Abstract: An image processing apparatus can execute appropriate image processing while preventing increase in a capacity of a memory for storing a plurality of pieces of image data of different frequency bands. The image processing apparatus stores first image data having the highest frequency among the plurality of pieces of image data of different frequency bands in a state in which each pixel of the first image data includes a color component signal of any of a plurality of colors, on the memory, and further stores second image data and third image data whose frequency bands are lower than that of the first image data on the memory, in a state in which a part of or all pixels of the second and the third image data have color component signals of a plurality of colors.

Abstract: A first generation unit generates a RAW image reduced in the horizontal direction from a RAW image including pixels each having single-color signal information, by limiting the band of spatial frequencies in the horizontal direction and decreasing the number of pixels in the horizontal direction. The RAW image reduced in the horizontal direction is stored in a line memory. A second generation unit generates a reduced RAW image by decreasing, at least in the vertical direction, the number of pixels of the RAW image reduced in the horizontal direction. This makes it possible to generate a reduced RAW image using little memory capacity.

Abstract: The present invention has a configuration in which a reduction and interpolation circuit having a variable reduction ratio and at least one reduction circuit having a fixed reduction ratio are sequentially connected. In the case where a set reduction rate cannot be achieved in the reduction and interpolation circuit, a reduction ratio for the reduction and interpolation circuit is determined such that the set reduction ratio can be achieved through a combination of the reduction ratio of the reduction and interpolation circuit and the reduction ratio of the reduction circuit. It is thereby possible to obtain an image processing apparatus capable of generating a reduced image reduced at a high reduction ratio and having high image quality while suppressing the circuit size.

Abstract: The present invention allows still images to be recorded during moving image recording, and does not require frame data to be generated and written for all frames missed as a result of the still image recording. Thus, when the recording of a still image is instructed during moving image recording, the moving image recording is interrupted, and the number of moving image frames missed during the still image recording is counted. The still image obtained by an image sensing device is shot, and the shot still image data is stored on a memory card. Next, a pseudo moving image frame is generated from the still image data and appended to the interrupted moving image file. Moving image recording is then resumed. Offsets are adjusted at this time so that the counted missing frames point to the pseudo frame.

Abstract: In response to an input instruction to start a still image capturing operation when a moving image capturing operation is being performed, an imaging apparatus controls the still image capturing operation to record a still image file on a recording medium, interrupts the moving image capturing operation, generates a moving image in which an interframe-compressed image whose difference information is zero is inserted as at least one of images to be substituted for a moving image corresponding to a time period for which the moving image capturing operation is interrupted, and records the generated moving image on the recording medium.
