Camera system and method for encoding two video image frames captured by a respective one of two image sensors

A non-transitory computer-readable storage medium having stored thereon instructions for implementing a method when executed in a device having at least one processor and at least one encoder, the method for encoding two video image frames captured by a respective one of two image sensors, wherein each of the two video image frames depicts a respective portion of a scene, the method comprising:

• identifying a respective overlapping area in each of the two video image frames, which overlapping areas both depict a same sub-portion of the scene;
• selecting a video image frame of the two video image frames;
• setting compression values for the two image frames, wherein respective compression values are set for pixel blocks in the selected video image frame based on a respective interest level associated with the pixel blocks in the selected video image frame, and wherein respective compression values for pixel blocks in the overlapping area in the selected video image frame are selectively set higher than respective compression values that would have been set for the pixel blocks in the overlapping area based on the respective interest level associated with the pixel blocks in the overlapping area;
• and
• encoding the two video image frames.

An image processing device for encoding two video image frames captured by a respective one of two image sensors, wherein each of the two video image frames depicts a respective portion of a scene, the image processing device comprising:

• circuitry configured to execute:
• an identifying function configured to identify a respective overlapping area in each of the two video image frames, which overlapping areas depict a same sub-portion of the scene,
• a selecting function configured to select a video image frame of the two video image frames, and
• a setting function configured to set compression values for the two image frames, wherein respective compression values are set for pixel blocks in the selected video image frame based on a respective interest level associated with the pixel blocks in the overlapping area, and wherein respective compression values for pixel blocks in the overlapping area in the selected video image frame are selectively set higher than respective compression values that would have been set for the pixel blocks in the overlapping area based on the respective interest level associated with the pixel blocks in the overlapping area;
• and
• at least one encoder for encoding the two video image frames.
