Portable terminal device, program, device shake compensation method, and condition detection method
First Claim
1. A portable terminal device operable by an operator, the portable terminal device comprising:
- circuitry configured to;
acquire image data by capturing surroundings in capturing periods of a predetermined length, whereinthe image data includes first image data and second image data,the first image data is acquired in a first capturing period,the second image data is acquired in a second capturing period, andthe first capturing period is a former period to the second capturing period;
generate face data and detection object data from the second image data, the face data representing a face of the operator and articles worn by the operator, and the detection object data being obtained by excluding the face data from the second image data and representing a remaining portion of the second image data other than the face data;
detect a motion of an object in the second image data based on the detection object data by comparing the detection object data with a former detection object data, the object being included in the detection object data, the motion of the object indicating a positional change of pixels representing the object in the detection object data, and the former detection object data being generated from the first image data acquired at the first capturing period; and
determine a condition of the operator in accordance with the motion of the object.

Abstract
A portable terminal device operable by an operator is provided with a display unit which displays display data, an image capturing unit and an image signal processing unit which acquire image data containing the face of the operator, a detection unit which detects a relative positional change between the display data displayed on the display unit and the face of the operator based on the acquired image data to create change data, a determination unit which determines whether or not the operator is walking, and a display control unit which, in a case where the determination unit has determined that the operator is walking, controls a displaying position in the display unit of the display data displayed on the display unit so that the relative positional change detected by the detection unit is suppressed.

8. A condition detection method for detecting a condition of a portable terminal device including circuitry, the condition detection method comprising:
-
acquiring, by the circuitry, image data by capturing surroundings in capturing periods of a predetermined length, wherein the image data includes first image data and second image data, the first image data is acquired in a first capturing period, the second image data is acquired in a second capturing period, and the first capturing period is a former period to the second capturing period; generating, by the circuitry, face data and detection object data from the second image data, the face data representing a face of an operator and articles worn by the operator, and the detection object data being obtained by excluding the face data from the second image data and representing a remaining portion of the second image data other than the face data; detecting, by the circuitry, a motion of an object in the second image data based on the detection object data by comparing the detection object data with a former detection object data, the object being included in the detection object data, the motion of the object indicating a positional change of pixels representing the object in the detection object data, and the former detection object data being generated from the first image data acquired at the first capturing period; and determining, by the circuitry, a condition of the operator in accordance with the detected motion of the object.
