ABSTRACT:
An imaging apparatus using multiple image signal read out lines with an improved image quality, capable of preventing the lowering of the resolution and the appearance of the ringing artifact, as well as the appearance of the false image in a form of vertical stripes, which is particularly suitable for the application in the X-ray diagnostic apparatus. The imaging apparatus is equipped with an imaging element for receiving optical image data of an imaging target and converting the received optical image data into electric signals, having a plurality of read out lines for outputting the obtained electric signals; a mixer for mixing the electric signals transmitted through the read out lines to obtain image data in an appropriately rearranged order; a digital low pass filter for digitally removing at least one specific frequency component from the image data obtained by the mixer to obtain display image data; and a display device for displaying the display image data obtained by the digital low pass filter.
