PURPOSE:To enable a user to simply end intuitively control the degree of depth of field. CONSTITUTION:A distance (focus range FR) where the in-focus states are secured before and after a focal position is set so that an in-focus area can be previously set in an image. Meanwhile, a defocus range of an out-focus state is dispersively set in a simple way at the diameter value of a disperse circle (1C, 2C, 3C, 4C... 7C...) in the individual depth ranges (S1, S2, S3, S4,... S7...). Thus, a user freely sets the degree of expansion of 8 disperse circle so that an image of a desired out-focus state is obtained. |
