The present disclosure provides a floating touch camera module, a display device and a touch method. The floating touch camera module includes: a lens with a light collection surface and a light emitting surface; an image sensor at one side of the light emitting surface of the lens, the image sensor configured to receive light rays from the lens and form sensing information; and an infrared cut filter film at one side of a light incident surface of the image sensor and configured to filter out infrared light rays. The infrared cut filter film is movable relative to the lens between a first position at which the infrared cut filter film directly faces the lens and a second position at which the infrared cut filter film is offset from the lens, thereby enabling the floating touch camera module to switch between a photographing mode and a touch mode.

An information processing device includes: an acquisition unit and an association unit. The acquisition unit acquires first information, generated by processing a detection result which is output from a first sensor provided outside an electronic writing instrument, which includes a trajectory traced by the electronic writing instrument in writing of an object on a display image and second information, generated by processing a detection result which is output from a second sensor provided in the electronic writing instrument to detect a movement of the electronic writing instrument, which includes a trajectory traced by the electronic writing instrument in writing of the object on the display image. The association unit associates the object with the electronic writing instrument using the first information and the second information.

A method of controlling a projector includes projecting an achromatic area image representing a drawing area in which the projector receives drawing using a pointer on a projection surface at a first luminance at a ratio on the projection surface, the ratio being smaller than or equal to a specific ratio to a maximum luminance at which the projector capable of project an image on the projection surface, detecting a position on the projection surface pointed by the pointer while projecting the area image, determining whether or not the position is included in the drawing area, and displaying, by the projector, an area including at least a part of an outline of the drawing area at a luminance higher than the first luminance when it is determined that the position is included in the drawing area.

Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction. Additionally, an energy detection receiver for IR-UWB is presented to similarly meet these design goals whilst being adaptable to address IR-UWB transmitter specificity.

A light outputting apparatus includes a light source that outputs a first light flux, a collimator that parallelizes the first light flux, a light separator that separates the first light flux into a first partial light flux and a second partial light flux, a first light flux width expander, and a second light flux width expander. The light separator causes the first partial light flux to exit in a first direction and the second partial light flux to exit in a second direction. When a first plane is assumed to be a plane containing the first direction and the second direction, the first light flux width expander expands a width of the first partial light flux in a direction along the first plane, and the second light flux width expander expands a width of the second partial light flux in a direction along the first plane.

An electronic watch includes a housing defining a side surface of the electronic watch, a transparent cover coupled to the housing and defining a front surface of the electronic watch, an image-sensing element, and a crown extending from the side of the housing and defining an imaging surface. The crown may include a light-directing feature configured to direct, onto the image-sensing element, an image of an object in contact with the imaging surface.

[Problem] An information processing apparatus, an information processing method, and a recording medium with which a user can recognize a boundary of a drivable range by feedback for a projection specification position by the user to facilitate determination of and search for a projection position are provided. [Solution] The information processing apparatus includes a controller configured to perform processing of outputting feedback indicating an effect corresponding to a boundary of a drivable region of a drive-type projector in a projection environment space in accordance with a state of a projection specification position specified by a user for the drivable region, the state being determined based on the drivable region and the projection specification position.

In a case where a second camera operation through a third input unit using an inertial sensor is performed while a pointer operation process based on a pointer operation through a first input unit or a camera operation process based on a first camera operation through a second input unit is performed, an absolute value of a quantity of change in a position or an image capturing direction of a virtual camera based on the second camera operation is reduced as compared with a case where the second camera operation is performed when neither of the pointer operation process based on the pointer operation and the camera operation process based on the first camera operation are performed.

Provided are an imaging apparatus, an imaging method, and a program capable of accurately and simply controlling a movement sensitivity of an index displayed on a finder monitor to a sensitivity desired by a user by using a touch panel installed on a rear monitor. The imaging apparatus (10) has a finder that includes the finder monitor (13), the touch panel (31) that receives a swipe operation for moving the index, and an image processing unit (24). The image processing unit (24) includes a sensitivity setting unit that sets a first sensitivity for coarsely moving the index by the swipe operation or a second sensitivity for finely moving the index by detecting a contact operation to the touch panel in the swipe operation, and a movement control unit that moves the index on the basis of the swipe operation on the touch panel and the sensitivity set by the sensitivity setting unit.
