Abstract: A pixel defect correction device includes: a defect determining section determining whether a pixel of interest of an image, in which pixels each having a pixel value are arrayed in a two-dimensional manner, is a defect of the image; a gradient detecting section detecting a gradient or an edge in a processing region, which includes pixels with the pixel of interest in the middle, based on values of at least peripheral pixels around the pixel of interest which are included in the processing region; a correction value acquisition section selecting a pixel, which is used for acquisition of a correction value of the pixel of interest, according to the detected gradient or edge and acquiring the correction value from a value of the selected pixel; and a defective pixel replacing section replacing the value of the pixel of interest with the correction value when the pixel of interest is determined to be a defect.

Abstract: A pixel defect detection and correction device includes: an average value acquisition section that acquires an average value of pixel values of adjacent pixels with different colors excluding a pixel whose defect is to be detected, which is a pixel of interest, in a processing region where adjacent pixels with the same color and adjacent pixels with different colors are arrayed with the pixel whose defect is to be detected in the middle; and a defect determining section that determines whether the pixel whose defect is to be detected is defective on the basis of at least the average value. The defect determining section determines whether the pixel whose defect is to be detected is defective by comparison of the pixel value of the pixel whose defect is to be detected, the average value of adjacent pixels with different colors, and a designated different-color pixel threshold value.

Abstract: Disclosed herein is a solid-state imaging apparatus including: a pixel array section having pixels laid out two-dimensionally to form a matrix to serve as pixels each used for detecting a physical quantity; an AD conversion section, which stands for an Analog to Digital conversion section, configured to carry out an AD conversion process on an analog pixel signal read out from the pixel array section; and a control section configured to control the AD conversion section on the basis of register values stored in a register, wherein in accordance with a clock frequency used for processing the pixel signal, the control section sets output bit count information expressed by one of the register values to serve as information used for setting an output bit count for the AD conversion process.
