Abstract
The present technology relates to an image processing apparatus, an image processing method, electronic equipment and a program which can remove cyclic noise from an image including the cyclic noise.An estimating unit configured to estimate cyclic noise components included in each image picked up under different exposure conditions for each image is included. The estimating unit estimates the cyclic noise components for each image through operation utilizing mutual relationship between the noise components under the exposure conditions. For example, the cyclic noise is flicker. The mutual relationship between the noise components may be expressed with a shutter function of the exposure conditions in frequency space. The present technology may be applied to an imaging apparatus.
