The present invention is a spherical magnesium oxide characterized in that: 10-2000 ppm of boron is contained; the total content of silicon and phosphorus is 300-4000 ppm; and the sphericity that can be read from the SEM photograph is 1.00-1.10, when the volume-based cumulative 50% particle diameter (D50) measured by means of a laser diffraction scattering particle size distribution measurement, is in the range of 3-200 ?m.

Abstract: An imaging apparatus includes: an image sensor generating original image data; an image processor performing image processing to generate image data; a storage storing a plurality of first parameter sets and at least one second parameter set; and a user interface receiving a user operation combining a first parameter set with a second parameter set. Each of the plurality of first parameter sets defines the effect in the image processing. Each of the at least one second parameter set defines a correspondence before and after color information in an image is converted. Based on the user operation, the image processor: adjusts an image indicated by the original image data, using the first parameter set included in the combination designated by the user operation; and converts color information included in the image adjusted by the first parameter set, using the second parameter set included in the designated combination.

Abstract: An imaging apparatus includes an imaging part to capture a subject so as to generate image data, an image processor to generate first image data having a first dynamic range relating to brightness based on the image data, a display being not compatible with reproduction of the image having the first dynamic range but being compatible with reproduction of an image having a second dynamic range narrower than the first dynamic range, and a controller to control a display of an image indicated by the first image data. The controller has a first mode in which when the first image data is displayed on the display, the controller converts a color gamut of the first image data to a color gamut with which the display is compatible without converting a gamma characteristic of the first image data.

Abstract: An image capture device according to the present invention includes: an optical system for producing a subject's image; an imager with multiple photodiodes, which reads an electrical signal representing the intensity of light that has been incident on each photodiode from the photodiode, thereby generating an image signal representing the subject's image; a controller, which acquires sensitivity information by photometry in order to adjust the sensitivity of the imager to light and which selects one of multiple methods for reading the electrical signal from each photodiode according to the sensitivity information acquired; and a driver for driving the imager by the reading method selected. The multiple reading methods include a mixing reading method, by which the electrical signals supplied from the photodiodes are added together and then output.

Abstract: The present invention provides an image capture device that can omit calculating a pulse signal that should otherwise be used to get a flash fired during a flash-ON sequential shooting operation. An image capture device includes: an image capturing section configured to capture a subject's image; a flashing section configured to store electricity and emitting flash light using the electricity; a power supply configured to supply the electricity; and a control section configured to control the supply of the electricity to the flashing section. If the flashing section performs preliminary flashing and main flashing sequentially, the control section supplies no electricity to the flashing section after the preliminary flashing is done and before the main flashing is performed for a first time.
