Patent ID: 7265741

Claim:
A hold-type display device, which continues display of an image for a prescribed display interval, comprising: a conversion unit operable to convert an input image signal into a high-frequency signal including: a high-frequency image signal obtained by increasing the frequency of the image signal; and a black display signal for the display of black; a generation unit operable to generate a timing signal to change a write timing in a prescribed interval of the high-frequency image signal and the black display signal, in order to modify a ratio, within the prescribed interval, of: an interval for image display by said high-frequency image signal; to an interval for black display by said black display signal; a display unit operable to modify the write timing of the high-frequency image signal and black display signal of the high-frequency signal converted by said conversion unit according to the timing signal generated by said generation unit, and to display the image; a reception unit operable to receive television broadcast signals including electronic program guide information; an extraction unit operable to extract electronic program guide information from the television broadcast signal received by said reception unit; and a decision unit operable to decide the type of broadcast program based on the electronic program guide information extracted by said extraction unit and to output a ratio modification signal to change the ratio of the image display interval by said high-frequency image signal to the black display interval by said black display signal, according to the broadcast program type decision; and wherein said generation unit includes a generation unit for programs operable to generate said timing signal according to the ratio modification signal output from said decision unit.
