- step S ⁇ b> 76 the output selection unit 75 reads the full size processed image P ⁇ b> 3 from the DRAM 72 and outputs it to the outside of the image sensor 70. Thus, the image output process by the image sensor 70 is completed.
- the reduced size processed image P2 and the full size processed image P3 can be sequentially output from the image sensor 70 to the outside.
- the full size processed image P3 may be output first, and then the reduced size processed image P2 may be output.
- a plurality of different image data based on the full-size original image can be output.
- a still image composed of all pixels can be output during moving image shooting,
- the present invention can be used for the purpose of simultaneously outputting a preview image in which pixels are thinned out and a recording all pixel image.
- FIG. 15 shows a usage example in which the image sensors 10 to 70 are used.
- the image sensors 10 to 70 described above can be mounted on various electronic devices that sense light such as visible light, infrared light, ultraviolet light, and X-rays as follows.
- Devices for taking images for viewing such as digital cameras and mobile devices with camera functions
- Devices used for traffic such as in-vehicle sensors that capture the back, surroundings, and interiors of vehicles, surveillance cameras that monitor traveling vehicles and roads, and ranging sensors that measure distances between vehicles, etc.
