An imaging apparatus includes an interchangeable lens, and a camera body. The interchangeable lens includes a correction lens, a lens driver, and a first controller. The camera body includes an image sensor, a sensor driver, and a second controller. The first or second controller selects one of the interchangeable lens and the camera body, in accordance with a level of correction capability to perform the image stabilization. Corresponding to the selected one, one driver of the lens driver and the sensor driver performs the image stabilization for the image blur within a predetermined range. The other driver corresponding to non-selected one performs the image stabilization for a remaining portion of the image blur exceeding the predetermined range.

A lens apparatus attachable to an imaging apparatus via an accessory, the lens apparatus includes an acquirer configured to acquire first power information indicating power available for the accessory, a determiner configured to determine second power information indicating power available for the lens apparatus based on the first power information, and a transmitter configured to transmit, to the imaging apparatus, the second power information or power information relating to the first power information and the second power information.

The present invention is directed to a method and means for enabling contact lens wearers to photograph their own eyes using an electronic device with a camera such as an iPhone with a macro lens, for example, Olloclip® Macro Pro Lens Set 7× lens, and a custom three-dimensional printed eyecup attachment. The eyecup attachment is designed to position the camera at a suitable and reproducible distance from the eye to ensure that the system can focus appropriately on the lens details. The eyecup attachment also serves to block stray light and diffuse the ambient lighting. In addition, the eyecup attachment ensures that the camera is held in the correct orientation while photos are being captured. The capture images are analyzed using image processing software to determine the angel of rotation of the contact lens.

An imaging element incorporates a reading portion that reads out captured image data at a first frame rate, a storage portion that stores the image data, a processing portion that processes the image data, and an output portion that outputs the processed image data at a second frame rate lower than the first frame rate. The reading portion reads out the image data of each of a plurality of frames in parallel. The storage portion stores, in parallel, each image data read out in parallel by the reading portion. The processing portion performs generation processing of generating output image data of one frame using the image data of each of the plurality of frames stored in the storage portion.
