Abstract: An image sensing apparatus having a diaphragm of a normally closed type for controlling the entrance of light into an image sensor. The diaphragm is opened from a fully closed state to a predetermined aperture value based on the output of a light measuring element other than the image sensor and is closed again when a first exposure operation is carried out, and then it is opened from the fully closed state to another predetermined aperture value which is based on the signal formed by the image sensor during the first exposure operation and is closed again when a second exposure operation is carried out. An electrical signal formed by the image sensor during the second exposure operation is recorded as a still picture signal, thus giving an advantage that the aging change of the diaphragm and the tolerance of the exposure can be canceled.

Abstract: A video recording camera having a movable head and actuating apparatus for controlling an exposing state of an image pick-up apparatus, wherein the internal structural arrangement of the camera is simplified for a head shifting apparatus and for a charging apparatus which accumulates an urging force for the actuating apparatus. This arrangement results in a reduction in size of the video recording camera. This arrangement enables a successive shot function in addition to a single shot function, and causes the head to shift to a position on a recording medium coinciding with a position indicated by an indicating member on the recording medium container while inhibiting power from being supplied to other operating systems of the camera until the coincidence is achieved.
