Abstract:

An image sensor, suitable for resolving a high-resolution image, comprises an arrayed plurality of image sensor modules of moderate individual resolution. The high-resolution image is subdivided into contiguous sub-images, each of which is minified before being projected upon an image sensor module. This avoids bars of blindness between the fields of view of the image sensor modules, and also facilitates production and repair of the image sensor.
