An analyzing apparatus extracts, from a food image, food information relating to types and served states of foods included in the food image and an edible portion of each food, calculates an area ratio between the edible portion of the same kind of food extracted from a plurality of food images acquired at different timings, stores conversion information for converting the area ratio into a volume ratio corresponding to each type and served state of food, and converts the area ratio of each food into a volume ratio using the stored conversion information corresponding to the food whose area ratio is to be converted from among the stored conversion information based on the food information.

A packing member includes a structure for accommodating an object-to-be-accommodated and a cylindrical sheet for covering the structure. The cylindrical sheet includes a first portion having a heat contraction property and includes a second portion having an elasticity higher than that of the first portion. The first portion has a display portion. The display portion is provided on a surface extending along a predetermined direction of the structure. Free end portions of the first portion and the second portion contract to surround an end surface of the structure crossing the predetermined direction of the structure.

An image processing apparatus includes a memory that stores instructions, and at least one processor that executes the instructions to acquire measurement signals including information on a tomography of a subject in a depth direction obtained by performing optical coherence tomography on the subject, to acquire a base signal based on the measurement signals, and to calculate phase shifts between the measurement signals and the base signal. The processor further executes the instructions to smooth the phase shifts, to adjust phases of the measurement signals corresponding to the smoothed phase shifts based on the smoothed phase shifts, and to generate a background signal corresponding to a noise component based on the phase-adjusted measurement signals. In addition, the processor subtracts the background signal from the phase-adjusted measurement signals, and generates a tomographic image of the subject based on the phase-adjusted measurement signals from which the background signal is subtracted.

An ophthalmologic apparatus includes an error obtaining unit configured to obtain a value corresponding to a difference between a first imaging position which tracks a predetermined position of an eye portion under control of a tracking unit and the predetermined position, a determination unit configured to determine a position which is shifted from the first imaging position which tracks the predetermined position as a second imaging position in accordance with the value corresponding to the difference. The ophthalmologic apparatus averages tomographic images of the first and second imaging positions.

A packing member for packing an article, includes a medium accommodating portion for accommodating medium; a non-return valve for passing the medium to the medium accommodating portion and stopping the medium away from the medium accommodating portion; an introducing portion for introducing the medium into the medium accommodating portion with the non-return valve from an outside of the packing member to balloon the medium accommodating portion; and a sealing region, disposed upstream of the non-return valve with respect to a direction of the introduction of the medium from the introducing portion toward the non-return valve, for sealing against the introduction of the medium to prevent leakage from the introducing portion to an outside of the packing member, the sealing region being sealed to keep the medium in the medium accommodating portion.

Packing method, packing member and manufacturing method therefor

The present invention provides a magnetic head of which magnetic core is composed of thin plates of a high magnetic permeability, each provided with an adhesive layer comprising a granular substance. In such structure, the stress relaxation achieved by said granular substance prevents the loss of effective magnetic permeability of said core, thereby improving the high frequency characteristics. Also the presence of said granular substance realizes a hardness in the vicinity of said adhesive higher than that of said thin plates of a high magnetic permeability, thereby improving the abrasion resistance of said core. Furthermore said adhesive layer is rendered satisfactorily thinner than said thin plate to prevent the loss of sensitivity. Furthermore a fixing member for supporting said core is made of such a composition as to be evenly abraded with said core, thereby preventing deformation of the head resulting from abrasion by the recording medium and thus enabling to maintain the initial electromagnetic converting characteristics over a prolonged period.
