摘要： PURPOSE:To obtain a circuit eliminating glitch to be produced at switching of polygonal lines of a ramp voltage generator by extracting a digital output corresponding to each input voltage at each register in an integration type AD converter consisting of the ramp voltage generator using polygonal lines. CONSTITUTION:In applying AD conversion by a ramp voltage V0, the ramp voltage V0 rises with a slope proportional to a current source i0 at a time t1, a counter K1 counts a clock CLK. The ramp voltage V0 rises with a slope proportional to a current source i1 from a time t4 to t5 and a counter K1 makes count by the clock CLK. The ramp voltage V0 rises with a slope proportional to a current source i2 from a time t7 to t8 finally and the counter K1 counts by using the clock CLK. Comparator groups C1, C2,...Cn compare the ramp voltage with input voltages V1, V2...Vn and when they are coincident, the content of the counter K1 is set to registers L1, L2...Ln.

摘要： PURPOSE:To attain effectively the desired accuracy for a current source of a lamp voltage generator by comparing the input voltage with the lamp voltage given from the generator for broken line-shaped lamp voltage which contains switch groups and an integrator and extracting the digital output corresponding to each input voltage with the accuracy necessary for each register. CONSTITUTION:A switch S0 is opened at a time point t0 and a switch S1 is closed for a section of t1. The lamp voltage (y) rises up with a slope proportional to the courrent value I1 by an integration circuit (OP and C). A counter K1 starts counting with a clock CLK and produces the digital value corresponding to the lamp voltage value. the contents of a counter K are set to register groups L1-Ln when coincidence is obtained between the input voltages V1-Vn and the lamp voltage respectively. The switch S1 is opened at a time point (t0+t1) and the switch S2 is closed for a section of t2. The voltage (y) rises up in proportion to the value I2, and the counter K1 is shifted down by a shift signal SFT by an amount equivalent to the difference of weight between current values I1 and I2.

摘要： A character pattern recognition system is disclosed in which an unknown input pattern of character and a standard pattern of character are described and maintained in the form of a sequence of Freeman direction codes. One-to-multiple and multiple-to-one correspondence is permitted between the codes, to obtain a specific correspondence between them in which the sum of the difference between direction codes is minimum, so that the minimum value of code difference is used as a measure of determining the similarity between the two patterns.

摘要： PROBLEM TO BE SOLVED: To resolve a conventional problem of mixed noises in a digital voice signal processing built-in type eyeglass device, by comparing a display symbol with stored symbols to recognize it, and by stereoscopically displaying the recognized symbol on a transparent medium such as liquid crystal. SOLUTION: An analog-to-digital converter 101 digitizes an input analog voice signal. A voice recognition processing part 102 compares and collates the digitized voice signal with standard symbols previously stored in a standard memory 103 to decide a recognition voice, and converts the recognition voice into a display symbol having a given lump. The display symbol is sent to a display driver 104 so that the display symbol in one-to-one correspondence to the input analog voice signal is displayed on a stereoscopic display device 105. That is, the digital signal processing processes and stores a frequency characteristic of the input voice signal, converts the signal into the display symbol having the given lump, compares the display signal with the stored symbols to recognize it, and stereoscopically displays it on a transparent medium such as liquid crystal.
