Document Type and Number:
Japanese Patent JP6740666
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To properly perform AF processing without regard to the color of a subject, in an imaging apparatus comprising a single-plate-type multilayered image pickup device.SOLUTION: A single-plate-type multilayered image pickup device 32 is obtained by laminating and arranging plural photoelectric conversion layers 62B, 62G, and 62R in this order on a silicon substrate 75. Pixels for focus detection PB, PG, and PR are arranged in the respective photoelectric conversion layers. The pixel signal mean values of the photoelectric conversion layers 62B, 62G, and 62R are compared with each other and the pixel for focus detection of a photoelectric conversion layer which outputs the largest mean value is used to execute the AF processing.SELECTED DRAWING: Figure 6
