Electronic Camera Filter for Dynamic Optical Control

Solution Overview

Problem

Manual interchange of camera filters during movie productions is inefficient, requiring time and increasing production costs, especially when cameras are in hard-to-reach locations like high cranes.

Innovation Solution

An electronic filter system with a display that can dynamically control image filtering on a pixel-by-pixel basis using electronic technology such as organic light-emitting diodes (OLEDs) or liquid crystals, allowing remote and rapid adjustment of optical effects without physical swapping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual filter interchange is used, then filter effects can be changed, but time consumption and production cost increase

Engineering Contradiction:

Improvefilter effect variationVSAvoidtime to swap filters

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical system of manually swapping physical filters with an electronic display system controlled by a controller. The electronic display dynamically adjusts filtering effects through electrical signals, eliminating the need for physical filter interchange while maintaining the ability to vary filter effects during shots.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements dynamic filter control where the electronic display can continuously and rapidly adjust filtering parameters during a shot. This allows real-time variation of filter effects without stopping production or manually intervening, making the system adaptable and responsive to changing scene requirements.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If manual filter interchange is used, then filter effects can be changed, but production cost increases

Engineering Contradiction:

Improvefilter effect variationVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent replaces the mechanical system of manually swapping physical filters with an electronic display system controlled by a controller. The electronic display dynamically adjusts filtering effects through electrical signals, eliminating the need for physical filter interchange while maintaining the ability to vary filter effects during shots.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electronic display system serves multiple functions: it acts as both the display element and the filter control mechanism. A single device can produce multiple different filter effects through electronic control, replacing the need for multiple physical filters and the manual labor required to swap them, thereby reducing production costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If manual filter interchange is used, then filter can be swapped, but operation complexity increases for high crane locations

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical system of manually swapping physical filters with an electronic display system controlled by a controller. The electronic display dynamically adjusts filtering effects through electrical signals, eliminating the need for physical filter interchange while maintaining the ability to vary filter effects during shots.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electronic display system is self-controlled through electrical signals from a controller, eliminating the need for manual physical intervention. The system can adjust filter effects automatically or through remote electronic control, making operation simple and accessible even when the camera is in hard-to-reach locations like high cranes.
