Abstract: A control device of a projection apparatus that projects an image from a display portion displaying the image based on input image data to a projection object through an optical system, includes: a correction portion that corrects the input image data by performing first processing of increasing pixel values of pixels of the input image data corresponding to a specific region determined by a light quantity distribution in a surface of the projection object in the image projected to the projection object, and second processing of uniformly decreasing each of pixel values of pixels of the input image data by a first pixel amount.

Abstract: A shake correction control device includes an acquisition unit that acquires imaging information for selecting mechanical correction of mechanically performing shake correction of a subject image or electronic correction of electronically performing the shake correction of the subject image, and a shake correction control unit. The shake correction control unit performs a first control for performing a switching control from the mechanical correction to the electronic correction by synchronizing shake correction operations of the mechanical correction and the electronic correction and a second control, different from the first control, for performing a switching control from the electronic correction to the mechanical correction based on the imaging information acquired by the acquisition unit.

Abstract: Disclosed are a distance image acquisition apparatus and a distance image acquisition method capable of achieving high distance measurement accuracy and omitting wasteful imaging or calculation. The distance image acquisition apparatus (10) includes a distance image sensor (14), a drive mode setting unit (20A), a distance image generation unit (20B), a pulse light emission unit (22), and an exposure control unit (24). The exposure control unit (24) controls emission and non-emission of pulse light emitted from the pulse light emission unit (22) according to a drive mode set by the drive mode setting unit (20A), and controls exposure in the distance image sensor (14). The distance image generation unit (20B) performs calculation processing of a sensor output acquired from the distance image sensor (14) according to the drive mode set by the drive mode setting unit (20A) to generate a distance image corresponding to a distance of a subject.

Abstract: A system control unit consecutively images a subject by driving based on a global shutter method, divides captured image data obtained by the imaging into a plurality of areas, and each time each area is generated, compares the generated area with the same area as the area in the captured image data generated by the imaging performed before the imaging, and detects a moving object from the area based on a result of the comparison. Based on a change in position of the detected moving object, the system control unit predicts a timing at which a trigger range TR set in the captured image overlaps with the moving object, and performs automatic imaging in a frame period that includes the timing.

Abstract: A digital camerathat includes an imaging sensor having a stop 2 arranged in front of an imaging surface includes an imaging control unit that starts exposure of pixels on the entire imaging surface at the same time and then, ends the exposure of the pixels at the same time in a state where light from a subject is incident on the imaging surface, by controlling an imaging sensor drive circuit which drives the imaging sensor, and a processr that sequentially changes an F number of the stop 2 to a plurality of values during a period from the start of the exposure until the end of the exposure. The processr controls a time in which the F number is maintained at each of the plurality of values to be a time that is based on a function indicating light transmittance characteristics of an APD filter.

Abstract: A digital camera includes an imaging control unit that images a subject by performing driving based on a rolling shutter method on an imaging sensor, and a light emission control unit that emits auxiliary light a plurality of times from a light emission device while the imaging is performed. A difference At between start timings of exposure started by the driving in two adjacent pixel rows is a value other than 1/n (n is an integer greater than or equal to 1) of an exposure time in which the exposure is performed. The light emission control unit controls a light emission cycle of the auxiliary light to be a time that is m (m is an integer greater than or equal to 1) times the difference.

Abstract: An imaging apparatus includes an imager, an imaging controller and a display controller as defined herein, a time required for the first rolling readout drive is longer than a time required for each of the rolling reset drive, the rolling shutter drive and the second rolling readout drive, and in an imaging mode in which the imaging controller performs the first drive while continuously performing the second drive, the imaging controller sets a first start timing of the second drive performed first after a start of the first drive to be during an implementation period of the first rolling readout drive in the first drive, and synchronizes a second start timing of the rolling shutter drive performed first after the start of the first drive with the display update timing that comes first after an end of the first rolling readout drive.
