摘要:
An apparatus for recording video data by forming many tracks on a recording medium and/or for reproducing the video data from the tracks is provided with a memory which is arranged to have recording video data or reproduced video data supplied thereto. The apparatus detects the picture change-over portion of the video data obtained within the tracks and controls, in accordance with the detected position, an offset degree between the writing and reading addresses of the memory.

The disclosure presents an image encoding device which changes a position of a partial area in which there are pixels encoded by using only pixels in the present picture at intervals, or an image encoding device which decides the partial area such that the partial area is a continuous area in a picture. Accordingly, the device efficiently prevents to spread errors, can avoid frequent deteriorations of images, and can improve a quality of encoded images.

An image information transmission method divides a frame of image data into a plurality of blocks each having a unit block constituted by a predetermined number of picture element (pixel) data. A plurality of distinguishable distribution data representing the distribution of levels of this pixel data are formed for each block from the pixel data. Position data representing the levels of the pixel data in terms of position in the distribution are also formed. A unit data block is formed for each block from the distribution and position data. The unit data blocks corresponding to successive blocks are serially transmitted in predetermined order, and the sequence of transmission of distribution data in each unit data block is changed in accordance with predetermined information. This predetermined information is stored in accordance with the transmission sequence of the distribution data and the pixel data of the unit picture element block thus transmitted are restored using the distribution data and the plurality of position data in the transmitted unit data block.

In a decoding method of decoding encoded image data which has been hierarchically encoded in advance, a size of an image to be outputted is determined, and then the encoded image data is decoded up to a layer of hierarchy which is at least one layer more than a minimum number of layer/layers of hierarchy necessary to acquire an image of the determined size.

The subject matter of the invention is to add information to image data of multicolor image and monochromatic image. An image processing apparatus capable of adding information on raw data performs a dispersion conversion on the spectrum of the additional information by multiplying a code sequence of the PN sequence generator 114 by the additional data which is inputted from the input terminal 111 and converted into serial data in P/S converter 112. At this time, the data sequence transmitted from the image signal processor 102 to the printer engine 107 is converted by the scan converter 109 to correspond to the spatial axis for desperation. The converted data sequence is added to the output from the adder 113 by the adder 110, and reconverted to the original scan by the scan inverter 115.

An apparatus for reproducing signals from a multiplicity of parallel tracks in a recording medium by means of n number of rotary heads, n being an integer not less than 3. A transportation device for transporting the recording medium is controlled on the basis of two kinds of signal: namely, a tracking control signal for leading one of the n number of rotary heads to one of m number of tracks contained in consecutive n number of tracks, m being an integer not less than 2; and a track shift signal which is generated in accordance with the result of a determination as to whether the n number of rotary heads are tracing expected tracks and which enable the tracks under tracing to be shifted to obtain a predetermined relationship between the sequence of the n number of rotary heads and the sequence of the tracks traced by these rotary heads.
