Camera Image Readout Switching with Preloaded Mode Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image readout mode switching methods in electronic devices experience delays and fluency issues due to the need to download extensive configuration parameters when switching between modes, leading to non-fluent picture display and freezing.
Innovation Solution
An image readout mode switching method that loads configuration parameters for multiple modes upon entering a camera mode, determines a target mode based on scene analysis, and uses a reduced set of register sequences for mode switching, minimizing delays and maintaining fluent picture display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device downloads the configuration parameter of the image readout mode when switching modes, then the image readout mode can be switched, but the switching delay increases and picture fluency deteriorates
Solution Approach 1:
The patent pre-loads configuration parameters for multiple image readout modes (first mode and second mode) when entering the camera mode, so that when mode switching is needed, the parameters are already available in memory. This eliminates the download delay during actual mode switching, resolving the contradiction between mode adaptability and switching speed.
2Adaptability or versatility
If the electronic device loads the configuration parameter for image readout mode switching, then the mode can be switched, but the loading time becomes excessively long causing freezing
Solution Approach 1:
The system performs the configuration parameter loading action in advance when the camera mode is entered, rather than when switching is triggered. This preliminary loading ensures that multiple modes are ready beforehand, preventing loading delays from affecting picture display fluency during mode transitions.
Solution Approach 2:
The patent merges the configuration parameter loading process with the camera mode entry process. By combining these two operations, the system loads parameters for multiple image readout modes as part of the initial camera setup, eliminating separate loading operations that would cause freezing during mode switching.
3Loss of time
If the electronic device uses a reduced set of register sequences for mode switching, then switching speed improves, but the completeness of configuration may be compromised
Solution Approach 1:
The patent pre-loads the complete configuration parameters for multiple image readout modes when entering the camera mode. This ensures that even though a reduced set of register sequences is used during switching, the full configuration data is already available in memory, maintaining completeness while achieving fast switching.

AI summary
An image readout mode switching method and a related device. According to the method, an electronic device collects an image based on a first image readout mode in a first camera mode, switches, in a case that a switching condition for switching from the first image readout mode to a second image readout mode is satisfied, a configuration parameter of a currently applied image readout mode from a configuration parameter of the first image readout mode to a configuration parameter of the second image readout mode based on a corresponding mode switching configuration parameter, and acquire an image based on the second image readout mode in the first camera mode. The configuration parameter of the second image readout mode is a configuration parameter that is preloaded before switching to the second image readout mode is determined.
