Abstract: An imaging system may have a pixel array that includes a first group of pixels and a second group of pixels that generate image signals in response to light received from a scene. Image signals generated by the first group of pixels may be read out using a first skipping pattern and/or binning factor and image signals generated by the second group of pixels may be read out using a second skipping pattern and/or binning factor. The first and second skipping patterns and/or binning may be different and may be weighted based on the amount of image data that is available for different portions of the scene. An image may be generated based on the image signals that are read out from the first and second groups. Perspective correction operations may be used to correct for perspective distortion in the image.

Abstract: An image sensor may include an array of image pixels arranged in rows and columns. Each image pixel arranged along a column may be coupled to a pixel column line. Each pixel column line may be coupled to column memory circuitry via a respective analog-to-digital converter circuit. The column memory circuitry may include multiple column memory circuits, including a spare column memory circuit. If none of the column memory circuits are defective, the spare column memory circuit is idle. If one of the column memory circuits is defective, the spare column memory circuit is engaged to bypass the defective column memory circuit. Configured in this way, the column memory circuitry is provided with column-wise memory repair capabilities.

Abstract: An imaging system may include an image sensor array and column randomizing multiplexers. The imaging system may include a data output circuit and image readout circuitry such as analog amplifiers, analog-to-digital converters, and memory circuits. The column randomizing multiplexers may include a first column randomizing multiplexer between the image sensor array and at least some of the image readout circuitry. The first column randomizing multiplexer may randomly connect columns of the image sensor array to the image readout circuitry. The connections made by the first column randomizing multiplexer may be randomized as each row of the image sensor array is read out. The column randomizing multiplexers may include a second column randomizing multiplexer between at least some of the image readout circuitry and the data output circuit. The second column randomizing multiplexer may reorder image data for the image readout circuitry.

Abstract: In this image processing device, an image processing portion 102 performs a predetermined pre-processing on first image data and outputs it as second image data. A judging portion 104 that judges the degree of importance of the first image data on the basis of the characteristics of a subject that is included in the first image data. A reducing portion 105 reduces the data amount of the second image data in accordance with that degree of importance and outputs it as third image data. According to this image processing device, by reducing the data amount of the second image data in accordance with the degree of importance of the first image data, it is possible to achieve greater reductions in the data amount as the degree of importance decreases. As a result, it is possible to more efficiently reduce the power consumption and time required when transferring image data after data reduction.
