Abstract
A camera-mounted cellular phone (1) comprises a camera sensor (3) which picks up an image, a switch (2) which is configured to switch and set at least equal to or more than two operation modes each corresponding to an image-pickup distance from the camera sensor (3) to an object, and an LED (4) which emits light together with an image-pickup. At the time of image-pickup, an image-pickup operation is performed by controlling a focal point of the camera sensor (3) in accordance with an operation mode switched and set by the switch (2), and the luminous brightness of the LED (4) is controlled in accordance with the operation mode switched and set.
Claims5
An image-pickup device comprising a camera unit which picks up an image, a first light-emission unit which emits light together with an image-pickup operation by the camera unit, and a second light-emission unit which is arranged apart from the camera unit relative to the first light-emission unit and which emits light together with an image-pickup operation by the camera unit, the image-pickup device further comprising:
- an operation mode setting unit which is configured to switch and set a first operation mode corresponding to a first image-pickup distance from the camera unit to an object and a second operation mode corresponding to a second image-pickup distance longer than the first image-pickup distance;
- a camera control unit which performs an image-pickup operation by controlling a focal point of the camera unit in accordance with an operation mode switched and set by the operation mode setting unit;
- and
- a light-emission control unit which only controls the second light-emission unit to emit light when the operation mode setting unit switches and sets the first operation mode, and controls only the first light-emission unit to emit light when the operation mode setting unit switches and sets the second operation mode, wherein the light-emission control unit controls the first light-emission unit or the second light-emission unit to emit light at respective different brightnesses corresponding to the operation mode switched and set by the operation mode setting unit.
A non-transitory recording medium storing a program which allows a control unit of an image-pickup device comprising a camera unit that picks up an image, a first light-emission unit which emits light together with an image-pickup operation by the camera unit, and a second light-emission unit which is arranged apart from the camera unit relative to the first light-emission unit and which emits light together with an image-pickup operation by the camera unit to function as:
- an operation mode setting unit which is configured to switch and set a first operation mode corresponding to a first image-pickup distance from the camera unit to an object and a second operation mode corresponding to a second image-pickup distance longer than the first image-pickup distance;
- a camera control unit which performs an image-pickup operation by controlling a focal point of the camera unit in accordance with an operation mode switched and set by the operation mode setting unit;
- and
- a light-emission control unit which controls the second light-emission unit to emit light when the operation mode setting unit switches and sets the first operation mode, and controls only the first light-emission unit to emit light when the operation mode setting unit switches and sets the second operation mode, wherein the light-emission control unit controls only the first light-emission unit or the second light-emission unit to emit light at respective different brightnesses corresponding to the operation mode switched and set by the operation mode setting unit.
A method of controlling light-emission of light-emission unit in an image-pickup device comprising a camera unit which picks up an image, a first light-emission unit which emits light together with an image-pickup operation by the camera unit, and a second light-emission unit which is arranged apart from the camera unit relative to the first light-emission unit and which emits light together with an image-pickup operation by the camera unit, the method comprising:
- an operation mode setting step to switch and set a first operation mode corresponding to a first image-pickup distance from the camera unit to an object and a second operation mode corresponding to a second image-pickup distance longer than the first image-pickup distance;
- a camera control step to perform an image-pickup operation by controlling a focal point of the camera unit in accordance with an operation mode switched and set by the operation mode setting step;
- and
- a light-emission control step to control the second light-emission unit to emit light when the operation mode setting unit switches and sets the first operation mode, and to control the first light-emission unit to emit light when the operation mode setting unit switches and sets the second operation mode, wherein
- the light-emission control step controls only the first light-emission unit or the second light-emission unit to emit light at respective different brightnesses corresponding to the operation mode switched and set by the operation mode setting step.
