Zusammenfassung:In a video signal transmitter apparatus that removes a part of a blanking interval of a video signal, generates a converted video signal, based on the video signal including an active interval including video data and the blanking interval excluding the video data, a frequency divider divides a frequency of a pixel clock in synchronization with the video signal by a ratio of transmission frequency division, generate and output a frequency-divided clock as a converted pixel clock. A controller controls a first storage unit to write the video signal for the active interval of the video signal, and read the video signal for the active interval of the converted video signal and output a read video signal as the converted video signal, and to remove a part of a signal included in a horizontal blanking interval existing periodically every horizontal line for the blanking interval of the video signal.
