Abstract

PURPOSE: To obtain sharp pickup image for objective, by superimposing the result of external shape emphasis processing on mask picture.
CONSTITUTION: The processed digital picture 1 is made to the two dimensional Fourier transformation 3, and filtering operation is made at the filter multiplier 5a to reject noise components. The result is made to inverse Fourier transformation 6a, and the objective detection 8 is made based on the result and the advanced information. After that, the objective picture is enlarged 9 and this is taken as the mask. On the other hand, the signal transformed with Fourier 3 is made to filtering operation 5b and inverse Fourier transformation 6b is made. Further, the mask operation processing 10 by the mask mentioned before is made to this inverse Fourier transformation image, and picture is processed.
