Mounting device and imaging processing method
A mounting device sets a processing region for super-resolution processing based on an approximate position of a main body portion of a component included in a mark image for use in obtaining a position of a fiducial mark and then performs super-resolution processing. Thus, the processing region for super-resolution processing can be appropriately set and prevented from becoming larger than necessary with respect to the main body portion of the component. Further, the processing region for super-resolution processing is determined using the mark image captured under an imaging condition different from that for the component image for use in super-resolution processing. Thus, the processing region can be appropriately set while the component image is kept under an imaging condition suitable for super-resolution processing. Therefore, the processing region for performing super-resolution processing can be set more appropriately, and the super-resolution processing can be efficiently performed. |

High density parallel proximal image processing
A distributed, parallel, image capture and processing architecture provides significant advantages over prior art systems. A very large array of computational 0 in some embodiments, matching the size of the pixel array—is distributed around, within, or beneath the pixel array of an image sensor. Each computational circuit is dedicated to, and in some embodiments is physically proximal to, one, two, or more associated pixels. Each computational circuit is operative to perform computations on one, two, or more pixel values generated by its associated pixels. The computational circuits all perform the same operation(s), in parallel. In this manner, a very large number of pixel-level operations are performed in parallel, physically and electrically near the pixels. This obviates the need to transfer very large amounts of pixel data from a pixel array to a CPU/memory, for at least many pixel-level image processing operations, thus alleviating the significant high-speed performance constraints placed on modern image sensors. |

Correcting pixel defects based on defect history in an image processing pipeline
An image signal processor may include a pixel defect correction component that tracks defect history for frames captured by an image sensor and applies the history when identifying and correcting defective pixels in a frame. The component maintains a defect pixel location table that includes a defect confidence value for pixels of the image sensor.

If a pixel is detected as defective, its defect confidence value may be incremented. Otherwise, the value may be decremented. If a pixel's defect confidence value is over a defect confidence threshold, the pixel is considered defective and thus may be corrected. If a pixel's defect confidence value is under the threshold, the pixel is considered not defective and thus may not be corrected even if the pixel was detected as defective. |
