no. 1 Embodiment approach

[0050] Next, a first embodiment which is one embodiment of the present invention will be described with reference to the drawings.

[0051] figure 1 It is a block diagram showing the configuration of the imaging device 1 according to the first embodiment which is one embodiment of the present invention. Such as figure 1 As shown, the imaging device 1 is composed of the following parts: the imaging optical system 10, which guides the subject image to the imaging element 20, and makes it form an image; the imaging element 20, which performs photoelectric conversion on the imaged object image and outputs and an image processing unit 30 that applies predetermined signal processing to the output signal output from the imaging element 20 to reproduce a subject image. Based on the image data corresponding to the image of one frame output from the image processing unit 30, the image data of the still image is generated, and based on the image data corresponding to the plurality of f...

no. 2 Embodiment approach

[0119] Below, refer to Figure 8 A second embodiment which is another embodiment of the present invention different from the first embodiment will be described. The difference between the second embodiment and the first embodiment lies in the specific circuit configuration of the imaging element 20 and its control method, and other configurations are the same as those of the first embodiment, and thus description thereof will be omitted.

[0120] Figure 8 It is a specific circuit configuration diagram of the imaging element of the second embodiment. exist Figure 8 A circuit is shown in which three unit circuits 140 corresponding to the unit grid of the Bayer array are arranged in the row direction and two in the column direction. In the actual circuit configuration, a number equivalent to the total number of pixels of the imaging element of the second embodiment is arranged in the row direction and the column direction, Figure 8 The unit circuit 140 and its surrounding ...

no. 3 Embodiment approach

[0129] Below, refer to Figure 9 A third embodiment which is another embodiment of the present invention will be described. The third embodiment differs from the first embodiment in that the imaging element supports interlace output in which odd-numbered field output for outputting odd-numbered lines and even-numbered field output for outputting even-numbered lines are alternately repeated. In addition, in the third embodiment, the addition mode of the pixel signal in the imaging element is configured differently from that in the first embodiment, thereby allowing the imaging element to support interlaced output.

[0130] Figure 9 (a) and Figure 9 (f) represents the substitution adopted in the third embodiment figure 2 In (c), configuration of the addition mode when pixel signals are added. Figure 9 (a) represents the configuration of the addition mode corresponding to the odd field output, Figure 9 (f) shows the configuration of the addition mode corresponding to ev...

Abstract

This invention makes it possible to generate a high-quality image signal without making a pixel configuration for the purposes of pixel addition difficult, while maintaining, within an appropriate range, the operation speed and power consumption required to read pixels. A single FD (24) is shared among four photoelectric conversion elements (21). These four photoelectric conversion elements (21) correspond to a two-row-two-column unit grid of a Bayer array. A signal transfer unit (22) simultaneously transfers, to the FD (24), the output signals from the two photoelectric conversion elements (21) which correspond to different colors. The output signals from the remaining two photoelectric conversion elements (21) are also transferred simultaneously to the FD (24). This results in the pixel signal being added up. From the added pixel signal, an imaging element (20) generates a digital image signal comprising G and Mg pixel signals, and a digital image signal comprising Ye and Cy pixel signals, and outputs said pixel signals to an image processing unit (30).

Description

technical field [0001] The present invention relates to an imaging device, and more particularly, to an imaging device in which color filters are arranged in a Bayer array, a driving device for the imaging device, a driving method for the imaging device, an image processing device, a program, and an imaging device. Background technique [0002] In recent years, digital cameras supporting high-speed moving image recording such as HD (High Definition: high-definition) moving images have been provided. As a requirement for image photography of still images, an image sensor of 12M (mega) pixels is used. On the other hand, in HD moving images, the number of output pixels is 1920 horizontal pixels and 1080 vertical pixels, and the total number of output pixels is 2.1M pixels. Therefore, in order to realize a digital camera that captures high-definition still images and HD moving images using the same image sensor, a configuration is required that limits the number of pixels outpu...
