摘要： An image processing system wherein for an inputted composite image composed of a line image and a dither image, both a line image processing and a dither image processing are carried out in parallel, and one of the processed results as selected in accordance with the image region discrimination result. The dither image processing is carried out through data conversion for calculating multivalued gray scale image from the inputted image data, gray scale data conversion for adjusting the gray scale image data so as to match an output device and obtaining such adjusted gray scale image data, and re-binarization for re-binarizing the gray scale image data after subjected to the gray scale conversion. The image region discrimination for discriminating if an image region is of a line image of a dither image is carried out based on a ratio of the number of black or white pixels within the region to the contour line length within the range. In ordered dither image through a screened type dither matrix is discriminated in accordance with a correlation between adjacent pixel trains each having a predetermined number of pixels.

摘要： An image display apparatus that can ease the man-machine interaction when a user searches for a document in an electronic filing system, for example, through the image display apparatus. In a conventional electronic document filing system, it has been difficult to search for a document by inspecting or looking at the original document images shown on an image display screen. The difficulty comes from the lack in a capability of controlling the instantaneous display speed, an appropriate feedback to the user to synchronize the image paging, and a capability of showing the direction of paging. The image display apparatus disclosed here has a tactile feedback mechanism that tells the user the time a new image page is shown and that also tells him/her other status of the apparatus, like how busy it is, in terms of a tactile signal to the user's fingers. The mechanism is installed in a mouse-like pointing device that tells the apparatus the speed of paging. By using this, the user can control the paging speed spontaneously and at the same time he/she can feel the paging through the tactile feedback, in addition to a kind of sound effect.

摘要： A character stream search system using an FSA for determining at a time whether or not a plurality of character streams as search objects exist in a search character stream which undergoes a search operation and which comprises a plurality of characters expressed with codes. In the system, a collation is conducted between the search character stream and a search object character. In a case where there exists a matched search object character as a result of the collation, a state transition is carried out of a predetermined state indicated by the FSA. In a case where there does not exist a matched search object character, a failure processing to effect a state transition to a transistion destination which is determined in association with the configuration of the FSA. The following processing is completed at a count which is a predetermined upper-limit value for each character undergone the search operation.

摘要： Color image processing method and apparatus for suppressing side effects of a chrominance emphasizing process are provided. A chrominance C of an original color image is detected by a chrominance detector. A luminousness V of the original color image is detected by a luminousness detector. A parameter selector selects chrominance conversion parameters on the basis of the chrominance C and luminousness V to generate a selected parameter. A chrominance converter executes the chrominance conversion by chrominance conversion parameters a to i. It is possible to suppress a side effect such that the color deviation becomes conspicuous in a portion of small chrominance and luminousness due to the execution of the chrominance emphasizing process. Thus, image data of a high quality can be obtained.

摘要： A compact character string retrieving system capable of producing correctly the result of matching without omission even upon occurrence of multiple matching in which a plurality of search terms are matched for one character string by a finite automation. A destination state for transition brought about by a trailing character of the search term is newly created instead of an initial state. A transition table storage stores the destination state. On the basis of the source state number and a specified pattern character code, the destination state number is read out from the state transition table storage. When the state number read out represents the destination state of the transition brought about by the trailing character of the specified pattern character string, an identifier thereof is outputted. The identifiers of the search terms matched are each represented by one bit information, and a group of corresponding flags is stored in one slot. Multiple matching can be performed without omission. The character string retrieving system is implemented in a reduced size.

摘要： An apparatus for positioning is characterized by the fact that the circuit for generating a reference velocity, the existence of which is primarily responsible for the disadvantages in the conventional apparatus for positioning by analog feed-back of the velocity, is eliminated and a data processing unit is substituted for this circuit. Thus, the positioning is controlled by a group of predetermined reference velocity values stored beforehand in the memory of the data processing unit.
