Abstract

A camera system including a plurality of image capture devices and supporting output of data from data storage arrays of each image capture device in a segment-by-segment manner, with output lines arranged in an interleaved manner so that interleaving is automatically achieved without complex image processing. The interleaved image or video output of such a camera system will appear as a three dimensional image when viewed through a screen of lenticular lenses.

Claims

1. A camera system including:

n image capture devices having;

respective n lenses arranged such that optical paths of each of said n lenses are substantially parallel to each other and each of said n lenses are located along a substantially perpendicular axis to said optical paths;

a respective n storage arrays, said n storage arrays either being integrated within said n image capture devices or being connected thereto for receiving image output information therefrom, wherein said n storage arrays have output connections arranged for retrieval of segments of a plurality of images captured by said n image capture devices;

an array of image sensor elements for each of said n image capture devices comprising or connected to a dedicated storage array for receipt of information from said array of image sensor elements;

said output connections being in an Interleaved arrangement such that the segments of the plurality of images are interleaved between each other to produce an interleaved stereoscopic image, and to access segments of each of the dedicated storage arrays interleaved between segments of each of the other arrays; and

wherein each said dedicated storage array has P rows and Q columns, a first set of P address lines being connected to the P rows and a second set of Q/n address lines and corresponding Q/n output data lines being connected to an equally spaced selection of Q/n of the Q columns, wherein said output data lines from each of said n image capture devices are interleaved to produce an interleaved image of P rows and Q columns.

2. A camera system according to claim 1, including a shared storage array connected to receive information from each of the plurality of image capture devices, wherein the connections between the image sensor elements and the shared storage array are arranged such that the shared storage array will receive information from sectors of each array of image sensor elements of the plurality of image capture devices interleaved with information from sectors of other image sensor arrays of the plurality of image capture devices.

3. A camera system according to claim 1, including a common storage array organised as a set of distinct sectors each connected to receive information from one of the plurality of image capture devices, wherein output data line connections to the sectors of the common storage array are interleaved such that the information output via the output data lines comprises interleaved image segments from the plurality of digital image capture devices.

4. A camera system according to claim 1, including a plurality of lenses each in optical alignment with a respective digital Image capture device comprising an array of image sensor elements, the image sensor elements being connected for transfer of information to respective cells of a digital storage array, wherein the storage array has address line and output data line connections enabling data retrieval directly from the cells of the storage array either for transfer to non-volatile storage or for transmission, the arrangement of the physical connections between the elements of the array of image sensor elements and the cells of the storage array and the output data lines being such that the information output via the output data lines comprises interleaved image segments from the plurality of digital image capture devices.

5. A camera system according to claim 1, wherein one of the image capture devices includes non-interleaved output connections which are switchably selectable to enable selection between output of a non-interleaved image from a single image capture device and output of an interleaved image from the plurality of image capture devices.

6. An image capture device having a respective lens, for use in a camera system including a plurality n of such capture devices with the respective plurality of lenses being in an arrangement such that the optical paths of the lenses are substantially parallel to each other and the plurality of lenses are located along a substantially perpendicular axis to the optical paths and with their outputs connected in an interleaved manner to generate interleaved stereoscopic output images having P rows and Q columns of pixels, the device including an array of image sensors also having P rows and Q/n columns and a storage array having P rows and Q/n columns connected to receive information from the array of image sensors.
