Title: Character detecting and segmenting device
Inventor: SANO TSUTOMU
IPC: G06V10/20
Filed: 1982-05-27
Abstract: PURPOSE:To detect and separate a character pattern for each character, by deciding a block of the maximum area as a character within an observing region for each character and defining a fixed ratio of the maximum area as the reference value to decide the noise. CONSTITUTION:An XI pattern converting circuit 1 converts a bit pattern equivalent to a character into coordinates of black and white points for each row and delivers them to a block discriminating part 2. The part 2 compares successively two channels of the XI pattern. A block area calculating part 4 totals the number of black points, i.e., the difference between white and black point coordinates of the XI pattern corresponding to the same block number within a block number table 3. Then the area is calculated for each block. A noise block discriminating part 5 decides a block as a noise when the areas of other blocks are smaller than the reference value. A noise block eliminating part 6 eliminates noises in response to the result of decision given from the part 5.

Abstract: PURPOSE:To obtain a desired function by adopting constitution such that a composite image signal is inputted to a translucent function section provided with a Y/C separation circuit, a switching means intermitted by a translucent section indication signal and a 1st mixer thereby only adding a circuit of translucent function to a conventional telopper device singly. CONSTITUTION:In a figure, a block shown in an alternate long and short dash line is a telopper section and a block shown in broken lines is a section having an additional translucent function. A Y signal and a C signal are generated from a RGB signal at an encoder and a mixer (MIX4) is arranged to an external Y signal line prior to the mixture stage of the two signals. Then a switch (SW3) receiving an input, the inverse of Y signal being the result of separating the input video signal by the Y-C separation section is arranged on the other side. As a switching signal for the switch, the inputted inverse of Y signal is selected by an HT signal at the output of the SW 3 by selecting the signal itself (HT signal) of a part desired to be subjected to translucent processing, and both Y signals are mixed at the MIX 4. Thus, a video signal output being part of translucent picture of a personal computer is obtained by the HT signal.

IPC: G03B7/08
Filed: 1980-07-02
Abstract: PURPOSE: To obtain accurate shutter tranvelling completion signals by detecting the change of luminance corresponding to the closure of a shutter blade with a light detecting element.  
     CONSTITUTION: When light passed through the subdiaphragm 10 of a shutter used also as a diaphragm is made incident to photovoltaic element 12 and the charging quantity of a time constant capacitor 17 reaches the specified value, a transistor 21 is tuned off. Thus, power supply to a coil 22 is stopped and the shutter blade starts to close by the force of a spring. When the output of an operation amplifier 15 is reduced by the close of the subdiaphragm, the output CP2 of a comparator 32 is  turned to the L level and the output IN2 of an inversion circuit 36 is inverted to the  H level. Since other 2 input Q 1  and Q 2  to an AND gate 46 are held in the H level,  the output N2 of the AND gate 46 is inverted to the H level and the output OR1 of  an OR gate 43 also is turned to the H level, generating a shutter travelling completion signal.

Abstract: PURPOSE:To enable connection both to a digital data exchange(DDX) network and an integrated services digital network(ISDN) to be performed by connecting a DDX interface to a G4 interface ordinarily and connecting an ISDN interface to the G4 interface by a switching means when incoming to the ISDN interface is detected at a switching control means. CONSTITUTION:Since the G4 interface 10 is connected to the DDX interface 12 ordinarily, image information is inputted to the G4 interface 10 via the switching means 13 when it arrives at the DDX interface 12. Meanwhile, when the image information arrives at the ISDN interface 11, the switching control means 15 controls the switching means 13 by detecting the information, and the G4 interface 10 is connected to the ISDN interface 11, therefore, the image information is inputted to the G4 interface 10 via the switching means 13.
