A projection apparatus according to the present invention, includes: a field programmable gate array (FPGA) configured to control projection; and at least one processor which functions as: a configuration unit configured to configure a circuit to be included in the FPGA to a circuit corresponding to a state of the projection apparatus.

Projection apparatus and control method thereof

An image display apparatus according to the present invention includes: a display unit configured to display a moving image based on input moving image data; a determining unit configured to determine whether or not a specific reproduction operation related to a reproduction method of the moving image data has been performed; and a control unit configured to control display by the display unit so that display of a moving image of which brightness is higher than a first threshold is suppressed in a case where the specific reproduction operation has been performed.

Image display apparatus, image output apparatus, and control methods thereof

An information processing apparatus according to the present invention, includes: a first acquiring unit configured to acquire surface change information on magnitude of change of a projection surface onto which an image is projected; and a determining unit configured to determine, based on the surface change information, frame rate control information on a frame rate of image processing to allow the image to follow the projection surface.

Controlling projected image frame rate in response to determined projection surface curvature

An image processing apparatus according to the present invention, includes: a determination unit configured to determine, based on a layout of at least one image included in display image data, a display correspondence, which is a correspondence between a gradation value of the display image data and a display brightness in a case where a display unit displays an image based on the display image data; and an output unit configured to output to the display unit the display image data and information indicating the display correspondence.

Image processing apparatus and image processing method

An image processing apparatus comprises: a first generation unit that generates approximate light pattern by adjusting spatial frequency of an input image, and generates a projection image data based on the approximate light pattern; and a second generation unit that generates a print image data based on the input image, wherein the second generation unit generates the print image data so that a difference between the input image and an image for observation obtained by superimposing projection light projected based on the projection image data onto a printed matter printed based on the print image data is reduced.

To more flexibly reproduce moving image data obtained by capturing a plurality of frames within the period of a single frame of display output while changing the exposure condition. For example, moving image data, which has been obtained by capturing a plurality of frames within the period of a single frame of display output while changing the exposure condition, is stored in a recording portion. When the moving image data is reproduced from the recording portion, a single frame is selected and output by a reproduced frame selecting portion for each period of a single frame of display output. If a user operation instructing to make the displayed image darker, in response to this user operation, a frame having an exposure condition of underexposure is selected and output from the moving image data to be reproduced from the recording portion for each period of a single frame of display output.

Reproducing apparatus and reproducing method

An image processing apparatus according to the present invention, comprises:

An image processing apparatus includes a histogram creation unit that creates a histogram from an input image, a detection unit that detects a gradation level of interest from the histogram, a gradation correction parameter generation unit that generates a gradation correction parameter to improve a gradation characteristic in a gradation range around the gradation level of interest, and a correction unit that corrects the gradation of the image using the gradation correction parameter. The detection unit detects, as the gradation level of interest, a gradation level whose frequency is a peak value equal to or more than a predetermined threshold, and which has variation width of frequencies in a predetermined range including this gradation level to be smaller than a predetermined width in the histogram.

Image processing apparatus and control method thereof detecting from a histogram a gradation level whose frequency is a peak value

Moving image data, obtained by capturing a plurality of frames within the period of a single frame of display output while changing the exposure condition, can be more flexibly produced. For example, such moving image data is stored in a recording portion. When the moving image data is reproduced from the recording portion, a single frame is selected and output by a reproduced frame selecting portion for each period of a single frame of display output. In response to a user operation instructing to make the displayed image darker, a frame having an exposure condition of underexposure is selected and output from the moving image data to be reproduced from the recording portion for each period of a single frame of display output.

An image recording and reproducing apparatus that records and reproduces image data shot at a frame rate higher than a normal reproduction rate employed during reproduction of a moving image can generate a still image by attaching still image recording information to at least one frame image included in the recorded image data and combining a plurality of frame images of the recorded image data in accordance with the still image recording information.

Image recording and reproducing apparatus

There is provided a communication apparatus that includes: a data communication unit which performs half-duplex communication of video frame data with an external device on a video frame-by-video frame basis, a switching unit which switches a transmission direction in which the data communication unit transmits the video frame data, a first control unit which controls the data communication unit to include a start command in the video frame data and send the video frame data, as well as controls the switching unit to switch the transmission direction in response to completion of the sending of the video frame data that includes the start command, and a second control unit which controls the switching unit to switch the transmission direction in response to completion of the reception of the video frame data that includes the start command.
