Abstract
A photographic device typically employing a CCD element as a shutter is arranged to have an improved display system. The display system displays the picture number per unit time and the image information storage time by using different display conditions so as to avoid confusion as to what is being displayed. The device enables the photographing picture number per unit time to be taken as a multiple series of 2, such as 60, 30, 15, 8, 4, 2 1 . . . , pictures/second in order to make the numerical series of the photographing picture number common with that for the storage time of the image information so that the image information storage time and the photographing picture number per unit time can be displayed with a common display means.
Claims26
An image pick-up device comprising:
- (a) image pick-up means for converting an optical picture information into an electrical signal;
- and
- (b) picture number designating means for selectively designating a number of picture pick-ups per unit time in the image pick-up means out of a plural number of set values, whereby the plural number of set values is in the relation satisfying about 2.sup.n, (n:
- an integer).
An image pick-up device, comprising:
- (a) image pick-up means for converting an optical picture information into an electrical signal;
- (b) image pick-up period designating means for selectively designating the image pick-up period of the optical picture information in the image pick-up means out of a plural number of set values;
- (c) picture number designating means for selectively designating a number of picture pick-ups per unit time in the image pick-up means out of a plural number of set values;
- and
- (d) control means for controlling a pick-up period in the image pick-up means in response to an output of said image pick-up period designating means,
- whereby the plural number of set values concerning the image pick-up period and that concerning the picture number are both included in a numerical series of about m.sup.n (m:
- a predetermined common constant value, n:
- an integer).
A picture pick-up device, comprising:
- (a) image pick-up means for storing an optical picture information;
- (b) image pick-up period designating means for selectively designating an image pick-up period of the optical picture information out of a plural number of set values;
- (c) a picture number designating means for selectively designating a number of picture pick-ups per unit time in the image pick-up means out of a plural number of set values;
- and
- (d) control means for controlling a pick-up period in the image pick-up means in response to an output of said image pick-up period designating means,
- whereby the plural number of set values concerning the picture number are involved in the plural number of set values concerning the image pick-up period or the reciprocals thereof.
An image pick-up device comprising:
- image pick-up means for converting an optical picture information into an electrical signal;
- record means for recording said electrical signal;
- and
- picture number designating means for selectively designating numbers of pictures recorded per unit time out of a plural number of set values, whereby the plural number of set values is in the relation satisfying about 2.sup.n, (n:
- an integer).
