1. An image pickup apparatus comprising:
- an image pickup portion that receives an incident light from an image-pickup object and performs a photoelectric conversion of the light; and
an image processing portion that performs a spatial filter process of removing a predetermined low-frequency component from a picked-up image output by the image pickup portion,wherein due to the spatial filter process performed by the image processing portion, a pixel brightness value of the picked-up image of a range of at least a predetermined distance from the image pickup portion becomes relatively greater than a pixel brightness value of the picked-up image of a second range of less than the predetermined distance from the image pickup portion.

15. An image pickup method for an image pickup apparatus having an image pickup portion that receives an incident light from an image-pickup object and performs a photoelectric conversion of the light, and an image processing portion that performs an image processing of a picked-up image, the method comprising the steps of:
-
outputting the picked-up image, and performing a spatial filter process of removing a predetermined low-frequency component from the picked-up image output by the image pickup portion, wherein due to the spatial filter process performed by the image processing portion, a pixel brightness value of the picked-up image of a range of at least a predetermined distance from the image pickup portion becomes relatively greater than a pixel brightness value of the picked-up image of a second range of less than the predetermined distance from the image pickup portion. - View Dependent Claims (16)
