Digital Signal Processor Panoramic Image Enlargement

The patent extracts and highlights only the important subject portions from the panoramic image by detecting key points and automatically setting enlargement targets on these subjects. This allows the system to display only the relevant portions of the image rather than scrolling through the entire panoramic image, significantly reducing display time while preserving the importance of subjects through selective enlargement and highlighting.

The patent performs preliminary action by automatically detecting key points and subjects in the panoramic image before display, and pre-setting enlargement targets on these identified subjects. This preliminary subject identification and target setting enables the system to quickly navigate to and focus on important areas without requiring users to manually search through the entire image, thereby improving ease of operation while ensuring subject identification is maintained through automatic highlighting.

The patent implements self-service by enabling the panoramic image to automatically identify its own key points and subjects, and autonomously set enlargement targets without requiring complex manual control mechanisms. The image processing system performs automatic key point detection, subject identification, and target setting, which simplifies the user interface and reduces the need for complex device controls while maintaining the ability to focus on specific areas through selective enlargement based on automatically determined target spots.
