One or more projection apparatuses, control methods for one or more projection apparatuses, and storage mediums for use therewith are provided herein. At least one projection apparatus includes: a projection unit including an optical unit, the projection unit being configured to project a projection image including a predetermined display item onto a projection surface; a sensor configured to sense a predetermined area corresponding to the predetermined display item on the projection surface; and a control unit configured to: (i) perform predetermined processing relating to the projection image in response to the sensor detecting a predetermined instruction in the predetermined area, and (ii) stop sensing performed by the sensor in a case where a state of the optical system of the projection unit changes while the projection image including the predetermined display item is being projected.

Projection apparatus, method for controlling projection apparatus, and non-transitory storage medium

A projection apparatus, comprises a projection unit configured to project an image onto a screen including a target image, a switching unit configured to switch to one of a first image for indicating a position deviation between a projection area in which the projection unit projects an image and the target image, and a second image for increasing contrast of the target image, and a control unit configured to control the projection unit so as to project an image in the projection area based on an image to which the switching unit has switched, wherein the first image is an image that has a predetermined relationship with colors of the target image.

Projection apparatus, information processing apparatus, and control methods thereof

Each projection apparatus in a multi-projection system has a liquid crystal panel, a driving circuit configured to perform PWM control of the liquid crystal panel, and a projection image processing unit configured to perform edge blending processing to perform compositing display by each projection apparatus and processing to change gain properties of the edge blending processing by each projection apparatus. Synchronization of each projection apparatus is maintained by a synchronization circuit. Therefore, a sum of image gain in a region of image compositing by each projection apparatus is 1, and the position and image gain properties of the compositing region are changed for each frame, so the position of image deterioration changes for each frame.

Projection apparatus, method of controlling projection apparatus, and projection system

A display apparatus includes a display unit that displays a first image on a screen, wherein the first image includes a first area and a second area, wherein the first area is an area in which an image displayed by another display apparatus is superimposed, and wherein the second area is an area in which a second image is displayed, and a control unit that controls a position of the second area so that at least a part of the second area and at least a part of the first area are not superimposed on each other if a request for changing a position of the second area so that at least a part of the second area and at least a part of the first area are superimposed is input.

Display apparatus for performing control to change a position on an image where an additional image is superimposed

Based on image data input to a display unit and an image on a display surface acquired by an acquisition unit, control is performed to decrease the difference between the input image data and the image displayed on the display surface.

Image display apparatus, information processing apparatus, and methods of controlling the same

An image capture apparatus includes an image capture unit, a recording unit, a wireless communication unit and a control unit. The recording unit records digital image captured by the image capture unit on a recording medium. The wireless communication unit transmits the digital image recorded on the recording medium to an external recording apparatus. The control unit determines, using additional information corresponding to the digital image recorded on the recording medium, whether or not the digital image recorded on the recording medium is already transmitted to the external recording apparatus. The additional information is received from the external recording apparatus. The control unit controls the wireless communication unit to transmit the digital image recorded on the recording medium to the external recording apparatus if the control unit determines that the digital image recorded on the recording medium is not already transmitted to the external recording apparatus.

Image communication apparatus for wireless communication of digital images, and method thereof

In an image sensing apparatus which performs noise reduction processing using pixel signals obtained by consecutively scanning a CCD image sensor at different timings, for performing image expansion in the vertical direction by controlling scanning of the CCD image sensor, an area to be read in the CCD image sensor is set on the basis of an expansion ratio. Pixel signal which have undergone the noise reduction processing and stored in advance in a memory are read so that colors of corresponding pixel signals do not shift. The noise reduction processing is performed on the current pixel signals read from the set area using the pixel signals read from the memory. The noise-reduced pixel signals are stored in the memory, and used in the next noise reduction processing for pixel signals read from the CCD image sensor of the next period.

Image sensing apparatus and method having noise reduction function

There is disclosed an image pickup apparatus which outputs moving image information, obtained with an image pickup device of progressive scanning type, as video signals of two channels, compresses the amount of information of the video signals of the two channels with compressing units of two channels, and transmits the compressed video signals of two channels to a peripheral device in the compressed state.

Image pickup apparatus

A camera-integrated VTR is arranged to detect an image shake according to a control error signal of a driving control system provided for recording or reproduction by moving a tape and a head relative to each other and to correct the image shake by supplying the result of detection to an image-shake correction circuit.

Electronic apparatus having image-shake correcting device

An apparatus for recording a video signal while forming a multiplicity of recording tracks in parallel on a tape-shaped recording medium, wherein camera information representing the operating state of a camera when shooting each picture is recorded in a position corresponding to the recorded track of that picture so that the operating state of the camera at the time of taking the video signal which has already been recorded can reappear. Therefore, in a case where a video signal is recorded in continuity with this recorded portion, the camera operating state is controlled in a joint portion of these to improve the continuity in this joint portion.

Recording apparatus for a video signal and a control information

A delay apparatus comprises one or a plurality of shift registers, a plurality of signal accumulating capacitors which are mutually coupled by transfer transistors, a plurality of write switches each of which is arranged between an input terminal and either one of the capacitors and which are controlled by outputs of the shift registers, and a plurality of read switches which are arranged between the plurality of capacitors and an output terminal and are controlled by the outputs of the shift registers, wherein the signal charges accumulated in the one capacitor are capacitively divided into other capacitors through the transfer transistors for transferring the signal charges.
