This paper describes a digital real time image demosacking implementation for high definition video cameras. It comprises one buffer for three pixel rows and one interpolator based on bilinear interpolation. It has been implemented with HDL-Verilog and mapped onto Virtex-4 XC4VLX25 from Xilinx; for a clock frequency of 150 MHZ, its throughput is 72 frames(More)
In this paper a modal analysis for a proposed capacitive MEMS accelerometer sensor that can be used as inclinometer, dynamic acceleration or vibration sensor, is shown. An analysis of the effect of frequency over the displacement of the movable electrode is made. Besides, it is shown that the natural frequencies and vibration modes depend on the application(More)
This paper presents a vision chip for laser spot detection. The sensor has an architecture that comprises a 64x64 pixel array with a pixel pitch of 38.6μm x 30.8μm and fill factor of 30% and two position processors that deliver coordinate position for both axes. Under maximum speed condition, power consumption was 103mW, where maximum(More)
