Image Capturing Device Wide-Angle to Narrow-Angle Projection

The patent segments the wide-angle video image into multiple narrow-angle video images. Each narrow-angle image covers a specific region of the original wide-angle view. By dividing the content, the system can selectively process and transmit only the necessary portions at high definition, reducing overall data size while maintaining quality where needed.

The patent applies different quality levels to different regions of the image. The central region of interest is transmitted at high definition, while peripheral regions are transmitted at lower definition or omitted entirely. This local quality approach ensures that bandwidth is consumed only where high image quality is necessary, resolving the contradiction between overall quality and data size.

The patent segments the wide-angle image into a low-definition base layer and high-definition overlay layers. The base layer provides overall context at reduced data size, while separate high-definition segments are transmitted for specific regions of interest, ensuring both data efficiency and quality where needed.

The patent merges low-definition wide-angle image data with high-definition narrow-angle image data. The high-definition segments are superimposed on the low-definition base image, creating a composite output that achieves both small data transmission size and high image quality in critical areas simultaneously.

The patent performs preliminary processing to identify regions of interest within the wide-angle video feed. By pre-determining which areas require high definition treatment, the system avoids complex real-time processing of the entire image, reducing computational complexity while maintaining quality where needed.

The patent creates simplified copies or representations of the high-definition regions that can be efficiently transmitted and overlaid. Instead of processing and transmitting multiple full-resolution video streams, the system uses compressed representations that reduce processing complexity while preserving essential quality characteristics.

The patent applies different resolution levels to different parts of the image. Critical regions are maintained at high resolution with fine detail, while non-critical regions are downsampled to lower resolution. This selective quality approach minimizes overall data size while preserving image definition where it matters most.

The patent transitions from a uniform two-dimensional resolution approach to a multi-layered structure where high-definition and low-definition components coexist. By adding the dimensional aspect of quality layering, the system achieves both small data size and high definition in critical areas simultaneously.
