  • Exposure time determination method for image sensing operation
    Patent number: 10417476
    Abstract: An exposure time determination method for image sensing operation includes: providing a first stage exposure condition which includes a first exposure time; sensing an image according to the first stage exposure condition to generate a first histogram which has a first histogram brightness maximum, a first histogram brightness minimum, and a first histogram width; increasing or decreasing the first exposure time to a second exposure time as a second stage exposure condition, and sensing the image according to the second stage exposure condition to generate a second histogram which has a second histogram brightness maximum, a second histogram brightness minimum, and a second histogram width; comparing the first histogram width with the second histogram width to generate a comparison result, and determining a third exposure time to be a third stage exposure condition according to the comparison result; and sensing the image according to the third stage exposure condition.

  • Multi-core electronic system having a rate adjustment module for setting a minimum transmission rate that is capable for meeting the total bandwidth requirement to a shared data transmission interface
    Patent number: 8850248
    Abstract: A multi-core electronic system for accessing a data storage device includes a plurality of processors, a data transmission interface and a rate adjustment module. The processors respectively provide a bandwidth requirement, and communicate with the data storage device via the shared data transmission interface. The rate adjustment module receives the bandwidth requirements, and determines a transmission rate of the data transmission interface according to the bandwidth requirements.
