    摘要: An ROI setting apparatus including an ROI recognition unit and an ROI control unit is provided. In one embodiment, the ROI recognition unit contains multiple ROI recognition modules for recognizing an ROI of image data according to various methods to obtain a recognition result. The ROI control unit selects one ROI recognition module out of the ROI recognition modules and sets ROI information based on the recognition result. The ROI recognition module may be selected according to an instruction from a user input via an operation unit, or a scene type selected by a scene selection switch of an image capture unit. The ROI control unit may perform operations such as selecting, enlarging, or reducing the ROI recognized by the ROI recognition module, or changing the ROI recognition conditions according to the respective instructions from the user input via the operation unit.

    摘要: A code processing apparatus for generating a file including a JPEG 2000 codestream or a JPEG 2000 family format including the JPEG 2000 codestream is disclosed that includes a packet arranging part for arranging the order of a plurality of packets included in the JPEG 2000 codestream according to an extended progression order selected from a group of extended progression orders including “xTxxx”, “xxTxx”, “xxxTx”, and “xxxxT”. Each “x” in the extended progression orders represents one of a resolution level characteristic, a layer characteristic, a component characteristic, and a precinct characteristic. The leftmost “x” of each extended progression order corresponds to an outermost characteristic of the extended progression order. “T” represents a tile characteristic.

    摘要: An image decoding device for decoding a hierarchically encoded compressed code obtained by dividing an image into a plurality of tiles and performing discrete wavelet transform on the pixel values of the image tile by tile includes a tile boundary smoothing part that performs smoothing of tile boundary distortion on the image after the decoding by application of a low-pass filter. The tile boundary smoothing part controls the degree of smoothing of the low-pass filter according to the ratio of the decoding quantity to the entire quantity of the compressed code. The decoding quantity is the portion of the compressed code which portion is to be decoded.
