Abstract:
A scanner lens includes a first lens, a second lens, and a third lens. The first lens is provided with a first focal length. The first, second, and third lenses are sequentially arranged from an object end to an imaging end and are respectively provided with a plus diopter, a minus diopter, and a plus diopter. At least one of the first, second, and third lenses comprises an aspheric lens. The ratio of the first focal length to a system focal length of the scanner lens ranges between 1 and 2.

Abstract:
A micro prime lens system is provided. From an object side to an image side, the micro prime lens system sequentially includes a first lens, a second lens, a third lens and a fourth lens, which have a positive, a negative, a positive and a negative index of refraction, respectively. The third lens is an aspherical lens made of glass material and conforms to the following condition: 0.3
Abstract:

From an object end to an image end thereof, the mini fixed focus lens module sequentially includes a first lens, a second lens, a third lens and a fourth lens. The first lens has a positive diopter, the second lens has a negative diopter, the third lens has a positive diopter, the fourth lens has a negative diopter, a combined diopter of the second and third lenses is positive, and the mini fixed focus lens module satisfies the following formula: 0.2
Abstract:
A method of playing an original 3D content on a 3D enabled monitor, where the 3D enabled monitor does not support the original 3D format type of the original 3D content. The method includes the steps of automatically reading a portion the original 3D content to obtain an identity of the original 3D format type, this portion may or may not be a tag, and reading this portion may include playing multiple frames of the 3D content. The preferred method further includes automatically detecting a monitor and its 3D display format type. If no match is found between the original 3D format type and the display format type, then the method deconstruct the original image content and reconstruct the image content into a 3D format type supported by the 3D display format type.
Abstract:
An electronic device, a display device, and a method of controlling audio/video output of the electronic device are disclosed. The electronic device includes a data processing unit, a visual output unit, an audio output unit, and a user operating habit database. The data processing unit executes an application program, the visual output unit outputs an image signal, the audio output unit outputs an audio signal, and the user operating habit database records a corresponding relationship between different program types and operating parameters of the visual output unit or the audio output unit. And, the data processing unit acquires the program type of the application program being run for controlling the operating parameters of the visual output unit or the audio output unit.
Abstract:
The present invention discloses an electronic device and power saving method thereof. In an embodiment, when the electronic device operates in a power-saving mode, which means an area on a screen of the electronic device is not a currently in-focus window-based interface, the area is adjusted to have reduced backlight brightness. Thus, not only the power consumed by the screen is reduced but also user experience can be maintained. In another embodiment, when the electronic device operates in a power-saving mode, display parameters for an image shown in the currently in-focus window-based interface are changed without adversely affecting the power-saving effect, so that the currently in-focus window-based interface has higher display definition than other areas do.
Abstract:
A method for displaying on-screen display (OSD) image, suitable for a display apparatus, is provided. In the present invention, the OSD image is enabled for showing a setting menu of the display apparatus. The setting menu includes many items. When one of the items is selected, whether the selected item is valid is determined according to a current using state of the display apparatus. If the selected item is valid, a function corresponding to the selected item is executed. If the selected item is not valid, a suggestive block is displayed on the OSD image.
Abstract:
A lens module of a scanner is provided, including a first lens with a positive diopter, a second lens with a negative diopter, a third lens with a positive diopter, and a fourth lens with a negative diopter. The first, second, third, and fourth lenses are sequentially arranged from an object end to an image end of the lens module, and at least one of the first and fourth lenses is an aspheric lens. The fourth lens has a focal length f4 and an objective side surface with a radius of curvature R7, wherein 0.1
Abstract:
A method for compensating light reflection of a projection frame and a projection apparatus is provided. In the method, a preset frame is projected by the projection apparatus. Next, a spectrum of a light reflected by the projected preset frame is detected and compared with an original spectrum of the preset frame. A light characteristic value of the projected preset frame is then adjusted accordingly, so as to compensate a difference between the detected spectrum of the reflected light and the original spectrum.
