摘要： A 3-dimensional image is generated from an input 2-dimensional image based upon illuminative characteristics of the input image by filtering the 2-dimensional input image with filters of different orientations, outputting base shading images corresponding to the filters, extracting positive pixel values for each base shading image, calculating a difference between the pixel values of the input image and the extracted positive pixel values, calculating a median value of the calculated difference, selecting the filter to output a base shading image of smallest median, outputting a shading image by filtering the input image with the selected filter, combining the input image with the shading image and outputting the 3-dimensional image based upon the combined image. A previously selected filter for a preceding image can be considered when selecting a filter for a current image, enabling generation of 3-dimensional moving pictures.

摘要： A liquid crystal display (LCD) and method of adjusting brightness for the LCD are provided. The LCD includes a light emitter including a plurality of luminescent bodies which are divided into a predetermined number of partial areas, a backlight driver connected to the light emitter to control the brightness of each of the partial areas of the light emitter, and a controller for calculating a representative value for adjusting the brightness of each of the partial areas of the light emitter in accordance with an input image signal and outputting the representative value as a brightness adjustment signal for adjusting the brightness of each of the partial areas to the backlight driver. Thus, the brightness of each of partial areas of a backlight can be adjusted in accordance with the input image signal to improve a contrast ratio. Also, a representative value to be used for adjusting the brightness of each of the partial areas can be lowered by a predetermined ratio to effectively reduce power needed for lighting the backlight. Also, light loss and light gain occurring between neighboring partial areas can be compensated to improve the contrast ratio, and image artifacts can be reduced.

摘要： A display apparatus having a liquid crystal panel, comprises a light source part comprising a plurality of point light sources for supplying light to the liquid crystal panel. The light source part is partitioned into a plurality of light source zones. A light source driving part supplies power to the light source part. A plurality of channel parts sense luminescence of the point light sources for each of the light source zones and output light-emission information of the point light sources based on the sensed luminescence. A controller compares the light-emission information output from the plurality of channel parts with a pre-set reference value. If a difference between the light-emission information and the reference value is out of a predetermined allowable range, the controller sequentially adjusts PWM control signals which are output to the light source driving part, for each of the light source zones.

摘要： A spiral lens disk and a projection system adopting the same are provided. The spiral lens disk has spirally arranged cylinder lens cells and scrolls incident light by converting the rotation of the cylinder lens cells into rectilinear motion of a cylinder lens array. The projection system includes at least one spiral lens disk such that color scrolling is achieved using a single component to form a color image. Due to a reduction in the number of components, a light, low-price projection system can be obtained, and a single-panel projection system with high light efficiency can also be obtained.
