A data processing circuit is disclosed in the present invention. The data processing circuit includes a decoder and a number of N-stage circuits. The circuits receive input data from at least a memory and separate the input data into N stages. The circuit process and store the N input data simultaneously to decrease the time of data processing in the data processing circuit.

Data processing circuit

An image processing circuit turns off the writing unit of the controller of the DRAM when the previous frame is identical to the current frame. In this way, the writing unit of the controller of the DRAM does not write the current frame into the DRAM, thereby reducing power consumption.

A method for generating an over-drive grey level for driving a pixel includes providing a corresponding over-drive function according to an original grey level for the pixel in the previous frame, and generating the over-drive grey level according to the corresponding over-drive function and the original grey level for the pixel in the current frame.

Method for driving a pixel by generating an over-drive grey level and driver thereof

A timing control circuit with a power-saving function includes a receiving circuit, a processor, and a first switch. The receiving circuit receives a first set of differential signals for generating a set of command signals. The processor is coupled to the receiving circuit and generates a first control signal according to the set of command signals. The switch is coupled between the receiving circuit and the processor for selectively decoupling the receiving circuit from a first power supply according to the first control signal.

A noisy signal analysis in which a threshold value is set to evaluate the presentation of the display device. The analysis can produce the range of noise level of the image for measuring the distortion block of image caused by the display devices. Furthermore, the apparatus includes a step function generator for producing step functions, a transforming unit for changing threshold value in step functions, and a display for showing the image corresponding to both the high value and low value.

Method of noisy signal analysis and apparatus thereof

The invention discloses a gamma image correction method and device that employs an improved interpolating operation, comprising receiving an original image data point; retrieving p conversion values (p is larger than 2) from a memory unit according to the original image data point; and arithmetically processing the p conversion values for generating a gamma corrected image parameter value from the original image data point wherein the original image data point is a N bits data, the memory unit contains 2conversion values and N is lager than k.

Gamma image correction method and device

A graphics display adapter has a row interpolator circuit connected to receive the source pixel data synchronized at a first clock rate and to interpolate groups of pixels of row at a second clock rate. A row interpolated storage device receives and retains interpolated source pixel data of each row at the second clock rate. A column interpolator circuit extracts the interpolated source pixel data at a third clock rate. The column interpolator circuit then interpolates groupings of the interpolated source pixel data at the third clock rate and transmits the destination graphic pixel data for display. The second clock rate maybe equal to the first clock rate or the faster of the first and third clock rates.
