DETAILED DESCRIPTION OF THE INVENTION
The image-capturing devices disclosed by the present invention include, but not limited to, mobile phones, digital cameras, PDAs and other electronic products having image-capturing function. In the following detailed description of the present invention, a digital camera is taken as a preferred embodiment of the present invention. The accompanied drawings are only for reference and illustration and not for limiting the present invention.
FIG. 1 and FIG. 2A are respectively an exploded schematic view and an assembled schematic view of the image-capturing device 100 according to the first embodiment of the present invention. As shown in the figures, the image-capturing device 100 comprises a shutter button 110 and a focus button 120. The shutter button 110 is disposed on one side of the upper case of the image-capturing device 100 to capture an image. The focus button 120 is disposed on a position where a circuit board of the image-capturing device 100 faces the front case, and in a range where a user may press the shutter button 110 without moving the hand, so as to perform the function of focusing an image.
Referring to FIG. 1 and FIG. 2A, the focus button 120 is a pyroelectric IR sensor which can sense the infrared rays from human bodies. Once the infrared sensor senses the infrared rays from human bodies, it generates a signal change to control the image-capturing device 100 to perform the image focusing function of the focus button 120. A through hole 130 corresponding to the focus button 120 is opened in the front case of the image-capturing device 100, so as to facilitate the user to press the position corresponding to the focus button 120. In order to protect the infrared sensor used as the focus button 120 from being contaminated with dust from the exterior, thereby influencing the sensitivity, and prevent liquid from flowing into the image-capturing device 100 through the through hole 130, thereby causing a short circuit of the internal electronic components, a transparent cover 131 is embedded into the through hole 130. The material of the transparent cover 131 is a transparent material that will not degrade the sensing efficiency of the focus button 120, such as acrylic or glass.
As shown in FIG. 2B, the shutter button 110 is a single-stage switch used as an interface to capture an image. The structure of the single-stage switch is simpler than the two-stage switch and thus may capture an image more exactly. Furthermore, the price of the single-stage switch is low, and thus the manufacturing cost is reduced if the single-stage switch is employed in the image-capturing device 100.
As shown in FIG. 2A and FIG. 3, when the user holds one side of the image-capturing device 110 and the finger just touches the through hole 130 corresponding to the focus button 120, the focus button 120 senses the change and then outputs a triggering signal, such that the image-capturing device 100 focuses an image automatically. The user observes the image to be captured through a display screen (not shown) and then presses the shutter button 110 to shoot the image clearly after the image is fully focused.
FIG. 4 and FIG. 5A are respectively an exploded schematic view and an assembled schematic view of the image-capturing device 100 according to the second embodiment of the present invention. As shown in the figures, the image-capturing device 100 comprises a shutter button 110 and a focus button 120. The shutter button 110 is disposed on one side of the upper case of the image-capturing device 100 to perform the image capturing function. The focus button 120 is disposed on the image-capturing device 100 opposite to the upper case and adjacent to the shutter button 100. Furthermore, the focus button 120 is also in a range where a user may press the shutter button 110 without moving the hand, so as to perform the image focusing function.
Referring to FIG. 5B, the focus button 120 is a pyroelectric IR sensor. A through hole 130 corresponding to the focus button 120 is opened in the case of the image-capturing device 100, and a transparent cover 131 is embedded into the through hole 130. The material of the transparent cover 131 is transparent material that will not degrade the sensing efficiency of the focus button 120, such as acrylic or glass. The shutter button 110 is a single-stage switch used as an interface to capture an image.
As shown in FIG. 5A and FIG. 6, when the user holds one side of the image-capturing device 100 and puts one of his/her fingers on the shutter button 110, the finger must cross over the through hole 130 corresponding to the focus button 120 firstly. When the focus button 120 senses the change, it outputs a triggering signal to make the image-capturing device 100 focuses an image automatically. The user observes the image to be captured through a display screen (not shown) and then presses the shutter button 110 to shoot the image clearly after the image is fully focused.
It should be noted that the focus button 120 disclosed by the present invention is disposed on the upper case and one side of the front case of the image-capturing device 100; however, it is not intended to limit the present invention, and those skilled in the art may change and design the focus button 120 to be in any position where the focus button 120 may be triggered to focus an image before the user presses the shutter button.
The present invention solves the problem that the object of focusing and shooting cannot be achieved only if the two-stage pressing operation mode is employed in the digital camera of the conventional art. Through the present invention, an image can be focused more conveniently, rapidly and exactly and the situation that an image which is shot by the user is often blurred is avoided.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
