摘要:
An electronic camera that reduces the consumption of electricity when an image is displayed on an LCD and is able to perform other signal processing at a high speed. Image data captured through an imaging unit is stored in an image memory and is then read from the image memory continuously or intermittently to an LCD drive circuit through a signal processing circuit and a video output circuit. While no video signal is applied in the case that the video signal is intermittently read, the LCD drive circuit suspends applying of drive pulses to the LCD and maintains a currently-displayed image on the LCD. On the other hand, while no image data is read from the image memory in the case that the image data is intermittently read from the image memory for the display on the LCD, the image memory can be freely accessed to perform other signal processing such as recording the image data into an external storage medium.
