Image depth calculating device and method

An image depth calculating device comprising:

• at least one storage configured to store a plurality of modules, the plurality of modules being a collection of instructions of an application operable in the device;
• at least one processor configured to execute the plurality of modules, the modules comprising:
• a receiving module receiving a first frame information set that corresponds to a first frame time of a binocular video, the first frame information set comprising first view angle frame information and second view angle frame information;
• a first establishing module establishing a first rhombic area that centers on a first pixel of a first view angle frame;
• a first pixel calculating module calculating a first total pixel value of the first rhombic area;
• a second establishing module establishing a pixel area in a second view angle frame according to a predetermined depth level and the first pixel, and further establishing a plurality of second rhombic areas that center on each second pixel of the pixel area;
• a second pixel calculating module calculating a second total pixel value of each of the plurality of second rhombic areas;
• and
• a depth calculating module comparing the first total pixel value with each of the second total pixel values and calculating first frame depth information according to a result of the comparison;
• wherein the first rhombic area and each of the second rhombic areas have the same size and shape.
