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： In an image acquisition apparatus, RAW data obtained in image acquisition with an imager in which a color filter is disposed in a front face is divided into each identical color by a RAW data dividing unit, a compression coding processing unit produces coded data of each color by compressing the RAW data at a compression rate controlled for each color, and the coded data of each color is recorded in a recording unit. A motion compensation unit compensates a relative positional relationship between frames by estimating a motion of a subject between frames of plural images, using specific color division coded data which is decoded by the compression coding processing unit and a RAW format data reproducing unit, the specific color division coded data being coded data of a color close to a peak of spectral sensitivity of human vision in the coded data of each color.

摘要： An image signal generated by a CCD image sensor is processed by the block-generating section 28 provided in an image-signal processing section 25. A class tap and a prediction tap are thereby extracted. The class tap is output to an ADRC process section 29, and the prediction tap is output to an adaptation process section 31. The ADRC process section 29 performs an ADRC process on the input image signal, generating characteristic data. A classification process section 30 generates a class code corresponding to the characteristic data thus generated and supplies the same to an adaptation process section 31. The adaptation process section 31 reads, from a coefficient memory 32, the set of prediction coefficients which corresponds to the class code. The set of prediction coefficients and the prediction tap are applied, thereby generating all color signals, i.e., R, G and B signals, at the positions of the pixels which are to be processed.
