The imaging apparatus has an image sensor having a two-dimensional array of pixels. Each of the pixels includes an element operable to produce an electric charge by photoelectrically converting light from an imaged subject and a part operable to accumulate the produced charge and output an accumulated charge or a signal representing the accumulated charge.

摘要： A device is provided for taking high resolution still pictures while recording video without pausing video recording. Plural channels are provided for reaching pixel values from a CMOS sensor, and the output of each channel is input to a corresponding A/D conversion circuit. The channels are configured so that the pixels that are added together are read simultaneously. The data added by the pixel value adder is used as the video data for video recording. When a still picture is captured during video recording, the pixel data is stored in memory with capacity to store one frame, and is sequentially output from the image sensor as the still picture data.

摘要： When a method or apparatus of assuring simultaneous exposure, such as a mechanical shutter, is not provided with a MOS imaging sensor, moving subjects are distorted with a MOS image sensor when capturing a still image of a fast-moving subject because imaging and reading are not simultaneous across the MOS sensor. Changing the MOS sensor exposure sequence and reading sequence, and interpolating the read data, change and correct the read sequence line by line when imaging a high resolution moving image, and thus improve distortion in moving subjects.
