摘要： An image signal is input to two LPFs having different transmission characteristics. A selector chooses one of outputs of the respective LPFs and delivers the chosen output to a gamma correction circuit. The switching of the selector is controlled by a filter control circuit. In the filter control circuit, a comparator compares an exposure time E of a current frame with a threshold value R. The selector is controlled so as to select an output of one of the LPFs that has a lower cutoff frequency and a greater noise component elimination effect than the other LPF does if the exposure time E is longer than or equal to the threshold value R.

摘要： An image signal processing apparatus solves a problem of an increase in noise component contained in an image signal due to the gamma correction when a signal level is in a region where a slope of conversion characteristic is sharp, which problem has been detected in an image signal processing apparatus including gamma correction processing performed for achieving nonlinear conversion. The image signal is input to each of LPFs 40 and 42 which differ in transmission characteristic, and a selector 44 selects either one of outputs from the LPFs to send the selected output to the gamma correction circuit. The switching by the selector 44 is controlled by the filter control circuit 32. In the filter control circuit 32, a comparator 60 compares a signal level of an object pixel with a threshold value R. In the case where the signal level of the object pixel is in the region where the slope of conversion characteristic is sharp (less than R), the selector 44 is so controlled as to select the output from the LPF 42 which has a lower cutoff frequency and a larger noise component elimination effect as compared with the LPF 40.
