A projection display apparatus includes an imager that modulates light emitted from a light source and a projection unit that projects light emitted from the imager on a projection surface. The projection display apparatus includes: an imager controller that controls the imager to display a test pattern image in which a characteristic point is defined by at least three adjacent regions; an acquisition unit that acquires a captured image of the test pattern image from an imaging element configured to capture the test pattern image projected on the projection surface; and an adjustment unit that identifies the characteristic point included in the captured image on the basis of the captured image acquired by the acquisition unit and adjusts an image to be projected on the projection surface on the basis of the identified characteristic point. The at least three adjacent regions surround the characteristic point and are adjacent to the characteristic point.

Projection display apparatus

A projection display apparatus includes: a light amount sensor which detects an amount of light emitted from an array light source; a deterioration rate calculator which acquires an amount of light of a measurement target light source from the amount of light detected by the light amount sensor; a reference light amount storage which stores a reference amount of light of an amount of light emitted from plurality of solid state light sources, for each of the solid state light sources; and a light source controller which controls the amount of light emitted from the plurality of solid state light sources for each of the solid state light sources, and the deterioration rate calculator determines whether the measurement target light source has deteriorated, in accordance with a result of a comparison between the amount of light detected by the light amount sensor, and the reference amount of light.

An image signal processor includes a controller configured to generate a red output signal, a green output signal, a blue output signal and a fourth color output signal in accordance with image input signals. A fourth color light component enables to reproduce a color outside the range of a color reproducible by the red light component, the green light component and the blue light component. The controller generates the fourth color output signal on the basis of a reference signal corresponding to a color different from a complementary color of a color reproduced by the fourth color light component.

Image signal processor and image display device

An illumination apparatus includes: a solid-state light source; a Peltier element configured to cool the solid-state light source; a light amount sensor configured to detect an amount of a light emitted from the solid-state light source; a power consumption monitor configured to monitor power consumptions of the solid-state light source and the Peltier element; and a power controller configured to control powers supplied to the solid-state light source and the Peltier element. The power controller controls the powers supplied to the solid-state light source and the Peltier element, on the basis of the light amount detected by the light amount sensor and a sum of the power consumptions of the solid-state light source and the Peltier element.

In a captured image outputting system, an image shot by an image capturing device is, upon shooting the image thereby, instantaneously transmitted to a display control device of a display system via wireless communication. The display system instantaneously projects the received image on a projection screen. The display system is comprised of a display device and a display control device. A liquid crystal projector may serve as the display device whereas an optional device, for use in wireless communication, connected to image input terminals of the liquid crystal projector may serve as the display control device. A digital still camera may serve as the image capturing device capable of carrying out wireless communication.

Digital cameras which improve operability in checking, storing, and editing shot images have not been satisfactory. A digital camera and a user terminal including a file server are connected over a network. When the digital camera is powered on, it automatically establishes a network connection with the file server in an activation process. When the digital camera shoots an image, this image is transmitted to the file server automatically upon completion of the encoding and compression of the image. When image reproduction is instructed from the digital camera, the image is downloaded from the file sever over the network and displayed on the digital camera.
