Abstract: A search is enabled for an adjustment value with which a good blur correction effect is obtained by blur correction processing as an optical adjustment value of an image projection device, and blur correction performance is improved in a case where correction of a focus blur that occurs in a projection image is performed by signal processing.

Abstract: Provided is a computation method for obtaining information suitable for positional deviation correction and lens blur correction for a case where a part of or an entire projection image projected by each of a plurality of projectors is displayed in a superimposed manner. For this purpose, a light intensity distribution indicating a degree of lens blur of a base projector and peak coordinates of the light intensity distribution are calculated using a captured image obtained by capturing a test pattern projected by the base projector in an arrangement state in which a plurality of projectors is arranged such that a part of or an entire projection image projected by each of the plurality of projectors is displayed in a superimposed manner.

Abstract: A status change estimating unit 501 estimates a change in lens status of an interchangeable lens 21. A warning control unit 502 determines whether user setting lens status set by a user for the interchangeable lens 21 through a user interface unit 41 or a communication unit 43 and interchangeable lens status are the same. In a case where the warning control unit 502 determines that the user setting lens status and the interchangeable lens status are different from each other, the warning control unit 502 outputs warning information to a warning unit 42 to warn the user. This configuration enables the user to recognize a difference between the user setting lens status and the interchangeable lens status by the warning issued by the warning unit 42.

Abstract: In a case where it is determined by a reliability determination section 501 that retention aberration information of an in-apparatus aberration information retention section 31 is unreliable, a control section 50 sets detection aberration information generated by performing aberration detection processing by a lens aberration detection processing section 32 as application aberration information for correcting an aberration of a captured image. In a case where it is determined that the retention aberration information is reliable, the control section 50 sets the retention aberration information as the application aberration information. Aberration information can be generated if necessary.

Abstract: An image on which a noise reduction and a dynamic range expansion process have been performed is generated by a sequential synthesis process using continuous-photographed images of different exposure conditions. The continuous-photographed images of different exposure conditions are input, configuration pixels of an input image and an intermediate synthetic image are classified into a noise pixel, an effective pixel, or a saturation pixel, a synthesis processing method of a pixel unit is decided according to a combination of pixel classification results of the corresponding pixels, and the intermediate synthetic image is updated according to the decided method.
