Abstract: A hand-written character recognition apparatus with a personal dictionary preparation function has a character recognition unit for comparing an input hand-written character data with a registered standard dictionary to recognize a most similar character pattern, and a display unit for selecting and displaying a display font corresponding to the recognized character pattern, so that a personal peculiar character or simplified character inputted can be recognized. When a personal dictionary is to be registered, the character to be registered is inputted by hand-writing, the character recognition unit compares the input hand-written character data with the standard dictionary to recognize a similar character pattern, and the recognized character code of the standard dictionary is selected as the character code to be registered.

Abstract: Lower resolution video signals (10) having alternating odd fields (12) and even fields (14) are stored in an odd line memory 20A and an even line 20B, respectively. An interpolator 22 interpolates adjacent odd and even lines. A selector 24 cyclically selects odd, even, and interpolated lines in a pre-selected pattern, such as one of the patterns illustrated in FIGS. 1, 7, 8A-F, and 9A-F. By selecting even, odd, and interpolated lines, the number of lines per picture is increased to produce a higher resolution video signal (30).

Abstract: A system is provided for detecting closed contacts in a matrix switch made by using, for example, transparent conductive sheets. According to the present invention, switching elements are parallel-connected to resistors which are used to pull up the electric potentials of sense lines. These switching elements are suitably turned on to expedite the electric potentials of the sense lines. This enables the detection of closed contacts to be done correctly even when an operational speed is increased.
