摘要： A drive method for a solid-state imaging device having an oblique pixel pattern includes the steps of: adding, separately for an odd-numbered row and an even-numbered row, x pixels in the horizontal direction and y pixels in the vertical direction, the x pixels and the y pixels having the same color, in an area having adjacent n pixels in the horizontal direction and adjacent n pixels in the vertical direction, where n is an odd number of three or greater and n≧x≧y; and repeatedly adding the x pixels and the y pixels while shifting the n×n area by m pixels in the vertical or horizontal direction, where m is an odd number of three or greater. The n×n area of odd-numbered rows is displaced from that of even-numbered rows by m pixels in the oblique direction in the oblique pixel pattern.

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： 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.
