Benefits of technology

[0033]The present invention enables notification of an image-pickup action appropriately to individuals around a user of an image-pickup device by light-emission together with an image-pickup operation. At this time, in particular, when an image-pickup distance corresponding to a set operation mode is shorter than an image-pickup distance corresponding to another switchable operation mode, the light from an LED is prevented from going around a sensor of a camera and coming therein. Consequently, the present invention has a new superior effect which suppresses any occurrence of making a picked-up image fuzzy, and can avoid deterioration of an image quality.

Problems solved by technology

However, fraudulent image-pickup, i.e., a secret-image-pickup action increases and becomes a problem in accordance with reduction in size and weight of a camera.

first embodiment

[0053]An explanation will be given of the first embodiment of the present invention with reference to FIG. 1 to FIG. 5. FIG. 1 is a schematic view showing the external configuration of a camera-mounted cellular phone 1 with a piece of light-emission means. FIG. 2 is a block diagram showing the configuration of the camera-mounted cellular phone 1. FIG. 3 is a flowchart showing a light-emission operation of an LED 4 which is the light-emission means. FIG. 4 is a flowchart showing a light-emission control for the LED 4 which is the light-emission means in detail. FIG. 5 is a table summarizing a relation between an operation mode switched and set and the luminous brightness of the LED 4.

[0054]As shown in FIG. 1, the camera-mounted cellular phone 1 comprises a switch 2, a camera sensor 3 which acquires (picks up) an image around the camera-mounted cellular phone 1 (an object), the LED 4 which is the light-emission means, and a shutter button 6. The switch 2 (operation mode setting means)...

second embodiment

[0076]Next, an explanation will be given of the second embodiment of the present invention with reference to FIG. 6 to FIG. 9. FIG. 6 is a schematic view showing the external configuration of a camera-mounted cellular phone 11 with two pieces of light-emission means. FIG. 7 is a block diagram showing the configuration of the camera-mounted cellular phone 11. FIG. 8 is a flowchart showing a light-emission control for two LEDs that are the light-emission means in detail. FIG. 9 is a table summarizing a relation among an operation mode switched and set, the light-emission means, and luminous brightness. Note that, in the second embodiment, the same structural element will be denoted by the same reference numeral as that of the first embodiment.

[0077]FIG. 6 shows the camera-mounted cellular phone 11 equipped with two pieces of light-emission means. The camera-mounted cellular phone 11 comprises the switch 2 which selects an image-pickup distance and switches it at the time of image-pick...

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.

Description

TECHNICAL FIELD[0001]The present invention relates to an image-pickup device with a light-emission operation at the time of image-pickup, an information processing terminal, a cellular phone, a program, and a light-emission control method.BACKGROUND ART[0002]Recently, reduction in size and weight of a camera image-pickup device equipped in a camera or a cellular phone are advanced. In particular, a camera-mounted cellular phone is widespread among general users, and this makes it possible for users to casually pick up an image regardless of a location. However, fraudulent image-pickup, i.e., a secret-image-pickup action increases and becomes a problem in accordance with reduction in size and weight of a camera.[0003]Because of the foregoing problem, a camera-mounted cellular phone has a function of emitting light when picking up an image, or of outputting sound (shutter sound) or the like for preventing secret image-pickup. This allows individuals around a user of the camera-mounted...
