There is provided an encoding apparatus. A data processing unit generates binary data by performing data processing, including binarization processing, with respect to image data that has been input from an image capturing unit. An arithmetic coding unit generates arithmetic code data by performing arithmetic coding of the binary data. A control unit performs control so as to record the arithmetic code data into a recording unit. When the image data is still image data generated during continuous shooting of still images, the control unit performs control so as to record the binary data into the recording unit without generating the arithmetic code data.

Encoding apparatus, image capturing apparatus, control method, and storage medium

An image processing apparatus which calculates a code amount obtained upon coding a coding block being obtained by dividing an image to be processed, determines an assigned code amount to be assigned to each of the coding blocks, based on a reference code amount and the code amount calculated for each of coding blocks in a coding group including a plurality of coding blocks, and generates coded data by coding each of the coding blocks using the assigned code amount as a target code amount, wherein the assigned code amount is determined so that a total of the assigned code amounts of the coding blocks in the coding group is the same among a plurality of coding groups, and fixed-length coding is carried out on a coding group-by-coding group basis by coding using the determined assigned code amounts.

Image processing apparatus, image processing method, and non-transitory computer-readable storage medium

An image capturing apparatus includes an image capturing unit configured to capture an image of an object and generate image data, a compression unit configured to compress the image data generated by the image capturing unit, a display control unit configured to decode the image data compressed by the compression unit and display the decoded image data on a display unit, and an instruction unit configured to issue an instruction to magnify an image to be displayed on the display unit, wherein, in a case where the instruction unit issues the instruction to magnify the image to be displayed on the display unit, the compression unit reduces a compression rate of the image data.
