摘要： The imaging device has an image sensor with a mosaic color filter array composed of three or four color elements. The color elements are arrayed such that each color element is opposite a pixel in said image sensor. The imaging device further has a first interpolate on processor, a color-transform processor, and a second interpolation processor. The first interpolation processor carries out a first interpolation process for generating a series of color signals in each pixel. The first interpolation processor interpolates missing color signals in each pixel on the basis of color signals generated in adjacent pixels. Then, the color-transform processor carries out a color-transform process for generating a series of color-transform signals from the series of color signals in each pixel. The second interpolation processor replaces at least one color-transform signal that is based on a color signal interpolated by the first interpolation process with at least one interpolated color-transform signal. The second interpolation processor carries out a second interpolation process for generating the interpolation color-transform signal from color-transform signals of surrounding pixels.

摘要： An image interpolating device comprises a color filter, in which R, G, and B color filter elements are disposed in a checkerboard arrangement, and an imaging device which generates R, G, and B-signals corresponding to the color filter elements. In an interpolation process, the differences between a G-signal of an objective pixel and G-signals of pixels adjacent to the right, left, upper, and lower sides of the objective pixel are checked. For example, if the G-signal of the left side pixel is the closest to that of the objective pixel, a luminance value Y, a color difference signal Cb, and a modified luminance signal YG of the objective pixel are obtained using the R, G, and B-signals of the left side pixel. A B-signal of the objective pixel is obtained using the modified luminance value YG, and the color difference signal Cb.

摘要： An image compression apparatus transforms original image data partitioned into first blocks, each of which is composed of a plurality of pixels, to reduced-image data composed of a smaller number of pixels than that of the original image data. Further, the apparatus generates expanded-image data from the reduced-image data by fluency transform. Based on the expanded-image data and the original image data, differential value data is obtained, and the differential value is transformed to differential DCT coefficient data by DCT processing. Based on the differential DCT coefficient data, a code-length corresponding to a bit-length necessary for a Huffman coding is calculated. The fluency transform has a plurality of modes, each mode being selected in order, the code-length being calculated for all of the modes. Then, a mode which makes the code-length minimum is determined as the optimum mode. The differential DCT coefficient data is Huffman encoded, so that Huffman-encoded bit data is generated. Then, in an image expansion apparatus, the original image data is restored on using the optimum mode, reduced-image data and the Huffman-encoded bit data.

摘要： An image compression device to compress a still image comprises a DCT processing circuit, a quantization processing circuit, a bit separation processing circuit, a grouping circuit, and an encoding processing circuit. In the bit separation processing circuit, quantized DCT coefficients are subjected to a bit separation processing, such that higher-rank quantized DCT coefficients and lower-rank quantized DCT coefficients are obtained. Thus, a total bit number (length) of compressed image data is decreased. An image expansion device to expand the compressed image data comprises a decoding processing circuit, an inverse grouping circuit, a bit synthesis processing circuit, a dequantization processing circuit, and an IDCT processing circuit. In the bit synthesis processing circuit, the higher-rank quantized DCT coefficients and the lower-rank quantized DCT coefficients are subjected to a bit synthesis processing, such that the quantized DCT coefficients are obtained. Thus, the original still image data is reproduced.

摘要： An image signal compressing device having a spatial frequency data amount setting unit and a quantization table generation unit. A set data amount is set in the spatial frequency data amount setting unit for each of a plurality of spatial frequencies based on a preset total data amount and a discrete cosine transformation (DCT) data statistical amount corresponding to quantized DCT coefficients using a quantization table in which all quantization coefficients are "1". An amount of encoded data obtained using a predetermined quantization coefficient is estimated in the quantization table generation unit. The predetermined quantization coefficient is adopted as a resultant quantization coefficient of the quantization table when the estimated data is not greater than the set data amount set in the spatial frequency data amount setting unit.

摘要： An image compression and expansion apparatus obtains an average value of a single block (8×8 pixels) in a first matrix (64×64 pixels) of the original image data, to generate reduced image data of a second matrix (8×8 pixels). A sub-matrix, which is displaced from the second matrix by a predetermined amount, is obtained in such a manner that a pixel of the second matrix is contained in the sub-matrix. 8×8 pixels of the sub-matrix are subjected to a two dimensional discrete cosine transformation, to obtain reduced DCT coefficient data. The reduced DCT coefficient data is subjected to an expanded inverse discrete cosine transformation to obtain expanded image data of a matrix (m×n pixels). The displacement direction and the displacement amount of the sub-matrix relative to the second matrix, and the values of “m” and “an” are selected in such a manner that the expanded image data becomes as close to the original image data as possible.

摘要： A compression apparatus transforms original image data partitioned into first blocks, each of which is composed of a plurality of pixels, to reduced-image data composed of a smaller number of pixels than that of the original image data. The reduced-image data is subjected to a fluency transform to generate expanded-image data partitioned into second blocks corresponding to the first blocks. The fluency transform has a plurality of modes, and one mode is selected from the plurality of modes, thus the expanded-image data is generated in accordance with the selected one mode. An error, which represents a difference between the original image data and the expanded-image data, is calculated in each of the plurality of modes. Then, an optimum mode, by which the error becomes a minimum value, is determined among the plurality of modes. On the other hand, an expansion apparatus generates the expanded-image data by applying the fluency transform using the optimum mode.
