Abstract

Stereoscopic image capture is provided. A blur value expected for multiple pixels in left and right images is predicted. The blur value is predicted based on designated capture settings. A disparity value expected for multiple pixels in the left and right images is predicted. The disparity value is predicted based on the designated capture settings. Stressed pixels are identified by comparing the predicted disparity value to a lower bound of disparity value determined from the predicted blur value using a predetermined model. A pixel with predicted disparity value less than the lower bound is identified as a stressed pixel. The predicted disparity is adjusted by modifying the designated capture settings to reduce the number of stressed pixels, or an alert to the presence of stressed pixels is given to the user.

First claim

What is claimed is:

1. A method for stereoscopic image capture, comprising:
predicting a blur value respectively for each of multiple pixels in left and right images, wherein the blur value is predicted based on designated capture settings;
predicting a disparity value respectively for each of multiple pixels in the left and right images, wherein the disparity value is predicted based on the designated capture settings;
determining a lower bound of disparity value respectively…
