Abstract:
1. An image capturing system that applies grayscale conversion to a video signal from an image capturing unit and outputs the grayscale-converted video signal, comprising: a second-grayscale-conversion-characteristic calculating unit that calculates a second grayscale conversion characteristic from a video signal to which a first grayscale conversion process has been applied by using a first grayscale conversion characteristic used to convert an M-bit video signal into an N-bit video signal, where M and N are integers and M is larger than N; a first-grayscale-conversion-characteristic correcting unit that corrects the first grayscale conversion characteristic by using the second grayscale conversion characteristic; and a first grayscale conversion unit that applies the first grayscale conversion process to the video signal by using the corrected first grayscale conversion characteristic.
