An image conversion device is disclosed, having an image converting circuit for receiving a first and a second image frames of a first format and generating a third and a fourth image frames of a second format; and a signal generating circuit coupled with the image converting circuit for generating a plurality of first synchronization signals having a substantially fixed period and one or more second synchronization signals for the third and the fourth image frames, wherein each of the second synchronization signals is synchronized with one of the first synchronization signals and the third image frame contains at least one more first synchronization signal than the fourth image frame.

Method and apparatus for image conversion

An image displaying method for a television includes: selecting a portion of a plurality of display regions of a screen of the television to display a still or animated image when a power-on signal is received; and utilizing all the plurality of display regions to display images corresponding to a television signal after a predetermined time period beginning from when the power-on signal is received. The present invention further discloses an image displaying method for a television, including: selecting a portion of a plurality of display regions of a screen of the television and stopping the displaying of images corresponding to a television signal on the selected display regions when a power-off signal is received; and stopping the displaying of images corresponding to the television signal on all the plurality of display regions after a predetermined time period beginning from when the power-off signal is received.

Image displaying method and apparatus for television when powering on/off

A method for adjusting a phase of a sampling frequency of ADC is disclosed. The method includes converting an analog signal into a first digital signal according to a first phase of the sampling frequency during a first time interval; calculating a first value according to the first digital signal; converting the analog signal into a second digital signal according to a second phase of the sampling frequency during a second time interval; calculating a second value according to the second digital signal; and adjusting the phase of the sampling frequency according to the first value and the second value.
