Camera Controller for Simultaneous Movie and Still Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses fail to capture still images when the shutter button is operated while the mode switch is set for movie recording, resulting in failed still image capture.
Innovation Solution
The apparatus includes an image pickup device, generation circuits for movie and still image data, a recording circuit, and a controller that allows for the generation and recording of still image data from movie data, even if initially recorded in an incorrect mode, with associated data storage and display mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mode switch is set for movie recording, then movie recording can be performed, but still image capture becomes unavailable when the shutter button is operated
Solution Approach 1:
The controller enables the still image generation circuit to generate still image data from the movie data obtained by the image pickup device, even when the mode switch is set for movie recording. This allows the recording apparatus to perform both movie recording and still image capture functions simultaneously or alternatively, making the system more versatile and reliable regardless of the mode switch setting.
2Ease of operation
If a mode switch is used to separate movie and still image modes, then recording functions can be controlled, but incorrect operation may cause failure to capture still images
Solution Approach 1:
The controller continuously monitors the operation state and mode switch setting, and automatically adjusts the operation of the still image generation circuit accordingly. When the mode switch is set for movie recording, the controller enables still image generation from movie data, providing feedback-based adaptation that prevents capture failure due to incorrect operation.
Solution Approach 2:
The controller prepares the still image generation circuit to operate in advance by enabling it to process movie data even when movie recording mode is selected. This preliminary configuration ensures that still image capture is already ready and can execute successfully when the shutter button is pressed, preventing operational failures.
3Adaptability or versatility
If still image data is generated from movie data, then still images can be obtained during movie recording, but data processing complexity increases
Solution Approach 1:
The still image generation circuit utilizes the movie data already obtained by the image pickup device during movie recording to generate still image data. By merging the use of the same input signal for both movie and still image generation, the system achieves dual recording capability without requiring separate hardware paths, thereby limiting the increase in processing complexity.

Function Achieved in This Case
Enables the capture and recording of still images during movie recording operations, allowing for their retrieval and display, even when the initial operation was intended for movie recording.
Implementation Method 1
an image pickup device configured to convert an optical image of an object into an image signal
Data Source
AI summary
Still image data generated in response to an instruction for starting the recording of movie data is recorded in such a manner as to be associated with the movie data, and information indicating that the still image data associated with the movie data has been recorded is displayed in response to an instruction for predetermined processing on the movie data.
