Endoscope Image Generation for Bright Still Images With Tip Heat Control

The patent applies parameter changes by capturing images at multiple different light intensity levels (first light intensity and second light intensity) and then synthesizing the results through image processing. This allows the system to achieve bright images without actually using high light intensity during capture, thereby preventing temperature increase while improving brightness through computational methods.

The patent performs preliminary actions by capturing images at both low light intensity (for temperature control) and high light intensity (for brightness reference) before final image generation. The system uses the high light intensity image as a reference to guide the synthesis process, allowing the final output to achieve brightness comparable to high-intensity images while using only low-intensity capture data, thus preventing temperature increase.

The patent uses a copy approach by capturing a reference image at high light intensity and using it as a template for synthesizing the final image. Instead of applying aggressive signal processing to a single low-quality capture, the system combines the low-light capture with the high-light reference image, effectively copying the brightness characteristics from the reference while maintaining the quality of the actual capture, thereby reducing noise.

The patent applies dynamics by adaptively selecting capture parameters based on the imaging mode (still image or moving image). For still images, the system captures at multiple light intensities and synthesizes the result, allowing high brightness without high temperature. For moving images, the system uses standard single-capture mode. This dynamic adaptation resolves the contradiction by applying the complex multi-capture method only when necessary for still image quality.
