  • Image processing device, image signal processing chip, and ISP chain configuring method
    Patent number: 8928767
    Abstract: An image processing device and an ISP chain constructing method are provided which can arbitrarily reconstruct an ISP chain structure. The image processing device is connected to an image sensor, performs a signal process and includes: N (where N is a natural number of equal to or greater than 2) ISP (Image Signal Processing) functional modules that each perform a predetermined image signal process on one, which is determined by an input selection signal, of data output from the image sensor and the other ISP functional modules; and an output module that outputs one, which is determined by an output selection signal, of output data output from the N ISP functional modules as final output data. Accordingly, it is possible to reconstruct an ISP chain even after the ISP chain is embodied as a chip, thereby providing image processing functions optimized for various product applications.
