A system and method includes operations and steps for obtaining a moving endoscopic image. An optical device stream is received from an optical device by data processing hardware. The data processing hardware identify image frames of the image stream, each including a plurality of rows of pixels. The data processing hardware determines a row exposure value for each of the rows of pixels in each frame, and identifies a defective image frame having at least one overexposed row and a reference frame having a replacement row corresponding to the overexposed row. The data processing hardware modifies the defective image frame by replacing the overexposed row with the corresponding replacement row of the reference frame.

System and method to obtain a moving endoscopic image

An imaging system includes a light source for emitting first light and second light and an image sensor for capturing first image data and second image data in response to the first and second lights. Data processing hardware performs operations that include determining a first light value associated with an amount of light captured by the image sensor in response to the first light and applying a color map to each first light value to generate first light selected color values. The operations also include weighting a first light chroma value with a second light chroma value to generate weighted chroma values and combining luma values of each pixel of the second image data to the weighted chroma values. The operations also include generating RGB values based on the luma values of the second image data and the weighted chroma values and transmitting the RGB values to the display.

System for optimizing blended video streams

An enhanced fluorescence imaging system includes a light source for emitting non-visible and visible light and an image sensor for capturing non-visible and visible light image data. Data processing hardware performs operations that include determining a non-visible value associated with an amount of non-visible light captured by the image sensor and applying a color map to each non-visible value to generate non-visible light selected color values. The operations also include weighting a visible light chroma value with a non-visible chroma value to generate weighted chroma values and combining luma values of each pixel of the visible light image data to the weighted chroma values. The operations also include generating RGB values based on the luma values of the visible light image data and the weighted chroma values and transmitting the RGB values to the display.

Improved exposure control processes, devices, and systems are provided for wide angle lens imaging systems that suffer from image distortion. The exposure control uses a model of the wide angle lens distortion that estimates the weights that respective pixels of the image would have when producing an undistorted version of the image signal, and then scales pixel intensity values by the respective weights to produce weighted pixel values. The weighted pixel values are provided to an exposure control pixel counting process to produce one or more exposure feedback control signals, which control exposure features of the imaging system.
