Portable apparatus

1. A portable apparatus having a photographing function, said portable apparatus comprising:

a first detector that detects a movement in a first direction;

a second detector that detects a movement in a second direction which is different from said first direction; and

a controller that switches between performance and suspension of a first and a second functions according to the combination of movements in said first and second directions detected by said first and second detectors, said first and second functions being different from each other, wherein

said controller performs said first and second functions when first and second predetermined movements are detected when the first and second functions are suspended, respectively, said first and second predetermined movements being different from each other and are a combination of movements that include movements in the first and second directions, and wherein

said controller suspends said first and second functions when said first and second predetermined movements are detected when said first and second functions are performed, respectively.

2. A portable apparatus according to claim 1 , wherein said portable apparatus has a plurality of functions, and a single function can be selected as said first function from among said plurality of functions.

3. A portable apparatus according to claim 1 , wherein said controller is configured to switch between performance and suspension of said first and second functions, respectively, without operation of a physical button or other dedicated user input device.

4. A portable apparatus having a photographing function, said portable apparatus comprising:

a first detector that detects a movement in a first direction;

a second detector that detects a movement in a second direction which is different from said first direction; and

a controller that switches between performance and suspension of a first function when said first detector detects movement in said first direction and switches between performance and suspension of a second function when said second detector detects movement in said second direction, said first and second functions being different from each other, wherein

said controller performs the first and second functions when said first and second detectors detect movement in said first and second directions when said first and second functions are suspended, respectively, and wherein

said controller suspends the first and second functions when the first and second detectors detect movement in the first and second directions when the first and second functions are performed, respectively.

5. A portable apparatus according to claim 4 , wherein said portable apparatus has a plurality functions, and a single function can be selected as said first function from among said plurality of functions.

6. A portable apparatus according to claim 4 , further comprising a determiner that determines whether or not said movement in said first direction detected by said first detector is due to unintentional hand shake, said controller switching between performance and suspension of said first function when said determiner determines that said detected movement in said first direction is movement different from movement due to unintentional hand shake.

7. A portable apparatus according to claim 6 , wherein said first detector detects a first velocity, said first velocity is velocity of said movement in said first direction, and said determiner determines that said movement in said first direction is movement different from movement due to unintentional hand shake when said first velocity exceed a threshold value.

8. A portable apparatus according to claim 7 , wherein said first detector comprises an imaging device and a distance detector, said imaging device successively photographs at predetermined intervals, said distance detector detects the movement direction and movement distance of a partial image within two successive images, said partial image is a part of the entire image photographed by said imaging device, and said first detector detects said first velocity based on said movement direction and said movement distance.

9. A portable apparatus according to claim 4 , wherein said controller is configured to switch between performance and suspension of said first and second functions, respectively, without operation of a physical button or other dedicated user input device.
