摘要： This invention relates to an image encoding method and apparatus, and particularly has as its object to satisfactorily control the amount of encoded image data. In order to achieve this object, according to this invention, there is disclosed a technique for sequentially controlling the code amounts in accordance with accumulated code amount information and accumulated encoded area information, so that variable-length codes of an image fall within a predetermined memory capacity in a single pass. More specifically, in an image processing apparatus having a compression processor (15) for compressing input image information, and a memory (16) for storing encoded data by the compression processor (15), a code amount controller (14) calculates a reference code amount on the basis of the input image information, and controls the encoding condition of the compression processor (15) on the basis of the calculated reference code amount.

摘要： A data transmission system discriminates, for each one of a plurality of pieces of data representing an image provided in a frame, whether the one piece of data is a first type of data, which is to be developed into bit map data in a bit map area corresponding to the frame, or a second type of data, which is not to be developed into bit map data. The first type of data is developed into bit map data in the bit map area in response to the discrimination. Layout information of the second type of data in the frame is generated such that variation or rotation of the developed bit map data can be directed in the layout information. The developed bit map data, the generated layout information, and the second type of data are transmitted separately to an external apparatus.

摘要： To perform processing to increase the number of pixels of inputted image data, the inputted image data having low resolution is converted to image data having high resolution. For this conversion, one pixel of the low resolution data is interpolated, a difference value between a predetermined value and image data included in an interpolating-pixel block which corresponds to a pixel of interest of the low resolution data, is calculated, and pixel values of pixels in the interpolation-pixel block are determined in accordance with the difference value. Furthermore, multi-level image data on which pixel values have been determined is binarized by the dither method, to determine pixel values such that the smaller the absolute value of the difference value is, the larger the difference from the predetermined value.

摘要： With this invention, upon scanning a print, since additional information recorded together with that print is reproduced while displaying the scanned image, a special effect that cannot normally be obtained from still images can be obtained.A print on which image information and additional information, different from the image information, are printed is scanned by a scanner (209). An additional information demultiplexer (210) demultiplexes that additional information, which is decoded by an error correction decoder (211). After that, the image and the decoded additional information (moving image or/and acoustic information) are simultaneously reproduced in combination.

摘要： This invention is an image processing apparatus capable of adding a reference frame for accurately specifying an image region printed on a printing medium. An image forming unit (13) converts an input image for printing into that of a predetermined resolution. An additional information multiplexer (14) embeds additional information in each predetermined region of the resolution-converted image. A reference frame addition unit 15 adds a predetermined reference frame to the perimeter of the image in which the additional information is embedded. A printer (16) prints the image having the additional information embedded in it and the reference frame onto a printing medium, and outputs a printed image (17).

摘要： Upon embedding additional information in image information, since an image region in which the additional information can be embedded is limited, the information size that can be embedded is often limited, and all pieces of additional information cannot be embedded. Before the additional information is embedded in the image information, distribution information of pixel values is obtained by scanning the image information, and the information size that can be embedded is detected and displayed on the basis of the obtained distribution information of pixel values.

摘要： This invention provides an image processing apparatus which can effectively remove conspicuous noise contained in image data, while suppressing deterioration of image information. Image data containing noise is input from an input terminal (100). Based on the output condition upon outputting image data after noise is removed, a parameter determination module (103) determines predetermined parameters used in a noise removal process. An example of the output condition is information associated with a resolution upon outputting image data. An individual noise removal module (104) removes noise contained in the image data using the parameters, and image data after the noise has been removed is output from an output terminal (105).
