  • Microscopic image detecting instrument and automatic focusing method therefor

    A microscopic image detecting instrument includes a microscope, a photographing device, a driver, a mark having a predetermined distance from an object, and a controller coupled to the photographing device and the driver. The microscope includes an object stage for holding the object and an objective lens for focusing on and magnifying the object. The photographing device is set above the objective lens to photograph an image presented by the objective lens. The controller controls the driver to move at least one of the object stage and the objective lens to an actual focusing position, according to an actual focal length to the object. The actual focal length to the object is calculated by the controller according to a comparison between an optical definition of a mark image taken as a preliminary target of focus against a predetermined definition calibration curve and the distance between the mark and the object.

  • Architecture and control of reed-solomon error-correction decoding

    Systems and methods are provided for implementing various aspects of a Reed-Solomon (RS) error-correction system. A detector can provide a decision-codeword from a channel and can also provide soft-information for the decision-codeword. If the decision-codeword corresponds to an inner code and an RS code is the outer code, a soft-information map can process the soft-information for the decision-codeword to produce soft-information for a RS decision-codeword. A RS decoder can employ the Berlekamp-Massey algorithm (BMA), list decoding, and a Chien search, and can include a pipelined architecture. A threshold-based control circuit can be used to predict whether list decoding will be needed and can suspend the list decoding operation if it predicts that list decoding is not needed.

  • Method for semantics based trick mode play in video system

    Trick mode play for controlling video content playback can be realized using a semantic based criterion in order to achieve a more uniform playback experience for the viewer, when that viewer wishes to observe the video content presented according to a selected semantic. In one embodiment of the method, semantics associated with shorter time intervals in the video content are replayed in trick mode play proportionally slower than semantics associated with longer time intervals, wherein the proportionally is determined, at least in part, to the time interval associated with each semantic. In various embodiments, semantics can include scenes, audio, metadata, tags, and the like. The semantics based trick mode play approach allows for a more uniform viewing experience, on a time duration basis, from one semantic to the next.
