Image sensor and electronic device

An electronic device comprising:

• an image sensor,
• wherein the image sensor includes:
• a pixel unit configured to generate a full-size original image corresponding to incident light with a plurality of photoelectric conversion elements;
• a holding unit having a capacity capable of holding at least the full-size original image;
• and
• an processing unit configured to:
• generate a full-size processed image by performing predetermined image processing with respect to the full-size original image read from the holding unit,
• generate a modified-size processed image by modifying a size of the full-size processed image, and
• serially or simultaneously output both the full-size processed image and the modified-size processed image,
• the processing unit is configured to generate a size-reduced original image by reducing a size of the full-size original image generated by the pixel unit,
• the holding unit has a capacity capable of holding at least the full-size original image and the size-reduced original image,
• the pixel unit is configured to supply the generated full-size original image to the processing unit and also to cause the holding unit to hold the generated full-size original image,
• the processing unit is configured to cause the holding unit to hold the size-reduced original image generated by reduction of the size of the full-size original image,
• the processing unit is configured to generate a size-reduced processed image by performing predetermined image processing with respect to the size-reduced original image read from the holding unit, and also to supply the full-size processed image generated by the predetermined image processing performed with respect to the full-size original image read from the holding unit, and
• the processing unit is configured to generate the modified-size processed image by modifying a size of the supplied size-reduced processed image and to perform an output thereof, and also to directly output the supplied full-size processed image.
