Solution Overview

Problem

Conventional lens interchangeable type cameras do not enable users to confirm the current tilt-shift amount during tilt-shift imaging.

Innovation Solution

A lens apparatus with an imaging optical system and a transmitting unit that allows for the display of tilt-shift information on an image pickup apparatus display unit, enabling users to confirm the tilt-shift amount.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If conventional lens interchangeable type cameras adjust tilt-shift amount, then imaging capability is improved, but user cannot confirm current tilt-shift amount

Engineering Contradiction:
Improvetilt-shift amount informationVSAvoiduser operation
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism by displaying the current tilt-shift amount on the camera's display unit. The lens apparatus transmits tilt-shift amount information to the image pickup apparatus, which then presents this information to the user through the display screen. This allows users to visually confirm the current settings and make informed adjustments during tilt-shift imaging operations.

Inventive Principle:
Principle #23Feedback

2Device complexity

If lens apparatus structure is simplified, then device complexity is reduced, but functionality to transmit tilt-shift information is limited

Engineering Contradiction:
Improvelens apparatus structureVSAvoidtilt-shift amount information transmission
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The lens apparatus utilizes the existing communication interface between the lens and image pickup apparatus for multiple purposes: controlling optical members, detecting tilt-shift amounts, and transmitting this information to the display unit. By leveraging the universal communication capability already present in the system, the patent avoids adding separate dedicated hardware for information transmission, thus maintaining structural simplicity while achieving comprehensive functionality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A lens apparatus attachable to and detachable from an image pickup apparatus includes an imaging optical system that includes at least one optical member configured to move so as to change at least one of a tilt effect of tilting a focal plane relative to an imaging plane of an image sensor included in the image pickup apparatus and a shift effect of moving an imaging range, and a transmitting unit configured to transmit information about a movable range of the at least one optical member to the image pickup apparatus.
