摘要： A coding apparatus includes a predicting unit, an intermediate-code generating unit, a first coding unit and a second coding unit. The predicting unit generates a piece of prediction data based on each piece of pixel data constituting a color image. The intermediate-code generating unit compares each piece of prediction data with the corresponding piece of pixel data, to generate an intermediate code in accordance with whether or not a difference between each piece of prediction data and the corresponding piece of pixel data is in a predetermined range. The first coding unit performs entropy coding on the generated intermediate code. The second coding unit performs entropy coding on the generated intermediate code. The intermediate-code generating unit assigns each generated intermediate code to either of the first and second coding units according to whether or not the difference is in the predetermined range.

摘要： The present invention is directed to an image information encoding apparatus adapted for performing intra-image encoding on the basis of resolution of color components and color space of an input image signal. In the image information encoding apparatus (10), an intra prediction unit (23) serves to adaptively change block size in generating a prediction image on the basis of a chroma format signal indicating whether resolution of color components is that of any one of 4:2:0 format, 4:2:2 format and 4:4:4 format, etc., and a color space signal indicating whether color space is any one of YCbCr, RGB and XYZ, etc. In addition, an orthogonal transform unit (14) and a quantization unit (15) serve to also change orthogonal transform technique and quantization technique in accordance with the chroma format signal and the color space signal. A reversible encoding unit (16) encodes the chroma format signal and the color space signal to include the encoded signals thus obtained into image compressed information.

摘要： PROBLEM TO BE SOLVED: To provide an image control apparatus for encoding image data to reduce a data transfer amount of a memory while suppressing deterioration of image quality.
SOLUTION: A format conversion part 10 divides each pixel component of image data 2 of a first format expressing gradation of each pixel component with a plurality of bits into a prescribed bit group, and couples the bit group on the basis of bit depth to be converted into the image data of a second format. An image encoding part 20 encodes the image data converted into a format with a plurality of encoding methods, and selects the encoding method in response to image quality indexes of encoding data to output corresponding encoding data. A memory input control part 30 assigns a memory region storing a plurality of the pixel components composing the image data of the second format in response to a selected encoding method to be collectively stored in each of the plurality of the pixel components. Thus, the memory transfer amount is reduced when being decoded while suppressing deterioration of image quality.

摘要： PROBLEM TO BE SOLVED: To efficiently code moving pictures of which the luminance changes with respect to time, such as, fading and dissolving images.
SOLUTION: A variable length decoder 303 decodes coding data 300. The data include a predictive error signal, indicating an error of a predictive image signal to a moving picture signal, including a luminance signal and two color difference signals; motion vector information 414; and index information 415, indicating a combination of at least one reference image number and a predictive parameter prepared for each of the luminance and two color-difference signals, beforehand. A frame memory/predictive image generator 308 generates a predictive image signal 412, according to a combination of the reference image number and the predictive parameter indicated by the decoded index information, and uses the predictive error signal and the predictive image signal, to generate a reproduced moving picture signal.
