摘要： A wavelet transform unit performs a wavelet transform on original images and a quantization unit quantizes wavelet transform coefficients. A ROI selector selects a region of interest or regions of interest in the original image, and a ROI mask generator generates ROI masks with which the wavelet transform coefficients (which are also called ROI transform coefficients) corresponding to the regions of interest are specified. By referring to the ROI masks, a lower-bit zero substitution unit substitutes low-order bits of non-ROI transform coefficients with zeros. An entropy coding unit entropy-codes the wavelet transform coefficients sequentially from high-order bit-planes, after the substitution. A coded data generator turns coded data into streams together with parameters and then outputs coded images.

摘要： A twin head for use in an electronic still camera includes a shield plate, first and second head chips bonded on opposite sides of the shield plate, and first and second reinforcing core members further bonded on first and second head chips, respectively. Each of the first and second head chip members has an elongated face that faces a recording medium and a magnetic gap defined at an intermediate portion of the elongated face. The length Wh of the elongated face is between 0.3 millimeter and 1 millimeter. Each of the first and second reinforcing core members has a coil wound thereon. The first and second head chip members, the shield plate, and the first and second reinforcing core members are bonded together such that the elongated faces of the first and second head chip members are in flush with each other and that the magnetic gaps of the first and second head chip members are aligned to each other.

摘要： In an image coding apparatus, a ROI setting unit sets a ROI region in an image. An entropy coding unit entropy-codes the image. A ROI information coding unit encodes information for specifying the ROI region. A codestream generator generates a codestream in a manner that the coded image and the coded information are explicitly included in the codestream. When a plurality of ROI regions are set in the image, the information may include a degree of priority.
