7. The biometric imaging device as claimed in claim 4 , wherein the processor controls the camera to capture a first biometric image of a first portion of the palm of the user inside the fixed capture area according to detection of a touch to the first touch location, and controls the camera to capture a second biometric image of a second portion of the palm of the user inside the fixed capture area according to detection of a touch to the second touch location.

8. The biometric imaging device as claimed in claim 1 , wherein

the processor controls the touchscreen panel to display a move instruction to move a touch location to be touched by the user, as the operating position.

9. The biometric imaging device as claimed in claim 8 , wherein the move instruction includes a display of a moving route of the touch location on the touchscreen panel.

10. The biometric imaging device as claimed in claim 8 , wherein the move instruction is a slide instruction to move the touch location by sliding two or more fingers of the user on the touchscreen panel.

11. The biometric imaging device as claimed in claim 10 , wherein the processor performs a process including

under a condition that an input is made with respect to at least one touch location amongst a plurality of touch locations displayed on the touchscreen panel, updating a touch location for guiding a next touch on the touchscreen panel for all of the plurality of touch locations, and

under a condition that an input is simultaneously made with respect to two or more touch locations amongst the plurality of touch locations displayed on the touchscreen panel, judging a start of capturing the biometric image of the palm of the user by the camera.

12. The biometric imaging device as claimed in claim 8 , wherein the move instruction is a slide instruction to move the touch location by sliding at least one finger on the touchscreen panel by at least one of a linear, a Z-shaped, a rectangular shaped, a circular or oval-shaped, and a triangular shaped sliding movement on the touchscreen panel.

13. The biometric imaging device as claimed in claim 1 , wherein

the processor controls the touchscreen panel to display a move instruction to move a touch location to be touched by the user, as the operating position, and

the move instruction includes a display of a moving route of the touch location on the touchscreen panel to instruct sliding two or more fingers of the user on the touchscreen panel, so that the camera captures the biometric image of the palm in an area larger than the fixed capture area of the camera as the two or more fingers of the user slide on the touchscreen panel.

14. A terminal apparatus comprising:

the biometric imaging device as claimed in claim 1 ; and

the touchscreen panel.

15. A biometric imaging method comprising:

detecting, by a touchscreen panel that is provided on a surface of a casing, an input to the touchscreen panel;

outputting, by a processor, an instruction that instructs an operation position of at least one finger of a user on the touchscreen panel to display the operation position on the touchscreen panel based on the instruction, in response to detection of a first input to the touchscreen panel; and

controlling, by the processor, a camera that has a fixed capture area and is provided on the surface of the casing in a periphery of the touchscreen panel, to capture a biometric image of a palm of the user inside the fixed capture area at a timing, after the detection of the first input, when the touchscreen panel detects a second input that is a touch to the operation position displayed on the touchscreen panel by the at least one finger of the user,

wherein the camera is located at a position on the surface of the casing such that at least a portion of the palm of the user is captured inside the fixed capture area in a state in which the at least one finger of the user touches the operation position displayed on the touchscreen panel.

16. The biometric imaging method as claimed in claim 15 , further comprising:

setting, by the processor, the operation position according to a position of the first input on the touchscreen panel.

17. The biometric imaging method as claimed in claim 15 , further comprising:

controlling the touchscreen panel, by the processor, to display a move instruction to move a touch location to be touched by the user, as the operating position,

wherein the move instruction includes a display of a moving route of the touch location on the touchscreen panel to instruct sliding two or more fingers of the user on the touchscreen panel, so that the camera captures the biometric image of the palm in an area larger than the fixed capture area of the camera as the two or more fingers of the user slide on the touchscreen panel.

18. A non-transitory computer-readable storage medium having stored therein a program for causing a computer to execute a process comprising:

detecting an input to a touchscreen panel that is provided on a surface of a casing;

outputting an instruction that instructs an operation position of at least one finger of a user on the touchscreen panel to display the operation position on the touchscreen panel based on the instruction, in response to detection of a first input to the touchscreen panel by one or more fingers of the user; and

controlling a camera that has a fixed capture area and is provided on the surface of the casing in a periphery of the touchscreen panel, to capture a biometric image of a palm of the user inside the fixed capture area of the camera at a timing, after the detection of the first input, when the touchscreen panel detects a second input that is a touch to the operation position displayed on the touchscreen panel by the at least one finger of the user,

wherein the camera is located at a position on the surface of the casing such that at least a portion of the palm of the user is captured inside the fixed capture area in a state in which the at least one finger of the user touches the operation position displayed on the touchscreen panel.

19. The non-transitory computer-readable storage medium as claimed in claim 18 , wherein the process further comprises:

setting the operation position according to a position of the first input on the touchscreen panel.

20. The non-transitory computer-readable storage medium as claimed in claim 18 , wherein the process further comprises:

controlling the touchscreen panel to display a move instruction to move a touch location to be touched by the user, as the operating position,

wherein the move instruction includes a display of a moving route of the touch location on the touchscreen panel to instruct sliding two or more fingers of the user on the touchscreen panel, so that the camera captures the biometric image of the palm in an area lamer than the fixed capture area of the camera as the two or more fingers of the user slide on the touchscreen panel.
