Problems solved by technology
As described above, the readout circuit cannot perform the readout operation of the signals C and E, and therefore cannot generate image signals of moving images corresponding to the signals C and E.
As a result, there will be dropped frames in the frames corresponding to signals C and E

Embodiment Construction
[0030]The present invention relates to the operation of an imaging device having an image sensor when performing parallel shooting of still images and moving images. The imaging device is, for example, a digital still camera or a digital video camera with a parallel shooting function. The image sensor is, for example, a CCD image sensor or a CMOS image sensor.
[0031] will refer to figure 1 An imaging apparatus 100 according to a first embodiment of the present invention is explained. figure 1 is a block diagram of the structure of the imaging apparatus 100 according to the first embodiment of the present invention.
[0032] The imaging apparatus 100 has a first mode and a second mode. In the first mode, only moving image shooting is performed. In the second mode, parallel shooting of still images and moving images is performed.
[0033] The lens 101 forms an optical image of a subject on the imaging surface (pixel array 103 a ) of the image sensor 103 . At this time,...

The system control unit (107) executes the following control when switching the mode from the first mode to the second one. When the first accumulation period is shorter than the first readout period,The system control unit (107) executes the following control when switching the mode from the first mode to the second one. When the first accumulation period is shorter than the first readout period, the system control unit (107) controls the image sensor driving circuit (109) and readout circuit so that the sum of the first and second readout periods fits into a 2-frame period. When the first acthe system control unit (107) controls the image sensor driving circuit (109) and readout circuit so that the sum of the first and second readout periods fits into a 2-frame period. When the first accumulation period is longer than the first readout period, the system control unit (107) controls the image sensor driving circuit (109) and readout circuit so that the sum of the first accumulation pcumulation period is longer than the first readout period, the system control unit (107) controls the image sensor driving circuit (109) and readout circuit so that the sum of the first accumulation period and second readout period fits into a 2-frame period.eriod and second readout period fits into a 2-frame period.
Description
technical field [0001] The invention relates to an imaging device and a method for controlling the imaging device. Background technique [0002] Some image pickup apparatuses such as digital still cameras and digital video cameras have both a function of performing moving image shooting and a function of performing still image shooting. In an imaging device, an image sensor such as a CCD sensor or a CMOS sensor includes a pixel array and a readout circuit for reading out a signal from the pixel array, wherein, in the pixel array, photoelectric conversion units are arranged in a row direction and a column direction multiple pixels. [0003] According to the technique disclosed in Japanese Patent Application Laid-Open No. 2001-352483, an image pickup device switches the readout circuit driving method from a first driving method suitable for moving image shooting to a second driving method suitable for still image shooting between consecutive frame periods. Two drive methods....
