    Abstract: A decorative sheet comprises a substrate layer; a pattern layer provided on the first front surface of the substrate layer; and a thermoplastic resin layer provided on the second front surface of the pattern layer. A test piece of 8 mm width from the decorative sheet is taken; the storage modulus is measured with an initial chuck distance of 10.77 mm, a start temperature of 30° C., an end temperature of 150° C., a temperature increase rate of 5° C./min, and a measurement frequency of 1.0 Hz. The ratio of the difference between the second storage modulus and a third storage modulus when the decorative sheet changes from the transition region to a rubbery flat region to the difference between a first storage modulus when the environmental temperature is 30° C. and a second storage modulus when the decorative sheet changes from a glassy region to a transition region is 3.5 or less.

    IPC: H04N25/705

    CPC classification number: H04N25/705

    Abstract: A range imaging device includes a light source unit, a light-receiving unit that includes pixel driving circuit and a pixel including a photoelectric conversion element and charge storage units, a storage unit that stores table information in which electric charge ratios are associated with corresponding distances to an object, and a range image processing unit that determines a measured distance to an object using the table information and the amounts of electric charge accumulated in the charge storage units. The range image processing unit calculates the electric charge ratio based on the amounts of electric charge accumulated in the charge storage units, acquires the corresponding distance associated with the calculated electric charge ratio from the table information, and determines the measured distance using the acquired corresponding distance.

    Abstract: A range imaging device includes a light-receiving unit including at least one pixel circuit including a photoelectric conversion element that generates charge in response to incident light, N (N≥3) charge storage units that integrate charge in a frame cycle, and transfer transistors, and a pixel drive circuit that causes the transfer transistors to distribute charge to the charge storage units with integration timing synchronizing with light pulses, a light source unit that emits light pulses; a range image processing unit that calculates a distance to an object based on integrated charges, and a measurement control unit that calculates a thinning time of not integrating charge, according to integrated charge in the charge storage units, the distance, and intensity of the incident light. The measurement control unit controls integration of charge with a thinning time set in a measurement zone corresponding to the distance from the light-receiving unit.

The control unit decrements the time by a first unit until the integrated charge becomes equal to or smaller than a first threshold.
