Image sensor and electronic camera
摘要
說明書
The image sensor 3 may be, for instance, a CMOS image sensor. The image sensor 3 captures a subject image formed via the image-capturing optical system 2. As will be described in detail later, a plurality of pixels, each having a photoelectric conversion unit, are arranged in a two dimensional array at the image sensor 3. The photoelectric conversion unit may be constituted with, for instance, a photodiode (PD). The image sensor 3 generates pixel signals through photoelectric conversion of light having entered therein and outputs the generated pixel signals to the control unit 4. A pixel signal is generated based upon an electric charge resulting from photoelectric conversion at the photoelectric conversion unit.
The memory 5 may be, for instance, a recording medium such as a memory card. Image data and the like are recorded into the memory 5. Data are written into and read out from the memory 5 by the control unit 4. The display unit 6 displays, an image based upon image data, photographic information indicating the shutter speed, the aperture value, etc., a menu screen and the like. The operation unit 7, which includes a release button, various setting switches such as a power switch, and the like, outputs an operation signal corresponding to a given operation to the control unit 4.
