  • PACKAGE STRUCTURE
    Publication number: 20240096781
    Abstract: A package structure including a semiconductor die, a redistribution circuit structure and an electronic device is provided. The semiconductor die is laterally encapsulated by an insulating encapsulation. The redistribution circuit structure is disposed on the semiconductor die and the insulating encapsulation. The redistribution circuit structure includes a colored dielectric layer, inter-dielectric layers and redistribution conductive layers embedded in the inter-dielectric layers. The electronic device is disposed over the colored dielectric layer and electrically connected to the redistribution circuit structure.

  • Systems and methods for depth map generation
    Patent number: 8824778
    Abstract: Various embodiments are disclosed for generating depth maps. One embodiment is a method implemented in an image processing device. The method comprises retrieving, by the image processing device, a (2D) image; and determining, by the image processing device, at least one region within the (2D) image having a high gradient characteristic relative to other regions within the (2D) image. The method further comprises identifying, by the image processing device, an out-of-focus region based on the at least one region having a high gradient characteristic; and deriving, by the image processing device, a color model according to the out-of-focus region. Based on the color model, the image processing device provides a depth map for (2D)-to-stereoscopic conversion.
