Title:
METHOD AND DEVICE FOR READING RADIOGRAPH INFORMATION
Document Type and Number:
Japanese Patent JPH02272529
Kind Code:
A
Abstract:

PURPOSE: To set the best read conditions and image processing conditions by determining the read conditions or image processing conditions according to the characteristic value of a condition setting image signal which constitutes the remaining histogram area after a 1st area between the signal maximum value of a histogram and a threshold value which is a specific quantity less than the maximum value and a 2nd area between the signal minimum value and a threshold value which is a specific quantity larger than the minimum value are removed from the histogram.

CONSTITUTION: An image signal which is extracted from a preread image signal Sp is sent to a histogram generation part to generate a cumulative histogram. In this case, the area between the signal maximum value and the threshold value which is the specific quantity less than it and the area between the signal minimum value and the threshold value which is the specific quantity larger than the minimum value are removed from the histogram and the read conditions and image processing conditions are determined according to the characteristic value of the image signal which constitutes the remaining histogram area. Consequently, the best read conditions and image processing conditions can be set.
