Abstract: The imaging device comprises: an imaging unit, a shooting processor, an exposure information setter, and an image processor. The imaging unit stores electric charges in response to an incident light for each frame, thereby outputting an image signal. The shooting processor controls storage times, during which the imaging unit stores the electric charges. The exposure information setter sets first exposure control information that controls brightness of a first image signal generated based on a first storage time and second exposure control information that controls brightness of a second image signal generated based on a second storage time. The image processor combines the first and the second image signal. In the case where the first exposure control information satisfies a given condition, the exposure information setter sets the first and the second exposure control information such that storage times corresponding to frames adjacent to each other become equal to each other.

Abstract: The present disclosure aims to achieve a more effective image in slow motion. An imaging apparatus of the present disclosure includes an image sensor that outputs image data at a first frame rate and an image processor. The image processor: (i) generates motion image data having a second frame rate that is 1/N of the first frame rate, based on the image data having the first frame rate output from the image sensor, for frames not provided with a given instruction, (ii) generates motion image data having the first frame rate based on the image data having the first frame rate output from the image sensor, for frames provided with a given instruction and (iii) processes the generated motion image data having the first frame rate and the generated motion image data having the second frame rate as a series of motion image data.

Abstract: An image processing apparatus comprises: a separation unit configured to separate image data into a luminance signal and a color difference signal; a decision unit configured to decide a reference pixel, which is referenced for a pixel of interest included in the image data; a luminance noise reduction unit configured to reduce luminance noise in the luminance signal of the image data; a weight calculation unit configured to calculate a weight of the reference pixel based on similarity of luminance included in the luminance signal having been subjected to noise reduction by the luminance noise reduction unit between a first area containing the pixel of interest and a second area containing the reference pixel; and a color noise reduction unit configured to reduce color noise in the color difference signal for the pixel of interest by using the weight of the reference pixel.
