Issue
HDR, or High Dynamic Range, is a digital photography technique that improves the resolution of images by capturing a wider range of brightness and luminosity. This allows for a more realistic and visually appealing representation of the scene, similar to how the human eye perceives objects. However, both cameras and human eyes have limitations, especially in low-light or nighttime conditions when objects may not be well-illuminated. In such situations, traditional cameras have two options: increase brightness but introduce noise, or decrease brightness, resulting in poorly illuminated objects. This presents a challenge, particularly for video recording, as cameras need to be prepared to capture low-light moments in advance. In summary, low-light conditions can limit a camera's ability to capture light effectively. However, with careful adjustments, these limitations can be mitigated.
Proposing Idea
The project proposes using the biomimicry method to address the low-light issue by studying the gecko, a nocturnal animal with exceptional vision in low-light conditions. The focus of the research will be the helmet gecko, which has 350 times higher cone vision than humans, allowing it to perceive color in low-light conditions. The project aims to uncover the techniques employed by the helmet gecko and use them to develop a process for producing HDR (High Dynamic Range) images in low-light conditions. The expected outcome is a procedure for transforming raw images into HDR images, simulating the visual perspective of the gecko's eyes.
Steps and Procedure
Human = 6-7mm = f.2.1 ( Hecht, Eugene (1987). Optics (2nd ed.). Addison Wesley. ISBN 0-201-11609-X. Sect. 5.7.1)
Human eye iso low light = 800 [https://www.bhphotovideo.com/c/find/newsLetter/The-Photographic-Eye.jsp#:~:text=That said%2C the answer to,an ISO of about 800.](https://www.bhphotovideo.com/c/find/newsLetter/The-Photographic-Eye.jsp#:~:text=That said%2C the answer to,an ISO of about 800.)
Gecko = 10mm2 = 10 mm = x?
X= f.3.5
Gecko = f.3.5 = 0.0001cd/m2
Iso
^350
Test: human = f2.1 iso 800 & max
Gecko f3.5 iso1333.33 & max
