摘要： An image pickup apparatus includes an image pickup element 10 that includes unit cells capable of individually reading signals from pixels that receive light beams transmitting through different pupil positions of an image pickup lens 5, a detector 20 that generates a pair of image signals in a pupil division direction using a signal from a pixel corresponding to each of the unit cells to perform focus detection based on a phase difference, a defective pixel storage unit 22 that stores defective pixel information, and a defective pixel compensating unit 20 that compensates a signal of a defective pixel based on an output of the defective pixel storage unit. The defective pixel compensating unit 20 compensates the signal of the defective pixel using a signal obtained from a pixel disposed in a direction different from the pupil division direction with respect to the defective pixel.

摘要： A focus detecting device having an auxiliary light mode, in which, when a focus is not appropriately first detected, a focus detecting operation for detecting the focus is executed with auxiliary light being projected. The focus detecting device includes a plurality of focus detecting areas, a detecting device for detecting a focus in each of the plurality of focus detecting areas, and a determination circuit for determining whether or not the focus detecting operation is to be executed in the auxiliary light mode based on the detected focus and a determination criterion, wherein the determination criterion is set to a predetermined value according to at least one of the plurality of focus detecting areas. Further, the focus detecting areas may be divided into groups each having at least two focus detecting areas, and the determination criterion can be set to a different predetermined value for each of the groups.

摘要： A picture display device using direct heating type linear cathodes as electron beam sources. Inorganic material vibration prevention elements having a hole thereon are provided. The linear cathodes penetrate the vibration prevention elements at one end part or both end parts of respective linear cathodes. This damps vibrations occurring at the time when an external force is applied and cuase them to cease rapidly.
