摘要:
A dynamic-image displaying workstation provided with a display device for displaying an image, a video signal processing circuit for outputting dynamic-image data representing a dynamic image corresponding to a video signal, a first dual port memory for receiving and storing the dynamic-image data outputted from the video signal processing circuit, a second dual port memory for storing data representing pixels of an image to be displayed by the display device, and a third dual port memory for storing data representing a window area. The window area is an area of a window, to which the dynamic-image belongs, and is not covered by any other windows. The workstation is further provided with a fourth dual port memory for storing data representing a dynamic-image display effective area corresponding to the dynamic image represented by the dynamic-image stored in the first dual port memory, a data selector for receiving data read from the first dual port memory at a first input terminal thereof, and data read from the second dual port memory at a second input terminal thereof, for selecting one of the third and fourth dual port memories and receiving data read from the selected dual port memory at a third input terminal thereof, for selecting the data received at the first input terminal thereof if the data read from the third dual port memory is the data representing the window area, and the data read from the third dual port memory is the data representing the dynamic-image display effective area, for selecting the data received at the second input terminal thereof and for outputting a signal representing the selected data to the display device.

Pixel data is selected from among first and second dynamic-image memories (DI1, DI2) and a static-memory (SI). In the invention, (a) first and second window area memories (WA1, WA2) for designating shapes and sizes of windows to which video dynamic-images are assigned respectively, (b) first and second dynamic-image area memories (DA1, DA2) for designating memory locations of data stored in both the dynamic-image memories, and (c) a priority control register for designating which video dynamic-image should be displayed in front when video dynamic-images overlap with each other are provided, whereby display for every pixel is executed according to a logical AND value of read-out data from WA1 and read-out data from DA1, a logical AND value of read-out data from WA2 and read-out data from DA2, and read-out data from the priority control register. Thus two video dynamicimages assigned to their respective windows are simultaneously displayed while subjecting them to overlap control, and special techniques including auto-zooming can be accomplished in real time.

A signal detecting apparatus is to obtain hysteresis characteristic at a constant ratio regardless of signal amplitude fluctuations by supplying the threshold level adjusting signal corresponding to the input signal amplitude to the comparison circuit. The threshold value setting signal and the hysteresis adjusting signal is supplied to a comparison circuit through an amplifier and a hysteresis adjusting means having the identical characteristic with the peak hold circuit to set a threshold value and a hysteresis range. Therefore even in the case where the operating characteristic of the amplifier and the peak hold circuit for detecting the peak level of signal amplitude fluctuate, the threshold value and the hysteresis range fluctuation corresponding to the fluctuation. As a result, there can not need the adjustment for resetting the operating characteristic, the threshold value and the hysteresis range in each circuit and thus the time and labor required for adjustment can be further saved.
