Variable integration time function

By controlling the clock pulse to the INT terminal, the integration time for each pixel can be changed to any length that is an integer mul-

tiple of one readout period. When the clock pulse at the INT terminal is set to “high” at the pixel signal readout timing, then no signal is

output from that pixel (see below). This allows the signal charge to continuously accumulate in that pixel as long as no signal is output. For

example, when the integration time of one readout period is 100 ms and this function is used to output a signal from a pixel once every 3

readout periods, then the integration time of that pixel will be 300 ms. Using this function to lengthen the integration time of certain pixels

makes it possible to effectively detect spectral signals of weak wavelength components.

(Concept view showing the settings to double, triple and quadruple the integration times at channels 2, 3 and 4, respectively, by using

the variable integration time function on the basis of the integration time at channel 1.)
