摘要:
An image processing apparatus which eliminates influence of motion of background and performs stable text-image cutout at a high extraction rate. In the apparatus, a block divider 20 divides image data in frame units into blocks of a predetermined size. A DCT unit 24 performs orthogonal transformation on each divided block, and a harmonic coefficient calculator 25 extracts data for judging whether or not the block is a character area. A still-block detector 26 compares the data with data of a corresponding block after orthogonal transformation in a previous frame, judges whether or not the difference between these data is small or large, and outputs the result of judgment. An attribute judgment unit 23 judges whether or not the block is a character area, based on the data from the harmonic coefficient calculator 25 and the data from the still-block detector 26, and outputs the result of judgment.

A color display apparatus, such as a color liquid crystal display apparatus, is composed of a multiplicity of sub-pixels each designed for displaying one of a plurality (k) of mutually different mono-colors and arranged in rows and columns so as to form pixels each with a plurality of mutually adjacent sub-pixels. The sub-pixels and pixels are so arranged that a number n given by dividing a total number of sub-pixels arranged in a row or column with a total number of pixels arranged in the row or column is set to satisfy: 1

A character recognition apparatus and method for recognizing an unknown character by comparing strokes of the input character with stroke information stored in a dictionary. Each stroke of the input character is classified into one of plural categories according to stroke direction. The classified input strokes are rearranged into groups of strokes having the same classification. The degree of analogy between rearranged input strokes and stroke information stored in the dictionary for each group of similarly classified stroke group is calculated based on stroke length, and a maximum analogous element for each input stroke according to the calculated degree of analogy is detected. The detected maximum analogous elements are summed together, and the character whose sum is maximum is output as the identity of the unknown input character.

Character recognition method and apparatus according to the present invention comprises the partial pattern dictionary which classifies and registers partial patterns of characters to be recognized in accordance with direction data of strokes and the partial pattern composition dictionary which classifies and registers dictionary characters in accordance with the partial patterns. When a character image to be recognized is inputted, each stroke is converted into direction data. The partial pattern dictionary is searched by using the attained direction data and divides the character image to be recognized into a single or plurality of partial patterns. The partial pattern composition dictionary is searched by using the partial patterns attained in the above-described way. A dictionary character is thus attained as the result of recognition.

A web information processing apparatus (100) displays a screen for designating a program to be associated with a web page and registered if, for example, a registration request is input from a user when the web page is being displayed. Then, information specifying the designated program and information specifying the web page being displayed are linked and registered (105). The registered information is used to detect a web page linked to the program being viewed and (if necessary) to display the web page.
摘要:
A target value of a contrast ratio of an image display apparatus is set, and the number of levels, among which the luminance of a backlight is changed over, and each level of luminance are decided according to the target value of the contrast ratio. The backlight is made to emit light at the individual levels of luminance of the backlight thus decided, and at the same time, the image display apparatus is made to display a predetermined color chart thereon, so that color measurement is thereby carried out, and calibration is carried out at each level of luminance of the backlight based on a color value thus measured. The calibration is carried out only on an appropriate number of levels of the luminance of the backlight required to achieve the target value of the contrast ratio.
摘要:
A classification information setting method for classifying contents into series comprises: a similarity determination step for determining a similarity between first contents classified into a series and second contents unclassified yet; and a classification setting step for setting, in case the similarity exists, classification information related to the first contents, as classification information for the second contents. At the similarity determination step, the similarity is determined by comparing text data contained in the first contents and text data contained in the second contents.
摘要:
There is provided a broadcast receiving apparatus having a broadcast receiving unit. The apparatus includes: an instruction receiving unit which receives a broadcasting type selection instruction or a channel number selection instruction, and a control unit which, when the instruction receiving unit receives the broadcasting type selection instruction, controls the broadcast receiving unit to receive a broadcast wave specified by a combination of a current channel number and a type of broadcasting corresponding to the received selection instruction if an elapsed time from latest reception of a channel number selection instruction is not more than a predetermined time, and receive a broadcast wave specified by a combination of a type of broadcasting corresponding to the received selection instruction and a default channel number associated with the type of broadcasting if the elapsed time from the latest reception of a channel number selection instruction is more than the predetermined time.
