Abstract
An emphasis convertercompares the image data of the current vertical period with the image data of the previous vertical period and controls the input image data to a liquid crystal display panelbased on the emphasis conversion parameters stored in tables of ROMstoso as to achieve accelerated drive. A microcomputeris able to realize stable control of selecting emphasis conversion parameters by adding hysteresis to the detected temperature from a thermistoreven when the detected temperature fluctuates up and down crossing the temperature threshold.
