Patent EP-0844588-A3 (EP)
Inventor: TOSHIKAZU TAMURA
IPC: G06T3/40
Filed: 1997-11-24
Abstract: There is provided an image processing apparatus
constructed by an irradiating unit for irradiating a
radioactive ray to an object to be examined, a
detecting unit constructed by 2-dimensional image
pickup devices for converting a transmission image
transmitted through the object into an optical image
and picking up the optical image, a driving unit for
driving the 2-dimensional image pickup devices of the
detecting unit by an n-row In is a natural number)
interlaced scan, and an image display unit for
displaying image data obtained by the driving of the
driving unit, wherein the image display unit has a
first display mode for displaying an image every image
data obtained by the driving of the driving unit and a
second display mode for forming and displaying an image
of one frame by using the image data of a plurality of
frames obtained by the driving of the driving unit. 
     There is provided an image processing apparatus
constructed by an image pickup unit constructed by 2-dimensional
image pickup devices, a driving unit for
driving the 2-dimensional image pickup devices of the
image pickup unit by an n-row In is a natural number)
interlaced scan, and a display unit for displaying an
image signal picked up by the image pickup unit,
wherein the display unit has a first display mode for
displaying an image every image data obtained by the 
driving of the driving unit and a second display mode
for forming and displaying an image of one frame by
using the image data of a plurality of frames obtained
by the driving of the driving unit. 
     There is provided an image processing apparatus
constructed by an image pickup unit for converting a
radioactive ray transmitted through an object to be
examined into an optical image and picking up the
optical image by 2-dimensional image pickup devices,
and a display unit for displaying image data picked up
by the image pickup unit, wherein pixel data of the 2-dimensional
image pickup devices is read out by an n-row
In is a natural number) interlaced scan and the
display unit has a first display mode for displaying an
image every image data read out from the 2-dimensional
image pickup devices by the n-row interlaced scan and a
second display mode for forming and displaying an image
of one frame by using a plurality of frames from the
image data read out from the 2-dimensional image pickup
devices by the n-row interlaced scan. 
     There is provided an image processing method of
reading out and displaying image signals picked up by
radioactive ray 2-dimensional image pickup devices,
constructed by a reading step of reading out the image
signals from the image pickup devices by an n-row In is
a natural number) interlaced scan driving, a first
display step of displaying an image every image signal 
read out by the reading step, and a second display step
of forming an image signal of one frame from the image
signals of a plurality of continuous frames in the
first display step and displaying an image. 
     According to further another embodiment, there is
provided an image processing method of reading out and
displaying image signals from radioactive ray 2-dimensional
image pickup devices, constructed by a
first reading step of reading out the image pickup
devices every n rows In is a natural number), a first
display step of displaying an image every image signal
read out by the first reading step, a second reading
step of reading out the image signals from the
remaining image pickup devices in parallel with the
first display step, and a second display step of
forming and displaying one image by using the image
signals read out by the first and second reading steps.
