Embodiment Construction

[0022] As discussed above, improved capabilities of electronic devices are beneficial and desirable. In particular, image sensor modules that support higher frame per second (FPS) processing and / or larger megapixel (MP) sensors are beneficial. For example, larger MP sensors are able to capture images with higher resolution or finer detail. Furthermore, higher FPS in electronic devices supports smoother video capture. However, larger MP sensors and / or higher FPS support may require higher throughput. For example, image signal processor (ISP) throughput may need to be substantially increased to support the 30FPS output rate of a 12MP sensor.

[0023] Designing an image signal processor (ISP) with a substantial increase in throughput can be time consuming and very expensive. However, the systems and methods disclosed herein allow parallel processing by a combination of two or more "off-the-shelf" image signal processor (ISP) modules in order to achieve the desired throughput. ...

Abstract

An electronic device for parallel image processing using multiple processors is disclosed. The electronic device includes multiple image sensors for providing image data. The electronic device also includes multiple processors for processing segmented image data to produce processed segmented image data. Each processor is dedicated to one of the image sensors. A multiple processor interface is also included. The multiple processor interface maps the image data to the processors, segments the image data to produce the segmented image data and synchronizes the segmented image data to processor clock rates.

Description

technical field [0001] The present invention generally relates to electronic devices. More particularly, the invention relates to parallel image processing using multiple processors. Background technique [0002] In recent decades, the use of electronic devices has become widespread. In particular, advances in electronics technology have reduced the cost of increasingly complex and useful electronic devices. Cost reductions and consumer demands have proliferated the use of electronic devices to the point of near ubiquity in modern society. As the use of electronic devices expands, the demand for new and improved features of electronic devices also grows. More specifically, electronic devices that perform functions faster, more efficiently, and with higher quality are generally sought. [0003] Some functions can be data-intensive (eg, image processing), requiring substantial processing resources to complete in a desired amount of time. However, electronic devices such a...
