Abstract
Disclosed is an imaging apparatus which performs efficient JPEG compression encoding by dividing an image after an image processing into a plurality of blocks and then performing JPEG compression, and also generates a natural compressed image. The imaging apparatus includes an image processor for generating image data from a light input into an imaging device, an encoder for encoding the image data to generate encoded image data, and a storage unit for storing the encoded image data.
Claims5
An imaging apparatus comprising:
- an image processor for generating image data from a light input into an imaging device;
- an encoder for encoding the image data to generate encoded image data;
- and
- a storage unit for storing the encoded image data,
- wherein the image processor horizontally divides the image data into a plurality of blocks and supplies the divided blocks to the encoder, and includes one or more filter units for performing a predetermined filter processing for the image data and a filter controller for controlling the filter processing of the filter unit,
- wherein the filter controller acquires a number of vertical pixels of the image data, and controls the one or more filter units such that when the number of vertical pixels of the image data is indivisible by a number of vertical pixels corresponding to a preset encoding unit, data in a last row of the image data is copied and the copied data is added to the image data until the number of vertical pixels of the image data is divisible.

An image processing method comprising:
- performing image processing by generating image data from light input into an imaging device;
- encoding the image data to generate encoded image data;
- and
- storing the encoded image data,
- wherein when the image data is horizontally divided into a plurality of blocks during image processing, the image data is encoded without passing through storing the encoded image data,
- wherein performing the image processing includes performing filter processing by one or more filters by performing a predetermined filter processing for the image data and performing a filter control by controlling the filter processing the one or more filters, and
- performing the filter control includes calculating a number of vertical pixels of the encoded image data and, when the number of vertical pixels of the image data is indivisible by a number of vertical pixels corresponding to an encoding unit in encoding the image data, controlling the filter processing such that data in a last row of the image data is copied and the copied data is added to the image data until the number of vertical pixels is divisible.
