Abstract

The image displaying apparatus includes: an image acquiring unit configured to acquire an object image to be displayed; a determining unit configured to determine whether the object image to be displayed is a predetermined display type, a reference value of which is allocated to a particular pixel value; a setting unit configured to set the WL and the WW when the object image to be displayed is displayed and fix the WL to a predetermined value when the determining unit determines that the object image to be displayed is a predetermined display type; and an image converting unit configured to convert the object image to be displayed so that the object image to be displayed is displayed at the WL fixed to the predetermined value or the set WL and with the set WW.

First claim

What is claimed is:

1 . An image displaying apparatus comprising:
an image acquiring unit configured to acquire an object image to be displayed; a determining unit configured to determine whether the object image to be displayed is a predetermined display type, a reference value of which is allocated to a particular pixel value; a setting unit configured to set a window level and a window width for displaying the object image to be displayed and fix the window level to a predetermined value when the determining unit determines that the object image to be displayed is the predetermined display type; and an image converting unit configured to convert the object image to be displayed so that the object image to be displayed is displayed with the window level fixed to the predetermined value or the set window level and with the set window width.

2 . The image displaying apparatus according to claim 1 , further comprising a display control unit configured to cause a display unit to display the converted object image to be displayed.

3 . The image displaying apparatus according to claim 1 , wherein the setting unit has a mode in which the window level and the window width can be both set through a single operation and fixes the window level to the predetermined value when the object image to be displayed is determined to be of the predetermined display type in the mode.

4 . The image displaying apparatus according to claim 3 , wherein the setting unit fixes, in the mode, the window level to the predetermined value by providing a dead zone of a predetermined range to an input value for setting the window level.

5 . The image displaying apparatus according to claim 1 , wherein the setting unit receives change of the window width while the window level is fixed.

6 . The image displaying apparatus according to claim 1 , wherein the setting unit automatically adjusts the window width based on a distribution of pixel values of the object image to be displayed while the window level is fixed.

7 . The image displaying apparatus according to claim 1 , wherein the reference value is set as a window level.

8 . The image displaying apparatus according to claim 1 , wherein the predetermined display type is a display type of an image obtained from a difference or change amount between a plurality of images.

9 . The image displaying apparatus according to claim 8 , wherein the predetermined display type is a difference image generated by converting each difference between the plurality of images into a pixel value.

10 . The image displaying apparatus according to claim 8 , wherein the predetermined display type is a Jacobian map generated from a scaling ratio of deformation between the plurality of images.

11 . The image displaying apparatus according to claim 8 , wherein the predetermined display type is a displacement field image generated from a movement amount of each pixel between the plurality of images.

12 . The image displaying apparatus according to claim 1 , wherein the determining unit determines whether the object image to be displayed is the predetermined display type based on information added to the object image to be displayed.

13 . The image displaying apparatus according to claim 1 , wherein the determining unit determines whether the object image to be displayed is the predetermined display type based on a distribution of pixel values of the object image to be displayed.

14 . The image displaying apparatus according to claim 1 , wherein the determining unit determines whether the object image to be displayed is the predetermined display type based on a display type specified by a user.

15 . The image displaying apparatus according to claim 1 , wherein the image converting unit non-linearly converts each pixel value of the object image to be displayed into a display value.

16 . An image displaying apparatus comprising:
an image acquiring unit configured to acquire an object image to be displayed; a display control unit configured to control a display unit to display the object image to be displayed with a predetermined window level and a predetermined window width; and a setting unit having a mode in which the predetermined window level and the predetermined window width are both reset through a single operation, and configured to reset the predetermined window level and the predetermined window width; and wherein, when the object image to be displayed is a display type of an image, a reference value of which is allocated a particular pixel value, the setting unit includes a control unit configured to limit setting of the window level in the mode.

17 . The image displaying apparatus according to claim 16 , wherein the control unit limits the setting by providing a dead zone of a predetermined range to an input value for setting the window level.

18 . The image displaying apparatus according to claim 16 , wherein the control unit limits the setting by reducing an input value for setting the window level and receiving the reduced input value.

19 . A method of controlling an image displaying apparatus, the method comprising the processes of:
acquiring an object image to be displayed; determining whether the object image to be displayed is a predetermined display type, a reference value of which is allocated to a particular pixel value; setting a window level and a window width for displaying the object image to be displayed, and fixing the window level to a predetermined value when the determining process determines that the object image to be displayed is the predetermined display type; and converting the object image to be displayed so that the object image to be displayed is displayed with the window level fixed to the predetermined value or the set window level and with the set window width.

20 . A storage medium storing a computer program configured to cause a computer to execute the processes of the method of controlling an image displaying apparatus according to claim 19 .

21 . A method of controlling an image displaying apparatus, the method comprising the processes of:
acquiring an object image to be displayed; controlling a display unit to display the object image to be displayed with a predetermined window level and a predetermined window width; and resetting the predetermined window level and the predetermined window width, wherein, when the object image to be displayed is a display type of an image, a reference value of which is allocated a particular pixel value, setting of the window level in the resetting process is limited in a mode in which the predetermined window level and the predetermined window width are both reset through a single operation.

22 . A storage medium storing a computer program configured to cause a computer to execute the processes of the method of controlling an image displaying apparatus according to claim 21 .

23 . An image displaying apparatus comprising:
a receiving unit configured to receive change of a window level and a window width by a user when an object image to be displayed is displayed; and a changing unit having a mode in which the window level and window width of the object image to be displayed are changed in accordance with the change of the window level and the window width by the user, and a mode in which only the window width of the object image to be displayed is changed in accordance with the change of the window level and the window width by the us
