Image processing apparatus and control method therefor
An image processing apparatus which re-encodes encoded data, encoded with a pixel block having a predetermined number of pixels as a coding unit, while suppressing degradation of image quality, with a higher compressibility. For this purpose, when an encoded-image-data input unit inputs JPEG encoded data with an 8×8 pixel block as a coding unit, a redundancy estimation unit performs encoding on the encoded data, and sets an encoded data amount obtained by the coding, as a target code amount for a recompressor to perform coding in accordance with JPEG 2000 coding. The inputted encoded data is decompressed by a decompressor, and the recompressor generates encoded data in the previously-determined target code amount.

Method and system for increasing robustness of visual quality metrics using spatial shifting
A visual quality assessment method and system are based on deriving a quality metric by comparing sub-band approximations of a distorted image and an undistorted version of the same image, providing a good compromise between computational complexity and accuracy.

Due to inherent symmetries, the wavelet transform is “blind” to certain types of distortions. But the accuracy of the method is enhanced, and the blindness of the transform is overcome, by computing quality metrics for the distorted image as well as computing quality metrics for a shifted version of the distorted image and combining the results. |

Cross-component cryptographic message syntax message construction
Often, for reasons of wireless bandwidth conservation, incomplete messages are provided to wireless messaging devices. Employing cryptography, for confidentiality or authentication purposes, when including a received message that has been incompletely received can lead to lack of context on the receiver's end.

The source signature that provides the lowest error is, or is very close to, the true source signature and is then used in the separation process for the entire composite data set.

A controller of a switching power converter employs a dynamically adaptive power supply regulation approach that improves low-load and no-load regulation to achieve ultra-low standby power in a switching power converter. Under ultra-low load conditions when a deep-deep pulse width modulation (DDPWM) is applied, the controller decreases the actual on-time of the power switch of the switching power converter by decreasing the “on” duration of the control signal used to turn on or off the power switch, until the “on” duration of the control signal reaches a minimum value. To further reduce the on-time of the power switch, the controller reduces the power applied to the power switch to turn on the switch more slowly, while maintaining the “on” duration of the control signal at a minimum value. The minimum value of the “on” duration of the control signal and the minimum power applied to the switch are dynamically controlled. |

Differential signals are applied across a first pair of differential pads, and the signals are coupled wirelessly to a mating pair of conductive pads. Circuitry for generating and receiving differential signals is described. |

Electronic equipment with electric wiring
Electronic equipment includes a first water cutoff member and a second water cutoff member on the periphery of a hole communicating from outside with a space in which an electric component such as an electric circuit board is provided. This can prevent liquid, dust, and the like, which enter a first housing from outside, from entering the space. Thus, the electric component, etc. placed in the space can be prevented from being damaged due to an electric short-circuit. |

Electrically conductive path device
There is provided an electrically conductive path device which can prevent radiation noise. An electrically conductive path device includes three bus bars electrically connecting a motor unit to an inverter unit, capacitance portions creating stray capacitance and an insulator. In terms of the electrically conductive path device, switching operation of a semiconductor switch located inside an inverter of the inverter unit creates change in voltage which is transmitted to the bus bar corresponding to a path from the inverter to the motor. At that time, the change in voltage is not transmitted further to the motor but is transmitted to the bus bar corresponding to a path from the motor to the inverter via the capacitance portion formed between the facing portions, i.e. via the stray capacitance. |
