Title:
IMAGE PROCESSING APPARATUS, IMAGING APPARATUS, IMAGE PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2022106638
Kind Code:
A
Abstract:
To provide an image processing apparatus that can reduce an influence of a subject other than a detection object and a texture of a background on subject detection to perform the subject detection with higher accuracy.SOLUTION: An imaging apparatus acquires an input image with a lens unit 101 and an image pick-up device 141 (S200), and performs subject detection (S201). The imaging apparatus calculates a degree of reliability of the subject detection and compares the degree of reliability with a threshold (S202). When the degree of reliability of the subject detection is less than the threshold, the imaging apparatus executes defocus calculation processing (S203) and background area determination processing (S204). The imaging apparatus executes low-pass filtering processing on the determined background area (S205) to reduce a high frequency component of the background area before performing the subject detection again (S206).SELECTED DRAWING: Figure 2
