Imaging pixels may be operated in a rolling shutter scanning mode. Charge signal that is generated on a first chip may be capacitively coupled to signal processing circuits on a second chip. A capacitor may be placed in the signal path that provides signal coupling between the chips and stores overflow charge from pixels that have been exposed to high light level illumination. This enables high dynamic range using only a single charge integration time. The pixel may include an in-pixel negative feedback amplifier. The chip-to-chip electrical connections between the first and second chips may be realized at each pixel as a hybrid bond with a single bond per pixel. Image sensors fabricated using this technology may have small size pixels, high resolution, high dynamic range, and a single charge integration time.

An imaging apparatus includes a camera shake correction unit which uses a coil and a magnet to move a movable portion including an image pickup device relative to a fixed portion. A position detection section detects the position of the movable portion. A setting section sets a resolving power of the detection of the position by the position detection section to a first or second resolving power which is a resolving power higher than the first resolving power and at which an amount of deviation from a target position is less than or equal to a pixel shift amount. A drive control section performs pixel shifts to move the movable portion with the second resolving power set by the setting section. A photography control section causes the image pickup device to perform exposures by timing of the pixel shifting and which composes images obtained by the exposures.

Methods and apparatus for compensating for bad pixels in a sensor array.

The system compensates for the location of the at least one bad pixel in the image for the first and second frames to output a processed image.
