ELECTRONIC CAMERA APPARATUS CAPABLE OF PROVIDING WIDE DYNAMIC RANGE IMAGE SIGNAL |
摘要 |
An electronic camera apparatus provides an image pickup signal to serve an image display by an image monitor. An image pickup section has at least a solid-state image pickup element and generates an image signal by electrically picking up an image of a target object to be photographed. A control section time-divisionally and repeatedly executes image pickup processing of the target object a plurality of times by using the image pickup section and a read operation of the image signal obtained by the image pickup processing. An accumulative addition section sequentially performs accumulative addition of the image signals repeatedly read from the image pickup section by the control section. A processing section processes the image signal obtained by the accumulative addition section upon sequential, accumulative addition so as to allow the image signal to be used for an image display by the image monitor.
