Abstract

A display control apparatus that makes it easy to recognize a target image when images are displayed in each of regions obtained by dividing a single screen, even when the method for dividing the screen has changed. For example, when the method for dividing the screen in an index view is switched, the post-switch location of a target thumbnail image is calculated based on the ratio between the pre- and post-switch division numbers and the pre-switch location of the target thumbnail image, in both the horizontal and vertical directions. Then, the overall arrangement of the thumbnail images in the index view after the division method switch is determined based on the calculated location of the target thumbnail image.

First claim

What is claimed is:

1. A display control apparatus comprising:
a display control unit that performs control so that multiple display items arranged in a matrix made up of multiple columns and multiple rows are displayed in a display unit;
a changing unit that changes the matrix for arranging the multiple display items displayed by the display control unit from a first matrix to a second matrix in which the number of columns, rows, or both columns and rows is different from the first matrix; and
a control unit that, when a change is performed by the changing unit, decides a reference column and row in the second matrix such that a displayed position, on the display unit, of the reference column and row corresponds to a displayed position, on the display unit, of a column and row in which a focused-on display item in the first matrix is located, and controls the display control unit to arrange the multiple display items in the second matrix so that the focused-on display item is located in the reference column and row,
wherein a location in which the focused-on display item is located in the second matrix under the control by the control unit differs depending on a location in which the focused-on display item is located in the first matrix.

2. The display control apparatus according to claim 1 , wherein the control unit includes a calculation unit that calculates the reference column and row based on the column and row in which the focused-on display item is located in the first matrix, the number of columns and rows in the first matrix, and the number of columns and rows in the second matrix.

3. The display control apparatus according to claim 2 , wherein the calculation unit calculates the reference row and column so that the ratio between the reference row and the number of rows in the second matrix corresponds to the ratio between the row in the first matrix in which the focused-on display item is located and the number of rows in the first matrix, and so that the ratio between the reference column and the number of columns in the second matrix corresponds to the ratio between the column in the first matrix in which the focused-on display item is located and the number of columns in the first matrix.

4. The display control apparatus according to claim 1 , wherein the reference row is a row based on a value obtained by dividing the number of rows in the second matrix by the number of rows in the first matrix and then multiplying the resultant of that division by the value of the row in the first matrix in which the focused-on display item is located, and
wherein the reference column is a column based on a value obtained by dividing the number of columns in the second matrix by the number of columns in the first matrix and then multiplying the resultant of that division by the value of the column in the first matrix in which the focused-on display item is located.

5. The display control apparatus according to claim 1 , wherein in the case where the row in the first matrix in which the focused-on display item is located is a row at an end of the first matrix, the control unit uses, as the reference row, the row at the end of the second matrix that corresponds to the row at the end of the first matrix in which the focused-on display item is located, and
wherein in the case where the column in the first matrix in which the focused-on display item is located is a column at an end of the first matrix, the control unit uses, as the reference column, the column at the end of the second matrix that corresponds to the column at the end of the first matrix in which the focused-on display item is located.

6. The display control apparatus according to claim 1 , wherein when a change is performed by the changing unit, the control unit controls the display control unit to arrange the multiple display items in the second matrix in a specific order so that the focused-on display item is located in the reference column and row.

7. The display control apparatus according to claim 1 , further comprising:
a recording control unit that performs control so that a pair of the column and row of the focused-on display item in a matrix is recorded into a storage unit in association with that matrix, and in the case where the focused-on display item has been changed, pairs of the column and row recorded in association with matrices aside from the current matrix are cleared and the pair of the column and row recorded in association with the current matrix is replaced by a pair of a column and row in which the changed focused-on display item is located in the current matrix,
wherein, in the case where the first matrix has been changed to the second matrix by the changing unit and a pair of a column and row associated with the second matrix is stored in the storage unit, the control unit uses that stored pair of column and row as the reference column and row.

8. The display control apparatus according to claim 1 , wherein, when a change has been made by the changing unit, the display control unit performs control so that an identification display indicating the reference column and row is displayed in the second matrix until the focused-on display item is displayed in the reference column and row in the second matrix.

9. The display control apparatus according to claim 1 , wherein the display control unit performs control so that the focused-on display item located in the reference column and row in the second matrix is displayed at a larger size than the other display items arranged in the second matrix.

10. The display control apparatus according to claim 1 , wherein the display unit includes a touch panel, and
wherein the changing unit performs the change in response to one of the multiple display items arranged in the first matrix and displayed in the display unit being touched.

11. The display control apparatus according to claim 1 , wherein the display control apparatus is a digital camera.

12. The display control apparatus according to claim 1 , wherein the display control apparatus is at least one of a mobile telephone terminal, a mobile image viewer, a display provided in a printer device for selecting and checking images to be printed, and a digital photo frame.

13. The display control apparatus according to claim 1 , wherein the display item includes an image.

14. The display control apparatus according to claim 1 , wherein a displayed position, on the display unit, of the focused-on display item arranged in the second matrix under the control of the control unit is proximate to or the same as a displayed position, on the display unit, of the focused-on display item arranged in the first matrix.

15. The display control apparatus according to claim 1 , wherein, for any display item that is focused-on in the first matrix, a displayed region, on the display unit, of the focused-on display item arranged in the second matrix under the control of the control unit at least partly overlaps a displayed region, on the display unit, of the focused-on display item arranged in the first matrix.

16. The display control apparatus according to claim 1 , wherein the multiple display items in the second matrix is a group of display items which is determined dependent on a column and row in which the focused-on display item in the first matrix is located.

17. A display control method comprising:
a display control step of performing control so that multiple display items arranged in a matrix made up of multiple columns and multiple rows are displayed in a display unit;
a changing step of changing the matrix for arrang
