Abstract: Provided is an imaging element including a photoelectric conversion unit formed by stacking a first electrode, a photoelectric conversion layer and a second electrode. The photoelectric conversion unit further includes a charge storage electrode which is disposed to be spaced apart from the first electrode and disposed opposite to the photoelectric conversion layer via an insulating layer. The photoelectric conversion unit is formed of N number of photoelectric conversion unit segments, and the same applies to the photoelectric conversion layer, the insulating layer and the charge storage electrode. An nth photoelectric conversion unit segment is formed of an nth charge storage electrode segment, an nth insulating layer segment and an nth photoelectric conversion layer segment. As n increases, the nth photoelectric conversion unit segment is located farther from the first electrode. A thickness of the insulating layer segment gradually changes from a first to Nth photoelectric conversion unit segment.

Abstract: In an arithmetic processing device, a controller includes: a second non-linear converter that, when a selector has branched off to a second processing side, performs non-linear arithmetic processing on the result of a cumulative addition processing of a first adder; and a second pooling processing part to which the results of the cumulative addition processing of k first adders that have been subject to the non-linear arithmetic processing by the second non-linear converter are inputted, the second pooling processing part performing a pooling process on the simultaneously inputted data. A data-storing memory manager writes the same data to k different data-storing memories when the number of input feature map data is less than or equal to N/k. The controller performs a control so that the selector branches off to the second processing side when the number of input feature map data is less than or equal to N/k.

Abstract: An image processing apparatus receives an image signal and generates a display image having an image range associated with a display area of a display unit from an image based on the image signal. The image processing apparatus includes a position-of-interest-calculating-unit, a frame-out-accuracy-calculation-unit, an alteration-variable-decision-unit and an image-alteration-unit.

The alteration-variable-decision-unit decides a processing variable of alteration processing performed with respect to the image in conformity with the frame-out accuracy.
