Title:
IMAGE PROCESSING DEVICE, IMAGE CAPTURE DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/091854
Kind Code:
A1
Abstract:
An image processing device equipped with a solid-state image sensor provided with a light-receiving surface upon which pixels for detecting a phase difference and pixels for imaging are mixed, an image capture device provided with the image processing device, an image processing method in which the image capture device is used, and an image processing program, are used to appropriately correct an output signal for pixels for detecting a phase difference to obtain a high-quality captured image. A digital signal processing unit (17) extracts a decision block for each of a predetermined number of pixels centered on pixels to be corrected (S1). If an edge of a subject image exists in each decision block (S3: YES), and the direction of said edge is orthogonal to a phase difference detection direction of pixels for detecting a phase difference (S5: vertical direction), and said edge overlaps with the pixels to be corrected (S6: YES), interpolation correction is performed on the output signal for the pixels to be corrected inside said block (S7).
