Imaging device, method for controlling imaging device, and storage medium storing a control program

A control method for an imaging apparatus comprising an image pickup device comprising a plurality of photoelectric conversion elements arrayed in a predetermined first direction and a second direction intersecting with the first direction, an amplification section that treats as respective common pixels (K×L) pixels in the first direction and the second direction (wherein K, L are integers of 2 or more), and amplifies an image capture signal for each of the common pixels, and a color filter that is provided above a plurality of pixels configured by the plurality of photoelectric conversion elements, the color filter having a repeatedly disposed basic array pattern that includes a first filter corresponding to a first color that contributes most to obtaining a brightness signal, and second filters respectively corresponding to 2 or more second colors other than the first color, placed in a predetermined pattern of (N×M) pixels in the first direction and the second direction (wherein N>K and M>L), the control method comprising:

• performing charge sweeping by applying sequential shutter pulses to the image pickup device in turn to each pixel, or to each scan line running along the second direction, or to each of groups of a plurality of pixels on a scan line running along the second direction, and reading from the image pickup device pixel signals of the plurality of pixels at a set cycle;
• generating, from the read pixel signals, line image data of pixels, from out of the plurality of pixels, that are arrayed running along the second direction at a cycle of from K pixels to N pixels in the first direction;
• and
• generating image data based on the line image data.

A non-transitory storage medium storing a control program that causes processing to be executed in a computer that controls an imaging apparatus equipped with an image pickup device comprising a plurality of photoelectric conversion elements arrayed in a predetermined first direction and a second direction intersecting with the first direction, an amplification section that treats as respective common pixels (K×L) pixels in the first direction and the second direction (wherein K, L are integers of 2 or more), and amplifies an image capture signal for each of the common pixels, and a color filter that is provided above a plurality of pixels configured by the plurality of photoelectric conversion elements, the color filter having a repeatedly disposed basic array pattern that includes a first filter corresponding to a first color that contributes most to obtaining a brightness signal, and second filters respectively corresponding to 2 or more second colors other than the first color, placed in a predetermined pattern of (N×M) pixels in the first direction and the second direction (wherein N>K and M>L), the processing comprising:

• a reading step of performing charge sweeping by applying sequential shutter pulses to the image pickup device in turn to each pixel, or to each scan line running along the second direction, or to each of groups of a plurality of pixels on a scan line running along the second direction, and reading from the image pickup device pixel signals of the plurality of pixels at a set cycle;
• a step of generating, from the read pixel signals, line image data of pixels, from out of the plurality of pixels, that are arrayed running along the second direction at a cycle of from K pixels to N pixels in the first direction;
• and
• a step of generating image data based on the line image data.
