Abstract:
This invention provides an image processing apparatus which simplifies the circuit arrangement required for edge emphasis correction. For this purpose, the apparatus has a first color conversion unit (102) for color-separating input image data into lightness data and chromaticity data, a delay unit (103) for delaying the separated lightness data by N lines, and delaying the chromaticity data by N/2 lines, an image edge amount extraction unit (113) for extracting an image edge portion from the lightness data, a saturation amount extraction unit (114) for extracting the saturation component from the chromaticity data, and an image edge emphasis amount distribution unit (116) for distributing the emphasis amount of the edge portion to an edge emphasis unit (104) so that the distribution ratio for chromaticity correction is higher than that for lightness correction when the saturation component extracted by the saturation extraction unit (114) is large, and the distribution ratio for lightness correction is higher than that for chromaticity correction when the saturation component extracted by the saturation extraction unit (114) is small.

Abstract:
A control apparatus for a vehicle that is capable of enhancing fuel efficiency of an internal-combustion engine. The vehicle is provided with at least one electronically controllable vehicle-mounted accessory that can be driven by the engine, and energy storage means for storing energy generated by the at least one vehicle-mounted accessory being driven by the engine. The apparatus includes regenerative control means for performing regenerative control during deceleration of the vehicle according to a deceleration instruction from a driver, and drive-control means for performing drive-control of the at least one vehicle-mounted accessory during a vehicle running period other than a regenerative control period so that the energy storage means has a margin in energy storage capacity for storing energy to be generated by the at least one vehicle-mounted accessory being driven by the engine during the regenerative control.
Abstract:
An information processing apparatus includes a processing unit, a power supply control unit configured to control powering on and off of the processing unit, and a controller unit configured to access the processing unit irrespective of a power supply state of the processing unit. The power supply control unit powers off a processing unit that is not in use, powers on a processing unit that is accessed by the controller unit, and outputs a predetermined control signal to the controller unit. The controller unit recognizes that an error occurs in a case where, after accessing a processing unit, the controller unit does not receive a response from the accessed processing unit until a time-out time elapses, and delays recognizing the error when the control signal is received.

Abstract:
A support structure of the present invention includes a fixation member directly or indirectly heated, a supported object supported by the fixation member, and a sliding member provided on an outer periphery of the fixation member, the sliding member being slidable in a longitudinal direction of the fixation member. In the support structure, one fixation part of the supported object is fixed to the fixation member and another fixation part of the supported object is fixed to the sliding member. By this structure, it is possible to avoid concentration of stress and to surely support the supported object to the thermally expanding fixation member.
