An information processing apparatus includes an acquisition unit configured to acquire restriction information about imaging functions from an imaging device connected to a network, a setting control unit configured to display a setting window in which after a parameter for one imaging function is selected, selectable parameters for other imaging functions are restricted in accordance with the selected parameter on the basis of the restriction information so that the imaging functions to be used are selected, and an information processing unit configured to acquire image information about an image captured using the selected imaging functions via the network.

A system, medium, and method compressing and/or restoring images. Such a data compression method may include selecting a mode from among a plurality of modes for compressing current data, according to predetermined criteria, and calculating a difference between the current data and reference data, according to the selected mode, and compressing the current data, or truncating a part of the current data and compressing the current data. Accordingly, it is possible to significantly lower the complexity of an image encoder/decoder system and exactly meet a picture-based CBR required by LCD DCC devices/systems.

Methods and devices for reconstructing coefficient levels from a bitstream of encoded video data for a coefficient group in a transform unit. Parity hiding is used to signal the parity of the upper left coefficient of the coefficient group. Based on the parity, either the significant coefficient flag or the greater-than-one flag is encoded/decoded for that coefficient, but not both. The greater-than-one flag is encoded/decoded irrespective of whether a maximum number of greater-than-one flags have been encoded/decoded with respect to the other coefficients in the coefficient group.

An image decoding method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes scaling, when a reference field has a different parity from a current field for motion compensation and when the decoded image signal is in a format in which the number of chroma pixels is vertically different from the number of luma pixels, a chroma motion vector of the chroma signal according to an accuracy for a luma motion vector of the luma signal so that a reference frame will coincide in phase of the chroma signal with a current frame. The method also includes performing motion compensation of the decoded image signal using the scaled chroma motion vector according to the accuracy of the luma motion vector of the luma signal.

An image processing method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes detecting a condition that a reference field has a different parity from a current field and that the number of chroma pixels is vertically different from the number of luma pixels. The method further includes shifting a phase of the chroma signal in the reference field in a vertical plus direction according a value of a motion vector in a vertical direction under the detected condition so that the reference field will coincide in phase of the chroma signal with a current field. The method also includes performing a motion compensation of the decoded image signal using the reference field.

An image decoding method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes scaling, when a reference field is a bottom field while a current field is a top field for motion estimation and when the decoded image signal is in a format in which the number of chroma pixels is vertically different from the number of luma pixels, a chroma motion vector of the chroma signal by mv/2¼, where mv is a vertical component in a luma motion vector of the luma signal. The method also includes performing motion compensation of the decoded image signal using the scaled chroma motion vector.

Provided is a digital image transmission system in a high definition multimedia interface (HDMI) format or a digital visual interface (DVI) format. A transmission and reception reinforcement device of the digital image transmission system includes a transmitter, a receiver, and a power supply circuit. The power supply circuit includes a first power supply unit supplying power to the transmitter and a second power supply unit supplying power to the receiver. Power output terminals of the first and second power supply units are connected to each other. External-power supply voltages respectively input to the first and second power supply units are output to the power output terminals. When all of the external-power supply voltages input to the first and second power supply units are lower than a predetermined voltage, an internal-power supply voltage present in a communication line between the host device and the display device is output to the power output terminals.
摘要:
A device is described that includes an encoder/decoder (CODEC) in which functionality is partitioned between a video front end (VFE) and a video back end (VBE). The VFE encapsulates functionality and image processing operations to support a variety of applications, and presents a flexible inter-processor by which an external master device can easily control these operations. The video back end (VBE) operates as an encoder and/or a decoder to generate encoded and/or decoded video sequences. The VFE and VBE may execute within an operating environment provided by a slave device.
