Overview:
Human eyes have a wider dynamic range than CMOS image sensors (CIS), leading to differences in how objects are perceived in images or videos. To address this, CIS and IP algorithms have been developed to express a higher range of brightness. High Dynamic Range (HDR) based on Single Exposure has limitations in recreating the Saturation Region, prompting the development of Wide Dynamic Range (WDR) using Multi Exposure images. The IP supports PWL companding mode or Linear mode to perform WDR. It analyzes the full-image histogram for global tone mapping and maximizes visible contrast in local areas for enhanced dynamic range.
