An image processing apparatus includes a first color gamut conversion unit that converts an input image signal in an XYZ color system into an output image signal in a linear RGB color system by using the inverse matrix of a matrix including, as its components, values obtained by normalizing XYZ values by a predetermined luminance value, the XYZ values being obtained by measuring an image for measurement displayed in a display device for which a determination is made, and a determination unit that determines, when an R, G, or B value of the output image signal is larger than a first predetermined value, that the display device cannot display an image related to the input image signal with brightness corresponding to respective luminance of the input image signal.

A detection apparatus includes a display (101), an imaging unit (102) an eye gaze detector (354), an output controller (356), and a gaze point detector (355). The imaging unit (102) images a subject. The eye gaze detector (354) detects an eye gaze direction of the subject based on a captured image captured by the imaging unit (102). The output controller (356) displays a diagnostic image that includes an own person image including a face image and a geometric pattern image, onto the display (101). The gaze point detector (355) detects a first gaze point as a gaze point of the subject in the person image based on the eye gaze direction and detects a second gaze point as a gaze point of the subject in a region that includes at least one of a center of a geometric pattern, a characteristic portion of the geometric pattern, a portion in which density of lines forming the geometric pattern is higher than other portions, and a portion in which the geometric pattern changes, in the geometric pattern image.


An image display apparatus (100 or 800) includes a laser light source unit (164), a scan mirror unit (170), a rendering control unit (132), a detecting unit (122 or 145), and an output adjusting control unit (134). The rendering control unit (132) controls the laser light source unit (164) in such a way that a display image is rendered in a range smaller than a scan range of the scan mirror unit (170) based on input display image data. The detection unit (122 or 145) detects a range to be a reference for setting a laser beam output position for adjusting an output of the laser beams based on the display image data. The output adjusting control unit (134) controls the laser light source unit (164) in such a way that the laser beams for adjusting an output of the laser beams are output at a position outside the range where the display image is rendered in the scan range of the scan mirror unit (170), and the position is based on the range detected by the detecting unit (122 or 145).

A scanning mirror unit (13) two-dimensionally scans with infrared laser light emitted from a first light source unit (Dir), visible laser light emitted from a second light source unit (Db, Dg, Dr), or laser light in which both the laser light are superimposed on each other. A reflected light detection unit (PD2) detects reflected light of infrared laser light emitted via the scanning mirror unit (13). An object recognition unit (22) recognizes an object present within the emission range (2) of infrared laser light based on the reflected light detected by the reflected light detection unit (PD2). When an object is recognized by the object recognition unit (22), the second light source unit (Db, Dg, Dr) emits visible laser light, which is different in accordance with information on the object, toward the object, a neighborhood of the object, or both the object and the neighborhood thereof.

An image display device (100) includes: an RGB laser diode (200) configured to output laser light; a horizontal scanner (220) configured to reflect the laser light and perform a reciprocating operation in a horizontal direction; a scanning detection unit (202) configured to detect a forward or reverse operation range and a reciprocating operation range in each line in the horizontal direction; a drawing position control unit (116) configured to determine an image display position in each line based on a difference between the detected operation ranges and a reference value; and a laser driver (140) configured to drive the RGB laser diode (200) based on image data at a timing corresponding to the determined image display position.


A mobile communication unit 30 performs communication using a first communication scheme. A business wireless communication unit 32 performs communication using a second communication scheme different from the first communication scheme. A storage unit 44 stores first information and second information, mapping the first information and the second information to each other, the first information being defined to receive, using the first communication scheme, service from a further communication terminal device capable of communication using the first communication scheme and the second communication scheme, and the second information being defied to perform communication with the further communication terminal device using the second communication scheme. A business wireless processing unit 302 causes communication based on the second information stored in the storage unit 44 to be performed preferentially, when the business wireless communication unit 32 performs communication with the further communication terminal device while the mobile communication unit 30 is receiving the service from the further communication terminal device.
