Camera Lens Focus Scale Readability via Segmented Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting and displaying image sharpness (focus) on camera lenses face challenges with limited space on marking disks and remote controls, leading to poor visibility and confusion when adjusting settings, especially with multiple markings close together.
Innovation Solution
The method involves varying the scale of an analog adjustable scale to ensure optimal readability by displaying setting values on the edge of the scale, using markers outside the display window, and enhancing visibility with different symbols, colors, and alphanumeric characters, along with a table for marking order, to maintain user orientation and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple setting values are marked on a limited space marking disk or remote control display, then more setting options are available, but visibility and recognizability of individual markings deteriorate
Solution Approach 1:
The patent divides the display into multiple segments: a main display window showing current setting values and a separate marking table displaying all marked values. This segmentation allows multiple markings to be visible simultaneously without crowding the main display area, resolving the contradiction between providing multiple setting options and maintaining visibility of individual markings.
Solution Approach 2:
The patent transitions from a one-dimensional linear display of setting values to a two-dimensional table structure with rows and columns. The marking table displays marked values in a grid format where one dimension represents the marking position and the other represents the setting value range, allowing comprehensive display of multiple markings without spatial conflict.
2Area of stationary object
If the scale range is expanded to show more setting values, then more of the adjustment range is visible, but the readability of individual setting values deteriorates
Solution Approach 1:
The patent segments the display functionality between a main window that shows a limited, high-resolution view of the current setting range, and a marking table that provides an overview of all marked values across the full adjustment range. This segmentation allows the main display to maintain high readability while the marking table compensates by showing the broader range.
Solution Approach 2:
The patent creates a simplified copy of the setting values in the marking table, where marked values are represented as discrete entries rather than continuous scale markings. This copying approach allows the full range of marked values to be displayed without requiring the same visual precision as the main setting display, thus resolving the contradiction between display range and readability.
3Area of stationary object
If the display window size is limited, then the operating unit remains compact and portable, but the number of visible setting values is reduced
Solution Approach 1:
The patent segments the information display into two parts: a compact main window for current setting values and a marking table for additional marked values. This segmentation allows the operating unit to remain compact while still providing access to information about multiple setting values through the marking table, which can be scrolled or expanded as needed.
Solution Approach 2:
The patent implements a dynamic display system where the marking table can be adjusted to show different ranges of marked values, and where additional markings can be added or removed based on user needs. This dynamic capability allows the limited display area to adaptively show the most relevant information while maintaining compact dimensions.

AI summary
The invention relates to a method for adjusting and for displaying the adjustment of a camera lens, particularly for adjusting the focus of a camera lens for analog or digital motion picture cameras, comprising a scale (7) that can moved relative to the display of a present adjustment value and that is coupled with an adjustment device (50, 61 - 64). Adjustment values (71) are depicted numerically and/or as graphical symbols on the scale, and a scale range of the scale bordering on the present adjustment value is located in a display window (6). At least one adjustment value (71) is highlighted by a marking (81 - 85), and marking (81, 82, 84) located outside the display window (6) is displayed at the edge of the scale (7) at which it would be located on a virtually expanded scale (7).
