Image Pickup Apparatus Single Encoder Still-Moving Image Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses require multiple encoders and large-capacity memory to record moving images before and after still images, leading to increased size and cost, and may miss shooting opportunities if not enough resources are available.
Innovation Solution
An image pickup apparatus that records moving images before or after still images using a single encoder and memory, allowing for multiple still images to be shot within a predetermined time period without the need for multiple encoders and large-capacity memory, by controlling the recording of moving images based on received shooting instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple moving image encoders and large-capacity memory are provided to record overlapping moving images in parallel, then the ability to record multiple still images within a predetermined time period is improved, but the size and cost of the image pickup apparatus increase
Solution Approach 1:
The patent merges multiple moving image encoding processes into a single encoder by sequentially processing moving images corresponding to different still images. Instead of using multiple encoders to process overlapping time periods in parallel, the system uses one encoder to sequentially encode moving images from different time periods, thereby reducing hardware complexity while maintaining the ability to capture multiple still images within a predetermined time period.
Solution Approach 2:
The system performs preliminary recording of moving images in a buffer memory before encoding. By temporarily storing moving image data from multiple time periods in the buffer memory and then sequentially encoding them, the system prepares the data in advance for processing, allowing the single encoder to handle multiple still images without missing any shooting opportunities.
2Device complexity
If a single encoder is used to record moving images, then the size and cost of the image pickup apparatus are reduced, but the ability to record multiple still images within a predetermined time period may be compromised
Solution Approach 1:
The system performs preliminary recording of moving images in the buffer memory before encoding. By temporarily storing moving image data from multiple time periods in advance, the single encoder can sequentially process and encode these pre-recorded moving images without missing any shooting opportunities, thus maintaining high productivity with reduced hardware complexity.
Solution Approach 2:
The system dynamically manages the buffer memory to store moving image data from different time periods corresponding to multiple still images. By flexibly allocating buffer memory resources and sequentially feeding data to the single encoder, the system adapts to multiple shooting scenarios within a predetermined time period, maintaining productivity while using minimal hardware.

AI summary
An image pickup apparatus which is capable of shooting a plurality of still images as instructed within a predetermined time period without a plurality of moving image encoders and a large-capacity memory. When a second still image shooting instruction has been received within a predetermined time period since a first still image shooting instruction was received, a moving image picked up before lapse of the predetermined time period after the second still image shooting instruction from a moving image shooting starting timing corresponding to the first still image shooting instruction is recorded as a sequence of moving images.
