A camera device without an image displaying function which is adapted to assemble with a portable electronic device with a vision displaying module is disclosed in the present invention. The camera device is electrically connected to the portable electronic device via wire/wireless connection. The camera device includes a base, a lens module and at least one touch navigation module. The base includes a surrounding component whereinside the lens module is disposed. The lens module includes a lens assembly and a digital processing unit. The touch navigation module is disposed on an outer surface of the surrounding component and electrically connected to the lens module. The touch navigation module detects an input command to trigger the lens assembly to capture an image, or controls parameters of an adjustable mode of the lens assembly via the digital processing unit.

Camera device without image displaying function

A keyboard with a distance detecting function includes a plurality of keyswitches, and each keyswitch includes a keycap, a base, a supporting component, a recovering component and a distance detecting unit. The base has a guide slot structure. The supporting component has a first end connecting to the keycap, and a second end movably assembled with the guide slot structure. The recovering component is disposed between the supporting component and the guide slot structure. The distance detecting unit is detachably disposed on the base, and adapted to detect a movement of the keycap relative to the base for determining whether the keyswitch is actuated.

An input device comprising an optical module having a light guide plate, a light source, a scattering layer and a sensor is provided. The light guide plate has a top surface, a bottom surface, and a side. The light source emits a light to the side. The light travels within the light guide plate. The scattering layer changes a path of parts of the light on the bottom surface so that the light is projected out of the top surface to form a penetrating light. When an object approaches or touches the top surface of the light guide plate, at least a part of the penetrating light is reflected by the object to form a reflected light received by the sensor. According to the reflected light, the input device generates a position signal indicating at least one relative position of the object with respect to the top surface.

An optical touch control apparatus, for detecting displacement between an object and the optical touch control apparatus. The optical touch control apparatus comprises: an object detecting apparatus, for detecting the object to generate an object image, having a first detecting area in a first mode and having a second detecting area in a second mode, wherein the first detecting area is larger than the second detecting area; an image sensor, for capturing at least one frame of the object image; and a control unit, for adjusting an image capturing area of the image sensor, according which one of the first detecting area and the second detecting area the object detecting apparatus utilizes.

Optical touch control apparatus and adjustable light guide apparatus

There is provided an optical raindrop detector including a light source, a light guide, an image sensor and a processing unit. The light source alternatively emits light with different brightness values. The light guide has an incident surface, a detection surface and an ejection surface, wherein the light source emits incident light into the light guide via the incident surface, and a plurality of microstructures are formed on the ejection surface to reflect the incident light to become scattered light toward the detection surface. The image sensor receives reflected light formed by raindrops in front of the detection surface reflecting the scattered light to penetrate the light guide and eject from the ejection surface, and generates image frames corresponding to the different brightness values of the light source. The processing unit calculates differential images of the image frames to accordingly identify rain intensity.
