Abstract:
1. An image pickup apparatus comprising: an image pickup element configured to obtain an image of an object, the image of the object including a plurality of pixels; an extraction unit configured to extract, from the image pickup element, pixels that have an output value that is equal to or more than a predetermined value, wherein a median value is obtained by performing median filtering with respect to each pixel of the image of the object and the output value for each pixel is obtained by subtracting the median value from each pixel of the image of the object; a setting unit configured to set a pixel among the extracted pixels as a target pixel; a determination unit configured to determine whether a condition that a predetermined number or more of the extracted pixels that have the same output value as that of the target pixel, irrespective of a color received by the target pixel, are continuously adjacent to one another in a same direction is satisfied; a storage unit configured to store, in a case that the determination unit determines that the condition is satisfied, data that indicates the continuously adjacent pixels are target pixels to be corrected and further configured not to store, in a case that the determination unit determines that the condition is not satisfied, the data that indicates the continuously adjacent pixels are the target pixels to be corrected; and a correction unit configured to correct signals output from the target pixels.
