Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras lack intuitive color filter selection and visibility, leading to operability issues and potential erroneous photographing operations, as users struggle to grasp the effects of color filters without physical filters and clear visual cues.
Innovation Solution
A digital camera with a selecting unit that uses colored identifiers, such as circles painted over with specific colors, to represent filter options on a display, allowing users to intuitively select and confirm the chosen filter, mimicking the effect of color filters used in silver salt film cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If color filters are represented by character strings such as 'yellow filter' and 'green filter' in the menu, then the device complexity is reduced, but the ease of operation deteriorates because users can hardly intuitively grasp colors
Solution Approach 1:
The patent applies color changes by displaying colored circles (red, green, blue, yellow) in the menu to represent different color filters. This allows users to intuitively grasp the color effects without needing to read character strings, directly resolving the contradiction between menu simplicity and operational intuitiveness
2Device complexity
If a color filter is not physically employed in a digital camera, then the device complexity is reduced, but the reliability deteriorates because users may forget that a color filter has been selected, causing erroneous photographing operations
Solution Approach 1:
The patent implements feedback by displaying the selected color filter information (colored circles) on the LCD screen during photographing operations. This visual feedback continuously reminds users of the selected filter effect, preventing erroneous operations while maintaining the simplicity of digital filter implementation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user operability by allowing intuitive filter selection and confirmation, reducing the likelihood of errors and improving the efficiency of monochromatic photographing operations by visually representing the selected filter effect.
Implementation Method 1
an imaging unit that photoelectrically converts entered light to output a color image
Data Source
AI summary
A digital camera includes: an imaging unit that photoelectrically converts light to output a color image; a selecting unit that selects any one identifier from identifiers which are colored in different colors from each other; and a black/white image producing unit that produces a black/white image by weighting gradation values of respective colors for each of pixels of the output color image and adding the weighted gradation values to each other. When the light entered to the imaging unit is entered to a color filter having a color equal to a color of the selected identifier, a correlation between a light amount of light having a wavelength which penetrates the color filer and a light amount of the entered light becomes stronger than a correlation between a light amount of light having a wavelength which is absorbed by the color filter and the light amount of the entered light.
