Dynamic Tally Signal Frame Width for Display Overlap Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image capturing systems, the visibility of image capture information is compromised when the display of a tally signal and OSD information overlap, leading to reduced clarity of both the tally signal indication and the image capture details.
Innovation Solution
A display control apparatus that receives a tally signal and controls the display of a captured image on a screen, ensuring that a display item indicating the tally signal is shown along the edge with a varying width based on the display mode, thereby maintaining visibility of both the tally signal and image capture information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a band-shaped frame is displayed in the peripheral portion to indicate tally signal reception, then the visibility of the tally signal is improved, but the visibility of image capture information deteriorates due to overlap with OSD display
Solution Approach 1:
The width of the band-shaped frame is dynamically adjusted based on the display mode. In full screen display mode, the frame width is set to a first width, while in picture-in-picture display mode, the frame width is set to a second width that is narrower than the first width. This dynamic adjustment prevents overlap with OSD display in different display scenarios while maintaining visibility of the tally signal.
2Length of moving object
If the frame width is increased to improve tally signal visibility, then the tally signal becomes more prominent, but the overlap with OSD information increases causing information loss
Solution Approach 1:
The frame width is made dynamic rather than fixed. The control unit switches between a first width (wider) for full screen display mode and a second width (narrower) for picture-in-picture display mode. This allows the frame to be prominent when needed while avoiding overlap that would cause information loss in different display contexts.
Solution Approach 2:
The physical parameter of frame width is changed based on display mode conditions. By adjusting this parameter according to whether the display is in full screen or picture-in-picture mode, the system optimizes both tally signal visibility and prevention of information overlap.

AI summary
A display control apparatus including a display unit, comprising a receiving unit configured to receive a tally signal from an external apparatus, and a display control unit configured to perform control so that a captured image captured by an imaging unit is displayed on a display unit, wherein the display control unit performs control, in accordance with the receiving unit having received the tally signal, so that a display item that indicates that the tally signal has been received is displayed along the edge of the display unit, and performs control, in accordance with a display mode of the captured image, so that the display item is displayed with a different width.
