Document Type and Number:
Japanese Patent JP6818461
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To acquire multiple F-value images having F values different from each other, while suppressing increase in the amount of image data.SOLUTION: An imaging device 100 has an image pick-up device 104 for imaging an optical image formed by an optical system 102, an F value control section 111 for changing the F value, and a transmittance distribution impart section 103 for imparting transmittance distributions, different from each other, to the optical image or the image data generated by imaging, for each different F value. Image processing apparatus 106, 206 acquire an input image generated by imaging of an optical image where different transmittance distribution was imparted for each different F value, or an input image synthesizing the image data where different transmittance distribution was imparted for each different F value, and generate multiple F-value images corresponding to different F values, respectively, from the input image.SELECTED DRAWING: Figure 2
