发明名称 An aspect conversion circuit used in a camera apparatus
摘要 A camera apparatus in which a video camera and a photographic camera are integrally combined or which has a self-timer function, and an aspect conversion circuit for converting the orientation of an image are provided. A normal mode and a self-timer mode are provided, and in either mode, a shutter pulse synchronized with a vertical synchronizing signal is obtained from an output signal of a frequency divider, while in the self-timer mode, a timer is driven by the output signal of the frequency divider, whereby the frequency divider is used in both modes. Alternatively, a still mode and a video mode is provided, and in the still mode, a shutter pulse and a record pulse are output in response to an operation of a shutter switch, while in the video mode, the record pulse is output in response to an operation of a record switch and the shutter pulse is output in response to an operation of the shutter switch. Furthermore, a field memory or a frame memory is arranged in the aspect conversion circuit, and a write direction with respect to the memory is made different from a read direction, to thereby obtain an aspect-converted video signal. <IMAGE>
