Embodiment Construction

[0017] Below, refer to Figure 1A ~ Figure 4D , one embodiment of the imaging device and the portable device of the present invention will be described.

[0018] Such as Figure 1A ~ Figure 3 As shown, the mobile device 1 of this embodiment is a mobile phone equipped with a digital camera function and an LED flash memory function, that is, an imaging device 2 and a light emitting element driving device 3 . Furthermore, a mobile device (hereinafter referred to as “mobile phone”) 1 includes a first body 4 and a second body 6 that is freely foldable with the first body 4 via a hinge mechanism 5 .

[0019] The first main body 4 has an operation key section 7 including numeric keys and the like for inputting operations of the mobile phone 1 and a microphone 8 for inputting voice calls on the inner surface side when the mobile phone 1 is folded. In addition, in the first main body 4, a speaker 9 for notifying the status of an incoming call or the like is provided on the outer surf...

Abstract

The disclosed imaging device is provided with: a light emitting unit which emits light in the direction of the object to be imaged; a lens which moves a displacement region corresponding to a focus region; an imaging element which receives light via the lens; and a lens control device which acquires imaging data received by the imaging element and controls the position of the lens. The lens control unit moves the lens in stages to acquire the imaging data of each field in the focus region. The imaging device is further provided with a light emission control unit, which changes the amount of light emitted by the light emitting unit in response to the focus position of the lens in each field.

Description

technical field [0001] The present invention relates to an imaging device including a lens movable in the optical axis direction, an imaging element receiving light through the lens, and a portable device including the imaging device. Background technique [0002] Conventionally, as an imaging device, an imaging device including a lens movable in the optical axis direction and an imaging element receiving light through the lens is known (for example, refer to Patent Document 1). Such an imaging device controls the position of the lens in stages in order to acquire imaging data for each field in the focus area. Then, as the lens moves, it is confirmed that the focus evaluation value (for example, brightness of imaging data, etc.) decreases, and the lens position at which the focus evaluation value starts to decrease is recognized as the target position. [0003] However, in the imaging device disclosed in Patent Document 1, when capturing imaging data in each field of the fo...
