摘要:
An electronic device and camera module are described. The camera module includes a housing for housing components of the camera module. The housing has a top side which defines an opening. The camera module also includes a lens barrel housed by the housing and having one or more lens elements and an actuator housed by the housing and engaging the lens barrel. The actuator is configured to move the lens barrel to a first position in which at least a portion of the lens barrel extends through the opening. The camera module also includes an image sensor for receiving light which passes through the lens elements of the lens barrel. The image sensor is configured to produce an electronic signal based on the received light. The electronic device also includes a processor electrically connected to the camera module for receiving the electronic signal from the image sensor.

In a system and method for updating a real-time map, operating environment information of a terminal device, which is basic information for update condition determination, is collected, an update condition of a terminal device, which includes one or more of a state of travel, a travel speed, and a network state, is checked by comparing the collected operating environment information with preset criteria, and map data, which is stored in the terminal device, in a combination of one or more of level, tile, and layer units corresponding to the checked update condition, is partially updated.

According to the present invention, an asymmetric elliptical chain gear (10) is characterized by having a shape formed by a combination of: a first ellipse (1) the major axis of which is located on the X-axis of a vertical coordinate system and the minor axis of which is located on the Y-axis of the vertical coordinate system; a first straight line (3) which is perpendicular to the minor axis, and which intersects the first ellipse (1); and a second ellipse (2) which exists on the first straight line (3) and which passes first inflection points (A, A′) that form a fixed angle (a) with respect to the minor axis in the clockwise direction, and which contacts ellipse contact points (B, B′) on the first ellipse (1) that are located at points forming a fixed angle (b) in the clockwise direction. The asymmetric elliptical chain gear (10) of the present invention has a shape formed by a combination of a straight line section ranging from a second reflection point (C), which is a cross point between the first straight line (3) and the first ellipse (1), to the first inflection point (A); a second ellipse section ranging from the first inflection point (A) to the ellipse contact point (B); and a first ellipse section ranging from the ellipse contact point (B) to the second inflection point (C′).

A camera module is provided for an electronic device, such as a wireless mobile station or standalone device. The camera module includes a low F-stop lens assembly that is translatable into a desired position. An image of a subject is provided to an EDOF assembly, including a sensor assembly, and an extended-depth-of-field processor. The extended-depth-of-field processor provides for formation of a resultant, recorded image that exhibits improved depth of field characteristics.

A camera unit and method of control are described. The camera unit has a camera flash sub-unit configurable to emit flash light having an adjustable characteristic. A camera sensor sub-unit generates raw color data when exposed to light for processing into a digital image. The camera unit also includes a camera controller for coordinating operation of the camera flash sub-unit and the camera sensor sub-unit. The camera controller monitors one or more ambient light characteristics in a vicinity of the camera unit. Prior to receiving a command instructing the camera unit to generate the digital image, the camera controller repeatedly configures the camera flash sub-unit based on the monitored ambient light characteristics to adjust the characteristics of the emitted flash light. Once the camera controller receives the command, the camera sensor sub-unit is instructed to expose an image sensor using the pre-adjusted camera flash light to increase illumination.

An optical navigation device, such as an optical navigation joystick or mouse, includes an internal redirector which may be separate or formed from material of a touch surface of the optical device. The redirector is disposed at an angle with respect to a plane of the touch surface, operative to reflect light which would otherwise strike the touch surface at a low angle and be internally reflected. The light may be reflected in a direction away from a light sensor of the device, reducing sensed internally reflected light, or may be reflected into the touch surface at a higher angle, potentially increasing a quantity of good signal. The redirector may also include portions which block light directly emitted from a light emitter, or reflected off other surfaces of the navigation device.
