Abstract:
PURPOSE: A convergence angle control device of a stereoscopic imaging device is provided to control a convergence angle by focusing on a desired object according to a visual fatigue level (VFL) value with only a simple operation within short time after taking an image with a stereoscopic camera. CONSTITUTION: A depth region obtaining part (400) generates a disparity map by using disparity information extracted from an image processing part (300) and generates a first depth map by using the disparity map. A segmentation part (450) converts the generated first depth map into a histogram and generates a second depth map by using the histogram. A VFL obtaining part (500) calculates a VFL value for each object from the second depth map. An automatic convergence angle control part (600) automatically controls a convergence angle by focusing on an object having the highest VFL value among the calculated VFL values.
