Document Type and Number:
Japanese Patent JP5791952
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic endoscope apparatus capable of appropriate correlation double sampling processing even when a distal end of an insertion part of the endoscope is used in various temperature ranges.SOLUTION: The electronic endoscope apparatus 1 includes: a CCD 22; a temperature sensor 24 for detecting the temperature of the distal end 11a; a correlation double sampling section 51 provided for a body portion 12 to take out a signal component from an image signal output from the CCD 22; a timing generator 55 for generating a sample hold signal to operate the correlation double sampling section 51 and a drive pulse signal to drive the CCD 22; and a CPU 44 for adjusting, based on the temperature detected by the temperature sensor 24, the timing of the sample hold signal or drive pulse signal generated by the timing generator 55.
