An image processing device includes a multiplierfor multiplying a pixel signal P(x) by a weighting factor &#x3b1;(0&#x2266;&#x3b1;&#x2266;1), a delay elementfor delaying the pixel signal P(x) which has not been multiplied yet by the weighting factor &#x3b1;by the multiplierby one pixel, and a multiplierfor multiplying the pixel signal P(x&#x2212;1) delayed by the delay elementby a weighting factor &#x3b1;(0&#x2266;&#x3b1;&#x2266;1), the total sum of the weighting factors &#x3b1;and &#x3b1;being larger than 1 and smaller than an upper limit &#x3b1;max. An adderadds the multiplication result &#x3b1;&#xb7;P(x) of the multiplierand the multiplication result &#x3b1;&#xb7;P(x&#x2212;1) of the multiplier, and a limiterlimits the addition result P'(x) of the adderin such a way that P&#x2032;(x) falls within a maximum density value Pmax.

Image processing device and image processing program

In an communication system comprising a transmitter unit for digitally converting an input image signal and for outputting the converted image signal, and a receiver unit for entering thereinto the image signal derived from the transmitter unit and for displaying this entered image signal, the receiver unit outputs to the transmitter unit, an end signal for indicating that a display process of the image signal entered from the transmitter unit is accomplished.
