TW563374B - Device and method using adaptive vertical synchronization and alternate display to adjust image resolution - Google Patents

Abstract

The present invention provides a device using adaptive vertical synchronization and alternate display to adjust the image resolution, which includes: a first phase adjustment circuit for generating a first clock; a second phase adjustment circuit for generating a second clock; a reference clock for providing a reference clock of the second phase adjustment circuit; a scanning line buffer area for buffering an image data based on the first clock; a clock adjustment unit for adjusting the image data of the scanning line buffer area based on the second clock for outputting an image with a suitable ratio. The adjustment method includes the steps of: using a scan line lock method to perform the required scaling operation based on the required output resolution when being smaller than a maximum acceptable pixel clock; and defining a scanning factor and performing scanning in an alternate manner when being larger than the maximum acceptable pixel clock.

Description

The purpose of this case is to address the problem of the placement and method of the frame used in Figure 1, so that the display to pixel cl0ck can be smoothly displayed, and the phenomenon of "proposing a new range" appears. In order to achieve the above purpose, this case proposes a device for adjusting image resolution using a suitable library, which includes: a synchronous and interactive display of a first phase adjustment circuit to generate a first clock; a second phase adjustment circuit to generate A second time and a reference clock, so as to provide the second phase adjustment wire, f punching area, to temporarily store according to the -clock; a M / M order το, according to the second clock capacity, = The image data of the bucket is used to output a suitable proportion of the image. In Guan Guan, the line drawing buffer is used as described to adapt to vertical synchronization and interactive loop.): ≪ (LL ^ 5 Phase Lock Adjusting the image resolution as required by direct synchronization and interactive age: The first phase adjustment circuit in China and China is a phase-locked loop (PLL, Phase㈣ device such as ϊ = ί = ϊίί4 · ϊ ^ mutual display for image analysis The lack of adjustment of households: 7-5, should be vertical The step and interactive display are used to adjust the image resolution. Among them, the 线 I field line buffer can temporarily store the image data of seven scan lines. As mentioned, use a taxi that adapts to vertical synchronization and interactive display to adjust the image resolution. The clock adjustment unit adjusts the Scaling of the image data in the scan line buffer. This case also proposes a method for adjusting image resolution using adaptive vertical synchronization and interactive display, including the following steps: : _ When it is less than a maximum acceptable pixel clock, according to the required output resolution, use the line lock method to do the required scaling (Scaling) action; and exceed this When the maximum acceptable pixel clock is defined, a scanning factor is defined, and the scanning is performed in an alternate manner. As described, the method of adjusting image resolution using adaptive vertical synchronization and interactive display is described, wherein the interaction (Alternate) method is to divide the picture into a plurality of sub-areas
