are acquired by said at least one control circuit respectively correspond to the plurality of segmented areas, and

wherein said at least one control circuit performs, controlling respective charge accumulation periods for each of the segmented
areas corresponding to the plurality of areas in the image capturing area based on the respective information corresponding
to the distances to the objects in the corresponding segmented areas.

BLOCK PATTERNS AS TWO-DIMENSIONAL RULER

Canon Kabushiki Kaisha, ...

1. A computer-implemented method of determining a two-dimensional position of a location captured in an image, said method
comprising:
forming a two-dimensional greyscale pattern, said two-dimensional pattern comprising a plurality of R-planes, wherein each
said R-plane comprises a tiling of a corresponding R-ary block, being a block of radix R integer values, such that for each
dimension of the pattern, the least common multiple of each of the sizes of said corresponding tiled R-ary blocks in that
dimension is greater than the size of the pattern in the same dimension, and such that any R-ary sub-block of a predetermined
size less than the tiled R-ary blocks occurs only on a regular grid with the same periodicity as the tiled R-ary block for
that R-plane;

imparting the two-dimensional pattern onto a scene;
capturing an image of the scene including the projected two-dimensional pattern;
determining from the captured image a sub-block associated with the location and constructing, from a R-ary representation
of the sub-block, a unique integer value for each R-plane, being a representation of the pattern in the R-plane of the sub-block
associated with the location; and

using said unique integer values from each R-plane to determine the location in the image.

OPHTHALMOLOGIC APPARATUS, AND OPHTHALMOLOGIC METHOD AND PROGRAM

Canon Kabushiki Kaisha, ...

1. An ophthalmologic apparatus comprising:
a measuring unit which measures information of an eye to be inspected by illuminating the eye to be inspected;
a driving unit which drives the measuring unit;
a transillumination moving image acquiring unit which acquires a transillumination moving image of the eye to be inspected;
a display control unit which controls a display unit to display the transillumination moving image;
a changing unit which changes a reference position for performing alignment between the eye to be inspected and the measuring
unit in the transillumination moving image displayed on the display unit; and

a control unit which controls the driving unit so as to perform the alignment by using the changed reference position.

IMAGE HEATING APPARATUS

Canon Kabushiki Kaisha, ...

1. An image heating apparatus comprising:
a rotatable heating member configured to heat a toner image formed on a recording material by using a toner containing a parting
agent;

an exciting coil provided outside said rotatable heating member and configured to cause said rotatable heating member to generate
heat by electromagnetic induction heating;

a magnetic flux suppressing member configured to suppress a part of magnetic flux acting from said exciting coil onto said
rotatable heating member in a longitudinal direction of said rotatable heating member;

a moving mechanism configured to move said magnetic flux suppressing member between said exciting coil and said rotatable
heating member depending on the width size of the recording material;

a motor configured to drive said moving mechanism; and
an executing portion capable of selectively executing an operation in a first mode in which a first current is supplied to
said motor and an operation in a second mode in which a second current larger than the first current is supplied to said motor.

VIDEO DISPLAY APPARATUS, VIDEO PLAYBACK APPARATUS AND METHOD FOR CONTROLLING THE SAME

Canon Kabushiki Kaisha, ...

1. A device comprising:
a receiving unit that receives a playback request for requesting a trick playback;
a reproducing unit that reproduces predetermined video if the playback request is received by the receiving unit;
a first changing unit that performs a first process for changing a number of frames included in the predetermined video;
a transmitting unit that transmits video to an external display device, wherein the external display device includes a second
changing unit that performs a second process for changing a number of frames included in video which is received from the
transmitting unit; and

a control unit that (a) selects, according to a capability of the first changing unit and a capability of the second changing
unit, at least one of the first changing unit and the second changing unit after the playback request is received by the receiving
unit, and (b) causes a selected changing unit to perform a process for changing a number of frames included in video to generate
video requested by the playback request.

SYSTEMS AND METHODS FOR COMPARING IMAGES

Canon Kabushiki Kaisha, ...

1. An image similarity scoring method comprising:
counting a number of matching visual words between a query image and a candidate image, wherein each matching visual word
is found in both the query image and the candidate image;

generating an image similarity score for the query image and the candidate image based at least in part on the counted number
of matching visual words; and

generating a normalized image similarity score based at least in part on the image similarity score and one or more of a complexity
of the query image and a complexity of the candidate image, wherein the normalized image similarity score is generated according
to a weighting function that is described by a finite unimodal function.
