Imaging Device Dual Pipeline Live View Blackout Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices experience blackouts during still image capture due to the momentary interruption in live view image display, which disrupts the natural viewing experience.
Innovation Solution
The imaging device employs dual pipeline processing, where the imaging element outputs live view and still image data in parallel, and a control unit adjusts the output timing of still image data to avoid blackouts in live view display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the imaging element outputs frames continuously at a fixed interval, then the live view display is smooth and continuous, but blackouts occur during still image capture when the front curtain and rear curtain are moved
Solution Approach 1:
The patent segments the frame output into two independent pipelines: a first pipeline that outputs frames at regular intervals for live view display, and a second pipeline that outputs frames at variable intervals based on shutter curtain timing. This segmentation allows each pipeline to operate independently, preventing blackouts in the live view display while capturing still images.
Solution Approach 2:
The patent introduces dynamic timing control where the second pipeline adjusts frame output timing based on the actual shutter curtain movement. The control unit dynamically determines when to output frames for still image capture, allowing flexible timing that adapts to different capture scenarios without disrupting the continuous live view display.
2Manufacturing precision
If the imaging element pauses frame output during still image capture, then the still image can be captured accurately, but the live view display experiences blackouts and interruption
Solution Approach 1:
The patent divides the frame output function into two separate pipelines: one dedicated to live view display that maintains continuous output, and another dedicated to still image capture that can pause or adjust output timing. This segmentation ensures that still image capture accuracy is maintained without interrupting the live view display continuity.
Solution Approach 2:
The control unit acts as an intermediary that coordinates between the two pipelines. It receives timing information from the shutter mechanism and adjusts the second pipeline's frame output accordingly, while the first pipeline continues outputting frames uninterrupted. This intermediary coordination resolves the conflict between still image capture accuracy and live view continuity.
3Device complexity
If the imaging element uses a single pipeline for both live view and still image capture, then the device structure is simple, but blackouts occur during still image capture
Solution Approach 1:
The patent segments the single processing pipeline into two independent pipelines: a first pipeline for live view display that outputs frames at regular intervals, and a second pipeline for still image capture that outputs frames at variable intervals. This segmentation resolves the blackout issue by allowing each pipeline to operate independently without interfering with the other.
Solution Approach 2:
The patent implements partial parallel processing where the first pipeline continues operating at full capacity for live view display, while the second pipeline handles still image capture with adjusted timing. This partial parallel action allows the system to maintain live view continuity while accommodating still image capture requirements without requiring complete system redesign.
Data Source
AI summary
An imaging device includes: an imaging element configured to output a sequence of first frames at a first interval through first image capture, and output a second frame through an instruction for second image capture; a thinning unit configured to perform thinning of the sequence of first frames and outputs the thinned first frames at a second interval; and a control unit configured to control an output timing of the second frame on the basis of the first interval or the second interval and an instruction timing for the second image capture.
