Abstract:
1. An image recording apparatus, comprising: a receiving unit to receive a broadcast signal pertaining to a predetermined broadcast; a recording unit to record video data composed of sound data and image data, both based on the broadcast signal received by the receiving unit; a sound output unit to output a sound based on the sound data; an image display unit to display an image based on the image data; detection unit to detect an end of a predetermined broadcast according to the broadcast signal received by the receiving unit based on a fact that no synchronization signals are included in the broadcast signal, or a fact that the sound data in the broadcast signal is a sound signal having a specific frequency and the image data in the broadcast signal is an image signal for displaying a specific image, or a fact that a rate of a variation of the sound based on the sound data in the broadcast signal is within a predetermined range and a rate of a variation of the image based on the image data in the broadcast signal is within a predetermined range; timer unit to time a detection time for which the detection unit continues to detect the end of the broadcast; judgment unit to judge whether the detection time timed by the timer unit has reached a first elapsed time or not, and to judge whether the detection time has reached a second elapsed time or not; and record erasing unit to stop an output of the sound based on the sound data from the sound output unit when the judgment unit judges that the detection time has reached the first elapsed time, and then to stop a display of the image based on the image data on the image display unit, to stop recording the video data in the recording unit and to erase the video data having been recorded in the recording unit while the timer unit has been timing a predetermined elapsed time when the judgment unit subsequently judges that the detection time has reached the second elapsed time.
