Title:
IMAGING DEVICE AND METHOD FOR CONTROLLING THE SAME
Document Type and Number:
Japanese Patent JP2016118636
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform automatic focusing that suppresses a focus variation due to a deviation of a mounting position of a sensor.SOLUTION: An imaging device having a photometric sensor and range-finding sensor comprises: image data generation means that generates image data using the photometric sensor; specific color determination means that determines whether a pixel group has a specific color for each pixel group of the image data generated by the image data generation means; specific color block determination means that divides the pixel group into a block corresponding to a range-finding point having the range-finding sensors discretely arranged, and determines whether the block has the specific color depending upon whether an area occupying a specific color pixel group for each block is equal to or more than a prescribed ratio; and specific color focus means that focuses on the range-finding point of the range-finding sensor corresponding to the specific color block.SELECTED DRAWING: Figure 3
