Embodiment Construction

[0040] Hereinafter, embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0041] FIG. 1 is a block diagram showing an example of a functional configuration of an imaging device 100 according to an embodiment of the present invention. The imaging device 100 includes a lens 110 , a motor 120 , a motor driving circuit 130 , an aperture 140 , a driving circuit 150 , an imaging device 160 , a driving circuit 170 , a front end (F / E) processor 180 , a signal processor 190 and a system controller 195 .

[0042] The lens 110 collects incident light from a light source and reflected light from an object. The motor 120 is rotated according to a driving signal output from the motor driving circuit 130, thereby moving the lens 110 and adjusting a focal length and a focal position of a subject. The engine driving circuit 130 generates a driving signal to rotate the engine 120 based on the control of the system controller 195 and outputs...

Abstract

An imaging apparatus includes a defective pixel storing unit to store positional information of a defective pixel among pixels in an imaging device and pixel defect information indicating whether a defective pixel group including defective pixels includes the defective pixel related to the positional information; an image input unit to input an image; a defective pixel determining unit to determine whether each pixel in the input image is a defective pixel; a pixel sharing defect determining unit to determine whether the defective pixel is included in the defective pixel group; a pixel type determining unit to determine the type of each pixel in the input image; an interpolated pixel selecting unit to select surrounding pixels of the defective pixel; an interpolation value calculating unit to calculate an interpolation value of the defective pixel; ; and an interpolation value substituting unit to substitute the value of the defective pixel with the interpolation value.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application No. 2007-122127 filed in the Japan Patent Office on May 7, 2007, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an imaging device. Specifically, the present invention relates to an imaging device that corrects a defective pixel included in an image captured by using an imaging device, a defective pixel correcting device, a processing method in the device, and a program that causes a computer to execute the method. Background technique [0004] In recent years, imaging devices such as digital still cameras and digital still cameras have been widely used to take images of subjects. Also, imaging devices have been miniaturized and image quality in imaging devices has become higher. Also, pixel defects including white defects and black defects occur in solid-stat...
