Title: Image reader
Inventor: ERIKAWA AKIHIKO
IPC: H04N1/04
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To accurately read a high density image by improving the precision of an arithmetic setup operation. SOLUTION: Upon the receipt of a preliminary scanned image data, it is determined whether or not a density of a film image is high (step 406), and when the discrimination result is negative, a read-out condition at fine scanning is calculated (steps 408, 410). However, when the discrimination result is affirmative, increase in a light receiving amount of an area CCD of a scanner with respect to a transmitted light of the film image is added as a read-out condition at the time of second preliminary scanning and the result is stored in cross reference with a frame number (step 412).  In the case of presence of an image discriminated to undergo preliminary scanning again (affirmative in the step 420), the read-out condition at the second preliminary scanning in the step 412 is informed to the scanner (step 422) and a read-out condition at fine scanning is calculated from image data obtained by the second preliminary scanning (step 428).

IPC: F02M25/07
Filed: 1990-07-06
Abstract: PURPOSE:To start a diagnosis in a stage wherein the number of times of measurement of parameters is small and thereby to enable early determination of abnormality or normality by changing a determination reference value in accordance with the number of times of measurement of the parameters. CONSTITUTION:A parameter measuring means 1 which determines sequentially values of parameters changing in accordance with the presence or absence of abnormality, an averaging means 2 which averages the determined parameters, a determination reference value setting means 3 which sets a determination reference value in accordance with the number of measurement of parameters and abnormality determining means 4 which compares the average value of the parameters with the determination reference value and determines the presence or absence of the abnormality, are provided. In consideration of the distribution of nonuniformity in the parameters, the determination reference value is set so that false determination of either one is excluded. When the number (n) of times of measurement is 1, for instance, the probability that false determination as abnormality is made when a state is normal is almost 0, if a determination reference value NG1 is set, and determination is made as abnormality only when the state is abnormal absolutely. When the number of times of measurement is small, it sometimes happens that the determination as abnormality is not made even when the abnormality occurs, to the contrary, but it can be determined as abnormality without fail when the number of times of measurement is increased.

Filed: 1989-07-13
Abstract: PURPOSE:To attain original reading and correction with stability and high accuracy by fetching a data from picture information with a picture fetch circuit at a time interval, using an arithmetic unit to compare the data with a reference data, discriminating the stable light source and adopting a lamp voltage and the gain of an amplifier at that time. CONSTITUTION:When a light source lamp 3 is lighted, an image sensor 5 receives picture information lighted by the lamp 3, converts the information into an electric signal and the signal is amplified by an amplifier 6. The data fetched by a picture fetch circuit 8 from the output is compared with a reference data at an arithmetic unit 10 and detects the difference. When the difference exceeds a permissible value, the data from the picture information inputted by the image sensor 5 again at a prescribed time interval is fetched, compared with a reference data by the arithmetic unit 10 to detect the difference. Thus, the data fetch and comparison are repeated and when the difference is a permis sible value, the voltage of the lamp 3 and the gain of the amplifier 6 are adopted as the data the stable luminous quantity to apply the original reading and correction. Thus, original read and correction with high accuracy are attained.

Title: Adaptive digital signal differentiating filter device
Inventor: OOMURO TAKASHI
IPC: H03H21/00
Filed: 1981-11-09
Abstract: PURPOSE:To provide a filter with adaptability of response by using a transversal filter so that even when an input signal varies abruptly, the rate of the variation is estimated. CONSTITUTION:A digital integrator 4 integrates an input signal X to obtain a digital signal W. A load on a transversal filter 5 is determined by an external input signal H. A minimum error forecasting device 6 inputs the difference signal E between the input signal X and an output signal Y of the filter 5, and then adjusts the signal H for the coefficient value of the filter 5 so that the square of the signal E is minimized a certain time later, thereby feeding it back to the filter 5. Since the coefficient of the filter 5 is adjusted so that the signal E is nearly 0 the certain time later and the signal W is obtained by integrating the signal X, the filter 5 is a filter for differentiating the signal W eventually. For this purpose, the input signal X is inputted to a transversal filter 7 having the same coefficient, outputting the differential signal V of the signal X.
