摘要： In an image sensor having a plurality of pixels which photoelectrically convert a subject image, a plurality of pairs of focus detection pixels including first focus detection pixels (SHA) and second focus detection pixels (SHB) are arranged while being distributed. The layouts of the first focus detection pixel (SHA) and the second focus detection pixel (SHB) are switched in pairs of focus detection pixels adjacent in the focus detection direction. Focus detection is performed using image waveforms obtained from the first focus detection pixel (SHA) and the second focus detection pixel (SHB) whose layouts are switched. This reduces focus detection errors generated when the pixels included in the pairs of focus detection pixels receive light fluxes from different portions of the subject.

摘要： If the size of an error portion within an image of the frame of interest is equal to or larger than a threshold and it is determined that no error portion exists within an image of a frame immediately before the frame of interest, a display unit (115) is caused to display the image of the frame immediately before the frame of interest as the image of the frame of interest. If the size of an error portion within the image of the frame of interest is smaller than the threshold and it is determined that an error portion exists within the image of the frame immediately before the frame of interest, the display unit (115) is caused to display a result obtained by correcting the error portion within the image of the frame of interest using a pixel group surrounding the error portion.

摘要： In a conventional power MOSFET, an electric field concentration occurs at a gate electrode bottom portion on the outermost periphery of an operating area, thereby causing a deterioration in high voltage strength between the drain and the source, or between the collector and emitter. In this invention, a trench at the outermost periphery of an operating area is shallower than trenches of the operating area. Thereby, the electric field concentration at the gate electrode bottom portion on the outermost periphery of the operating area is relieved, and a deterioration in high voltage strength between the drain and source is suppressed. Furthermore, by narrowing the outermost peripheral trench aperture portion, trenches different in depth can be formed by an identical step.
