信号補正方法及び信号補正装置
Document Type and Number:
Japanese Patent JP3606898
Kind Code:
B2
Abstract:
A method and apparatus for performing dark signal correction on a photoelectric conversion device. A flow of light to the device is alternately conducted and interrupted (103). The device generates an intermixed signal (104) while the flow of light is conducted to the device, the intermixed signal including a desired signal intermixed with an unwanted dark signal. The device generates a dark signal alone (105) while the flow of light to the device is interrupted. The dark signal alone is filtered (106) to produce a filtered dark signal. The filtered dark signal is subtracted (107) from the intermixed signal to produce a corrected signal, which is representative of the desired signal.
