Title: Catv receiver
Inventor: IZUMIYAMA TORU
IPC: H04N7/167
Filed: 1986-07-02
Abstract: PURPOSE:To receive no image even by selecting an adjacent channel by an ordinary television receiver and to effectively prevent a stealing glance by outputting the frequency converted television signal of the adjacent channel by attenuating a horizontal synchronizing part. CONSTITUTION:A trap circuit 11 is interposed between the output part of a device, namely a descrambler part 6 and an output terminal 10, a pulse (synchronizing with a key pulse) outputted from a driver part 8 is applied to the trap circuit 11 and operated while the pulse is fed. Accordingly, the trap circuit 11 is operated synchronously with the key pulse, so that the frequency converted television signal of the adjacent channel is scrambled similarly to the television signal scrambled and transmitted by a CATV broadcasting station by attenuating the horizontal synchronizing part. Thereby, the image can not be received even by selecting the adjacent channel by the ordinary television receiver and the stealing glance can be prevented.

Title: Identification method for line graphic
Inventor: SHIMATANI AKIRA
IPC: G06T7/60
Filed: 1990-06-14
Abstract: PURPOSE:To identify line graphics at high speed by means of saving labor even if plural line graphics are overlapped by identifying the line graphics through the use of a value obtained by means of determining the quantity of an evaluation scale for the judgement causes of line type regularity, continuity, unevenness, symmetry, a closing characteristic, a fetch characteristic and similarity. CONSTITUTION:In addition to five factors of line type regularity, continuity, evenness, symmetry and the closing characteristic which are quantitatively defined based on a total curvature function, two causes of similarity and the fetching characteristic are guided. A line graphic identification part 23 obtains a characteristic point and a segment element in an input line graphic. A line graphic shape judgement part 12 judges whether the inputted line graphic is a single graphic or the graphic having overlap. When the inputted line graphic has overlap, it is judged whether the graphic requires interpolation or not. When it is judged that interpolation is required, it is executed. A line graphic shape judgement part 15 extracts a segmentation candidate as to the graphic which does not require interpolation. An overlapped linear graphic characteristic analysis part 14 analyzes shapes as to respective segmentation candidates based on seven judgement causes and the line graphic is automatically segmented and identified. Thus, the line graphic having overlap can automatically be identified at high speed.
