  • Image processing device with expander minimizing memory requirements for obtaining multiple sub window image data
    Patent number: 6052154
    Abstract: An image processing device for displaying a sub window of second video data on one part of a main screen by switching first video data for the entire screen and the second video data for the sub window includes an analog-to-digital converter for digitizing the second video data and a data sampling circuit for sampling and compressing the digitized video data at a subsampling frequency. The device further includes a memory for reading out and storing the compressed data sampled in the data sampling circuit; a first switching circuit including a data expansion circuit for generating video data for the sub window by expanding the image data read from the memory; a digital-to-analog converter for converting the image data expanded in the data expansion circuit to obtain analog data; and a second switching circuit for switching the video data for a sub window output from the digital-to-analog converter to insert the video data in the sub window into the first video data.
