摘要： An image pickup apparatus includes an image sensor including a color filter having pixels of different colors arranged in a predetermined order and a demosaic processor. The image sensor receives a subject image and outputs an image signal including color signals of the different colors. The demosaic processor generates color signals of the different colors for each of pixels of the image from the image signal. The demosaic processor includes a generation unit and a noise reduction unit. The generation unit performs computation using a target color signal representing a predetermined target color signal included in the image signal and a predetermined different color signal so as to generate a color-related signal that associates the target color signal with the predetermined different color signal for a pixel of the target color signal. The noise reduction unit performs a noise reduction process on the color-related signal generated by the generation unit.

摘要： An image pickup device and associated methodology are provided. The image pickup device is formed from a plurality of pixels, each of which can perform any of an exposure operation and a reading operation thereof at a timing different from that of the other, an imaging apparatus is provided, which can determine the amount of main-flashing light based on pre-flashing by a flash highly accurately. Before and during a preflash operation by a flash unit, an exposure operation is started simultaneously for all the pixels of the image pickup device 14 to form an image before and during the preflash to obtain a detected value by a detector before and during the preflash, respectively. A computation circuit computes a differential detected value obtained by subtracting the before-preflash detected value from the during-preflash detected value. The differential detected value is a detected value containing only pre-flashed light with ambient light excluded. An amount of light for main flashing is computed on the basis of the differential detected value.

摘要： A signal detection circuit and a controller receive signals from an imaging device, determine pixels having signal levels that exceed a predetermined defect determination level as defective pixels, and store the addresses of the defective pixels corresponding to read methods. When the imaging device images an object, a defect compensation circuit reads the addresses of the defective pixels that have been stored corresponding to the read methods and performs a predetermined compensation process for the defective pixels. A controller stores the signal levels of the defective pixels and converts the signal levels corresponding to the read methods. As a result, when defective pixels are detected in one read method, the defective pixels can be compensated in a plurality of read methods.
