摘要： PURPOSE: To obtain accurately the number of illuminant by adjusting the threshold value so that the difference in a level meter due to fluctuation of lightness is eliminated from the information of two areas of a continuous illuminants thereby finding out the regularity of the continuous illuminants.
CONSTITUTION: The level meter in an area 2 is recognized at first, the width 6 of the level meter is checked from left to right of the area, the change in the width and the variation in the position are checked so as to obtain the range of the size of the level meter. Then, the part within this range is checked lengthwise, the threshold value is increased until the illuminant separated at an interval having the regularity is obtained and when the illuminant separated by a prescribed interval is obtained, the length for one illuminant, the average value of the interval of the illuminants and the number are obtained, the length of the lighting part is obtained from the number, the length of the illuminant and the average value of the interval, the relation with the length of the lighted part of the level meter obtained at first is checked so as to decide the number of the illuminants.

摘要翻译：目的：通过调整阈值来准确地获得光源的数量，从连续光源的两个区域的信息中消除由于亮度的波动引起的电平表的差异，从而找出连续光源的规律性。构成：首先识别区域2中的电平表，从该区域的左侧到右侧检查电平表的宽度6，检查宽度的变化和位置的变化，以获得范围的电平表的大小。然后，长度检查该范围内的部分，增加阈值直到获得具有规则性的间隔的光源分离，并且当获得了以规定间隔分开的光源时，一个光源的长度，平均值获得发光体的间隔和数量，从数量，发光体的长度和间隔的平均值获得照明部的长度，与获得的液位计的点亮部的长度的关系首先检查以确定发光体的数量。

摘要： PURPOSE:To judge quickly and assuredly the ON or OFF state of each lightening object by setting an area enclosing each lightening object to detect the lightening area within the set area for each byte and obtaining said lighting area in the form of the number of bits by means of a conversion table. CONSTITUTION:The lighting position of each LED.lamp, etc. and the reference lighting area are previously stored for each cassette deck in the form of the reference data for recognition. Based on this reference data, the recognition is carried out. A processor 2 binary coding the image pickup signal sent from a TV camera 9 through a picture processing circuit 4 by means of the threshold value stored when the reference data is produced. This binary coded signal is stored to a picture memory. Then the processor 2 measures the LED lighting area within the same area as an area 25 stored in the picture memory by means of a lighting area measurement program. Then the ratio is obtained between the measured lighting area and the reference lighting area, i.e., the stored reference data. Then a lighting state is decided if the obtained ratio is larger than the fixed value. While an OFF state is decided for the lighting object if said ratio is smaller than the fixed value.

摘要： PURPOSE:To improve the operation process of the recognition of many kinds of continuous bodies which differ in individual shape, array interval, etc., by setting data on reference length between both ends and reference areas that individual shape bodies occupy. CONSTITUTION:For example, when the continuous body to be recognized is a level meter, the level meter is shot by a TV camera to detect a level meter reference point (left end) A' in a level meter reference detection area S from left to right, and its difference delta from reference data is calculated to correct an LED turn-on area measurement area T; and turn-on areas l1 and l2 are measured to calculate the area ratio to the stored reference turn-on area l of an individual LED, and the area ratio is compared with a predetermined specific value to perform the recognition.
