— In this report, we propose a bit-depth scalable coding system based on the integer wavelet transform. Encoder of the system outputs two layered bit-streams. Decoding the base layer, upper part of the bit planes of each pixel values of an input image signal are displayed. Adding the enhancement layer, all the bit planes are reconstructed without any loss.(More)
We have developed an active matrix-addressed magneto-optical spatial light modulator driven by spin-transfer switching (spin-SLM) which has a 100 × 100 array pixel layout with a 2 µm pixel pitch. It has pixel-selection-transistors and logic circuits which convert serial data into parallel data to reduce input terminals. We have confirmed successful(More)
Global Lightning and sprIte MeasurementS (GLIMS) mission is now ongoing on Exposed Facility of Japanese Experiment Module (JEM-EF) of the International Space Station (ISS). This paper focuses on an electromagnetic (EM) payload of JEM-GLIMS mission, very high frequency (VHF) broad-band digital InTerFerometer (VITF). JEM-GLIMS mission is designed to conduct(More)
