Abstract
Abstract An illumination measuring device for panoramic picture taking has a first photoelectric illumination intensity receiver which diffusely determines light falling in a first measuring region and illuminating a first panoramic portion, at least one further photoelectric illumination intensity receiver which diffusely determines light falling in a second measuring region and illuminating a further panoramic portion, and an evaluating unit determining a deviation of an illumination intensity determined by the further illumination intensity receiver from an illumination intensity determined by the first illumination intensity receiver.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
84 words
An illumination measuring device for panoramic picture taking, comprising a first photoelectric illumination intensity receiver which diffusely determines light falling in a first measuring region and illuminating a first panoramic portion; at least one further photoelectric illumination intensity receiver which diffusely determines light falling in a second measuring region and illuminating a further panoramic portion; and an evaluating unit determining a deviation of an illumination intensity determined by said further illumination intensity receiver from an illumination intensity determined by said first illumination intensity receiver.
Claim 2
Dependent Claim
84 words
An illumination measuring device for panoramic picture taking, comprising a first photoelectric illumination intensity receiver which diffusely determines light falling in a first measuring region and illuminating a first panoramic portion; at least one further photoelectric illumination intensity receiver which diffusely determines light falling in a second measuring region and illuminating a further panoramic portion; and an evaluating unit determining a deviation of an illumination intensity determined by said further illumination intensity receiver from an illumination intensity determined by said first illumination intensity receiver.
Claim 3
Dependent Claim
24 words
An illumination measuring device as defined in claim 1; and further comprising an indicating unit for representing said deviation determined by said evaluating unit.
Claim 4
Dependent Claim
25 words
An illumination measuring device as defined in claim 1; and further comprising a torus-shaped curved diffuser, said illumination intensity receiver being arranged behind said diffuser.
Claim 5
Dependent Claim
21 words
An illumination measuring device as defined in claim 1; and further comprising a light screen located between said illumination intensity receivers.
Claim 6
Dependent Claim
39 words
An illumination measuring device as defined in claim 1; and further comprising a control circuit connected with said evaluating unit and operative for changing a turning speed of an objective of a panoramic camera during the panoramic picture taking.
Claim 7
Dependent Claim
40 words
An illumination measuring device as defined in claim 1; and further comprising a control circuit connected with said evaluating unit and operative for changing an opening of a shutter of an objective of a panoramic camera during panoramic picture taking.
Claim 8
Dependent Claim
53 words
An illumination measuring device as defined in claim 1; and further comprising a photoelectric light density receiver adapted to face a panorama object opposite to said photoelectric illumination intensity receivers, said light density receiver being also influenced by changing a turning speed of an objective of a panoramic camera during panoramic picture taking.
Claim 9
Dependent Claim
63 words
An illumination measuring device as defined in claim 1; and further comprising a photoelectric light density receiver adapted to face a panorama object opposite to said photoelectric illumination intensity receivers, said light density receiver influenced by changing an opening of an objective of a panoramic camera and changing of an opening of an objective shutter of the panoramic camera during panoramic picture taking.
Claim 10
Dependent Claim
28 words
An illumination measuring device as defined in claim 1; and further comprising a housing; and an accessory shoe arranged on said housing for coupling with a panoramic camera.
Claim 11
Dependent Claim
22 words
An illumination measuring device as defined in claim 9, wherein said accessory shoe has transmission contacts electrically connected with said evaluating unit.
Claim 12
Dependent Claim
49 words
An illumination measuring device as defined in claim 9, wherein said accessory shoe is turnable about an axis which is adapted to extend parallel to a turning axis of an objective of a panoramic camera when the illumination measuring device and the panoramic camera are coupled with one another.
Claim 13
Dependent Claim
57 words
An illumination measuring device as defined in claim 3, wherein said diffuser is arranged so that when the illumination measuring device is coupled with a panoramic camera said diffuser is lifted relative to said illumination intensity receivers from a plane extending parallel to a turning plane of an objective of the panoramic camera about an inclination angle.
Claim 14
Dependent Claim
36 words
An illumination measuring device as defined in claim 12, wherein said housing has an accessory shoe for coupling to the panoramic camera, said accessory shoe being arranged tiltably parallel to a plane of said inclination angle.
Claim 15
Dependent Claim
30 words
An illumination measuring device as defined in claim 1; and further comprising a change-over switch associated with said evaluating unit for changing the determined deviation to provide a plus-minus reverse.
Claim 16
Dependent Claim
48 words
An illumination measuring device as defined in claim 14; and further comprising a position detector which recognizes horizontal or vertical holding of the panoramic camera or the illumination measuring device corresponding to wide format and high format panoramic picture taking so as to correspondingly actuate said change-over switch.
