Display Control Apparatus for Virtual Light Source Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems lack an effective method to facilitate user recognition of the subject to which an effect is being applied, particularly in changing the illumination direction of a virtual light source in image editing processes.
Innovation Solution
A display control apparatus with a change unit to adjust the application of effects on selected subjects and a control unit to distinguish the selected subject, allowing for intuitive control of virtual light source direction changes through touch and rotary operations, ensuring the subject remains recognizable during editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a first item is displayed to make the selected subject distinguishable from other subjects, then the subject recognition is improved, but the display screen becomes cluttered and less intuitive for effect adjustment
Solution Approach 1:
The patent applies the dynamics principle by making the display state of the first item dynamic - it is displayed initially to help users identify the selected subject, but automatically hidden when the user begins adjusting the effect parameters. This dynamic switching resolves the contradiction by providing subject recognition when needed and operational clarity when adjusting effects.
Solution Approach 2:
The first item is displayed in advance before effect adjustment begins, allowing users to confirm the selected subject. This preliminary display action ensures subject recognition is established before the adjustment process starts, after which the item is hidden to avoid interfering with the adjustment operation.
2Loss of information
If the first item is continuously displayed to indicate the selected subject, then subject identification is maintained, but the user's view of the image and effect adjustments is obstructed
Solution Approach 1:
The patent implements dynamic display control where the first item's visibility changes based on the operational state - it is displayed during subject selection phase but hidden during effect adjustment phase. This resolves the contradiction by maintaining subject identification only when necessary, preserving display area during the actual adjustment work.
Solution Approach 2:
The display of the first item follows a periodic pattern - displayed initially for subject confirmation, then hidden for effect adjustment, and can be restored if needed. This periodic showing and hiding resolves the contradiction between maintaining identification and preserving display area.

AI summary
A display control apparatus includes a change unit configured to change amount of application of a predetermined effect which is to be applied to a selected subject from a plurality of subjects, and a control unit configured to perform control to display a first item which makes the selected subject distinguishable from other subjects, wherein, in response to the change unit starting changing amount of application of the predetermined effect, the control unit performs control not to display the first item.
