Image processing device and image processing method
The present technology relates to an image processing device and an image processing method which allow a deblocking filtering process to apply filtering appropriately. A pixel (p0i) of which the value is 255 (solid line) before a deblocking process changes greatly to 159 (dot line) after a conventional deblocking process. Therefore, a clipping process having a clipping value of 10 is performed in strong filtering, whereby the pixel (p0i) of which the value is 255 (solid line) before the deblocking process becomes 245 (bold line). Thus, a change in the pixel value occurring in the conventional technique can be suppressed as much as possible. This disclosure can be applied to an image processing device, for example. |

Output control method for a digital controller of a source measure unit
An output control method for a controller includes the following steps. At each of detection time points, the controller detects a detection voltage value and a detection current value of a load. In a voltage control mode, the controller generates a setting parameter to control the power amplifier according to part of the detection voltage values. In a current control mode, the controller generates the setting parameter to control the power amplifier according to part of the detection current values. When the controller switches to the voltage control mode or the current control mode, the controller determines a ratio between the detection current value and the detection voltage value at one of the detection time points and the setting parameter is generated according to the ratio. Therefore, the bandwidth is substantially the same no matter if the controller operates in the voltage control mode or the current control mode. |

Sleeve monopole antenna with spatially variable dielectric loading
A dielectric loaded sleeve monopole antenna has a dielectric loading within the sleeve enables stable impedance in a dynamic operating environment. The use of a dielectric filling in the sleeve portion of the antenna enables tight control of the input impedance over frequency establishing stable broadband operation in challenging operating environments.

As a result, the sleeve essentially acts as an impedance transformer enhancing control over the input impedance to the antenna. The spatial variability in the dielectric filling may be realized as arrangements of single or multiple dielectric materials machined to synthesize the desired effective dielectric properties. |
