Camera Controller Lens Image Size Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cameras that allow for the attachment of multiple lens apparatuses with different image sizes require mechanical adjustments, leading to increased size and cost due to the need for frame dimension switching based on the image circle of the attached lens unit.
Innovation Solution
An image taking apparatus with an image pickup element, an image producing section, and a controller that judges the image size of the attached lens apparatus and adjusts the image producing region within the light receiving region of the image pickup element, while the lens apparatus includes a memory for storing image size information and a communicating unit to transmit this information to the camera, allowing for selective attachment and optimal image capture without mechanical size adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanical switching mechanism is provided to change frame dimensions based on the image circle of an attached lens unit, then the camera can accommodate different lens apparatuses with different image sizes, but the camera's size and cost increase
Solution Approach 1:
The patent replaces the mechanical switching mechanism with an electronic control system. The controller automatically identifies the attached lens apparatus type and electronically adjusts the image producing region on the image pickup element, eliminating the need for mechanical frame dimension switching mechanisms while maintaining compatibility with different lens apparatuses
Solution Approach 2:
The patent creates a universal camera body design that can accommodate multiple types of lens apparatuses with different image sizes through a single standardized mounting interface. The electronic control system provides multi-functionality by automatically adapting to different lens types without requiring physical modifications or additional mechanical components
2Device complexity
If the image producing region is fixed, then the camera structure is simplified, but image deterioration occurs when lenses with different image sizes are attached
Solution Approach 1:
The patent implements a dynamic image producing region that can be electronically adjusted based on the attached lens apparatus. The controller modifies the active region on the image pickup element in real-time according to the lens type, ensuring optimal image quality for each lens configuration while maintaining a fixed physical camera structure

AI summary
The present invention discloses an image taking apparatus which can control image deterioration caused by the image size of an attached lens apparatus and image generating region of an image pickup element not corresponding. The image taking apparatus has an image pickup element which photoelectrically converts an object image formed by the attached lens apparatus; an image producing section which produces recording image data to be recorded based on an output from the image pickup element; and a controller which judges an image size of the attached lens apparatus and changes an image producing region for producing the recording image data within a light receiving region of the image pickup element based on the judged image size.
