Solution Overview
Problem
Conventional mobile devices face challenges in fitting high-resolution and 3D camera systems due to size and cost constraints, as well as increased power consumption and resource intensity, particularly when incorporating auto-focusing mechanisms.
Innovation Solution
A shared image processing circuitry is used between multiple imaging elements, such as front and rear-facing cameras, to manage and process image data efficiently, reducing the overall size and power consumption of the camera module by combining imaging elements into a single module with shared circuitry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution cameras with auto-focusing mechanisms are provided, then image quality and functionality are improved, but device size increases
Solution Approach 1:
The patent combines multiple imaging elements (first and second cameras) into a single integrated camera module with shared circuitry. The first imaging element captures images at a first resolution while the second imaging element captures images at a second resolution, and both share common image processing circuitry including auto-focusing mechanisms. This merging approach enables high resolution imaging capability while reducing overall device size compared to providing separate dedicated camera assemblies for each resolution level.
Solution Approach 2:
The shared image processing circuitry serves multiple functions by processing images from both the first and second imaging elements. The auto-focusing mechanism can operate for both cameras, and the image processing unit can handle images at different resolutions through the same hardware pathway. This multi-functionality reduces redundancy and allows high resolution imaging capability to be achieved without proportionally increasing device size.
2Adaptability or versatility
If multiple high resolution cameras are provided, then functionality is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple imaging functions into a single camera module where the first and second imaging elements share common support structure, lens assemblies, and image processing circuitry. By providing a shared auto-focusing mechanism and common image processing unit, the manufacturing cost is reduced compared to producing separate dedicated camera assemblies for each imaging element, while still enabling versatile functionality including high resolution imaging and standard resolution imaging.
Solution Approach 2:
The shared image processing circuitry provides universal processing capability for both imaging elements, reducing the need for duplicate processing units. The system can selectively activate different imaging elements based on functional requirements, providing adaptability without requiring separate complete camera systems for each function, thereby reducing manufacturing complexity and cost.
3Adaptability or versatility
If multiple high resolution cameras are provided, then functionality is improved, but power consumption increases
Solution Approach 1:
The patent combines multiple imaging elements into a single module with shared power-consuming components including the image processing unit and auto-focusing mechanisms. The shared circuitry processes images from both the first and second imaging elements, reducing redundant power consumption that would occur if separate processing units were dedicated to each camera. This enables versatile functionality while managing power consumption more efficiently.
Solution Approach 2:
The shared image processing circuitry serves both imaging elements, providing universal processing capability that reduces overall power consumption compared to having dedicated processing units for each camera. The system can selectively engage different imaging elements based on functional needs, avoiding continuous operation of all components and thereby reducing power consumption while maintaining adaptability.

AI summary
Approaches are described for selectively managing imaging elements on a computing device. A portable computing device can include a camera module that can manage the capture and/or processing of image data. The module can include a first imaging element attached to a first surface of a substrate and a second imaging element attached to a second surface of the substrate, the first surface being opposite the second surface. The image module can also include an image signal processor (ISP) or other dedicated imaging processing circuitry attached to or otherwise in connection with the substrate. The circuitry can be shared between the imaging elements, and can be configured to receive a selection of one of the imaging elements and process (e.g., depth pixel correction, etc.) captured image data based on the selected imaging element.
