Abstract: The synthesizing circuit inputs signals representing the brightness coefficient K2 and the brightness coefficient K3 from the multiplexer, and inputs the overscanned frame image data D1 in pixel units from the first latch circuit. When the start frame image read the third time and the after frame image read the first time are input simultaneously, the synthesizing circuit calculates the brightness coefficient K2 for the brightness value of the pixels of the start frame image, and calculates the brightness coefficient K3 for the brightness value of the pixel of the after frame image. Then, it synthesizes the pixels of the start frame image and the pixels of the after frame image for which the respective brightness coefficients were calculated, and generates the intermediate frame image data D2. As a result, it moving image flicker is suppressed using an easier method than in the past, and it is possible to realize smoother moving image display.

Abstract: A specific phase position detection circuit of the invention includes: a measurement unit that detects two time positions where a signal level of an analog signal is matched with a preset threshold value, as a first reference position and a second reference position in each cycle of the analog signal, and measures a time length between the first reference position and the second reference position, as a reference time period; a computation unit that computes a time period at a preset rate to the reference time period measured in each previous cycle, as an additional time period in each current cycle of the analog signal; and a detection unit that detects a time position shifted from the first reference position detected in a current cycle by the additional time period computed by the computation unit, as the specific phase position, and outputs a detection signal representing the detected specific phase position. The positions having the substantially fixed positional relations to the peak positions are detectable as the specific phase positions in the respective cycles of an analog signal. The technique of the invention thus enables accurate specification of the peak positions even in the analog signal with varying amplitude.
