Patent ID: 7280142

Claim:
A solid-state imaging apparatus, comprising: a frame-reading solidstate image pickup element for outputting an image signal, the image signal including a target pixel having first pixel data, a first peripheral pixel that is not adjacent to the target pixel and has second pixel data, a first adjacent pixel that is adjacent to the target pixel and has third pixel data, and an additional pixel that is either adjacent to the target pixel or not adjacent to the target pixel and has fourth pixel data; a first filter containing the target pixel and the first peripheral pixel; a second filter containing the first adjacent pixel and the additional pixel; a defective pixel detector for extracting the first pixel data, the second pixel data, the third pixel data, and the fourth pixel data and determining that the target pixel is defective if both of a difference between the first pixel data and the second pixel data is greater than or equal to a first threshold value and a difference between the third pixel data and the fourth pixel data is less than or equal to a second threshold value, wherein a determination that the target pixel is defective is based on both of said differences; and a defective pixel correction unit for correcting the first pixel data based on the second pixel data.
