. By multiplying a reference quantization step value by the correction factor, a quantization step value of the object macroblock is determined. Since the quantization step value reflects a distribution of the activities of the macroblocks, it is possible to suppress a local change of the quantization step value. | 06-30-2011 |
20110200102 | IMAGE CODING APPARATUS AND IMAGE CONVERSION APPARATUS - An image coding apparatus obtains a quantization parameter of a macroblock to be encoded.

After the encoding, a quantization parameter correction part calculates the cumulative target amount of codes by accumulating the target amounts of codes set for the encoded macroblocks, respectively, and calculates the cumulative amount of generated codes by accumulating the respective amounts of generated codes of the encoded macroblocks. If the cumulative amount of generated codes is larger than the cumulative target amount of codes, the quantization parameter correction part increments the correction value. A new macroblock to be encoded is quantized more coarsely than the encoded macroblocks. | 08-18-2011 |
