摘要： A projecting unit projects a focus adjustment pattern onto a screen. An image capturing unit captures an image of the focus adjustment pattern and obtains the image as a captured image. A captured image analyzing unit calculates contrast data serving as an evaluation value indicating a degree of achievement in focusing the captured image. Based on the calculated contrast data, a control unit adjusts focus of the projecting unit so as to bring projected image light into a focus on the projection surface. The focus adjustment pattern has a first region and a second region different from each other in brightness. The control unit adjusts configurations of the first region and the second region in the focus adjustment pattern such that at least one of resolution of brightness and contrast becomes uniform in the captured image.

摘要： A projection unit projects a predetermined image onto a projection plane through a lens. An image generating unit generates the predetermined image which is to be projected from the projection unit. A code generator generates a notifying image that contains information to be conveyed to another projector provided with an image pickup function. The projection unit projects the notifying image generated by the code generator and has the another projector capture the notifying image so as to convey the information to the another projector.

摘要： A projection-type image display apparatus projects an image on a projection plane, and includes a projection unit, an image capture unit, an ambient light detection unit, and a superimposed image generation unit. The projection unit projects an image on the projection plane through a lens. The image capture unit captures the image projected on the projection plane by the projection unit. The ambient light detection unit detects ambient light cast on the projection plane, from the image captured by the image capture unit. The superimposed image generation unit generates information about detection of ambient light detected by the ambient light detection unit, in the form of a superimposed image to be superimposed on the image projected on the projection plane.

摘要： A focus evaluation value calculation unit acquires a captured image captured by an image capturing unit and then analyzes the image so as to calculate, as a focus evaluation value, a characteristic value that changes in accordance with the focus state of a video image adjusted by a focus adjustment unit. A focus evaluation value storage unit stores the focus evaluation value and a target value of a focus evaluation value. A focus state determination unit determines a display color of focus state information, which is shown as a graph with a color indicating the degree of focus. The focus state determination unit includes: a unit for calculating a change of the focus evaluation value; and a unit for determining the focus state information to be displayed by referring to a table that associates a combination of the change of the focus evaluation value, the focus evaluation value, and the target value with the display color of the focus state information.
