Abstract:
Technologies for managing access to image data streams generated by a plurality of image sensors of an image sensor array include a camera driver module. The camera driver module limits exposure to a user to all but one of the image sensors of the image sensor array. In some embodiments, the image sensor array may include a single primary image sensor that is exposed to the user and one or more secondary sensors that are not exposed to the user. In other embodiments, the image sensor array may include more than one primary image sensor and any number of secondary image sensors. In such an embodiment, only one of the primary image sensors are exposed to the user, and none of the secondary image sensors, if available, are exposed to the user. Other embodiments are described herein and claimed.
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.
