Depth information generator for generating depth information output by only processing part of received images having different views, and related depth information generating method and depth adjusting apparatus thereof

A depth information generator, comprising:

• a receiving circuit, arranged for receiving a multi-view video stream which transmits a plurality of images respectively corresponding to different views;
• a depth information generating block, coupled to the receiving circuit and arranged for generating a plurality of depth information outputs by processing the received images;
• and
• a blending circuit, coupled to the depth information generating block and arranged for generating a blended depth information output by blending at least the first depth information output and the second depth information output.

A depth adjustment apparatus, comprising:

• a depth information generator, comprising:
• a receiving circuit, arranged for receiving a multi-view video stream which transmits a plurality of images respectively corresponding to different views;
• and
• a depth information generating block, comprising:
• a first depth information generating circuit, coupled to the receiving circuit and arranged for generating a first depth information output by only processing part of the received images;
• and
• a view synthesizing block, arranged for generating adjusted images by performing a view synthesis/image rendering operation according to the images and at least one target depth information output derived from at least the first depth information output.
